[0002] A proton exchange membrane fuel cell is a chemical reactor, in which hydrogen is decomposed into electrons and protons at the anode catalyst layer. The protons are transported to the cathode in the form of hydronium ions across the membrane and react with oxygen to generate water, which is discharged from the flow channel. The transport of protons across the membrane requires the proton exchange membrane to maintain a certain humidity, otherwise a large proton transfer resistance will be caused, affecting the power generation efficiency.

Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0031] The present embodiment provides a spray evaporation chamber with humidifier and intercooler functions, please refer to Figure 1 and Figure 3 , the spray evaporation chamber comprises:

[0032] At least one interlayer partition plate 1 is arranged horizontally in the spray evaporation chamber, which separates the spray evaporation chamber into at least two sub-spray evaporation chambers 100 from top to bottom, each sub-spray evaporation chamber 100 is in communication, the first sub-spray evaporation chamber 100 has a fluid inlet, and the last sub-spray evaporation chamber 100 has a gas outlet 103;

[0033] The sub-spray evaporation chamber 100 comprises at least two groups of fluid guiding assemblies 10, which are arranged in sequence in the sub-spray evaporation chamber 100, and form an S-shaped fluid passage in the sub-spray evaporation chamber 100, and the fluid flows in an S shape through the S-shaped fluid passage.

[0034] The spray evaporation cavity provided by the embodiment of the present application is used for the high-temperature gas from the air compressor to enter the spray evaporation cavity through the fluid inlet on the first layer of the sub-spray evaporation cavity 100, and the gas carries the liquid drops sprayed by the high-pressure nozzle, and the gas carrying the liquid drops firstly performs serpentine flow in the lower sub-spray evaporation cavity 100, and forms a cyclone between the fluid guiding components 10, and then enters the upper sub-spray evaporation cavity 100 to perform serpentine flow, and finally flows out of the spray evaporation cavity. With the flow, the high-temperature gas is cooled to the working temperature of the fuel cell, and the humidity is increased to the working range.

[0035] The spray evaporation cavity provided by the embodiment of the present application will be further explained and described below through optional embodiments.

[0036] It should be noted that only when the cooling and humidifying requirements of the high-temperature gas are met, and the low resistance is met, the membrane humidifier and the intercooler can be simultaneously replaced. For the cooling and humidifying requirements, the air should be kept in the limited volume for as long as possible. The spray evaporation cavity provided by the embodiment of the present application adopts a multi-layer structure, strengthens the fluid heat exchange, increases the length of the gas flow path, and forces the gas to form a cyclone between the fluid guiding components 10, greatly increases the residence time of the gas, and strengthens the heat exchange.

[0037] It should be noted that the layer interval plate 1 provided by the embodiment of the present application is at least one. When the layer interval plate 1 is one, the spray evaporation cavity is divided into two sub-spray evaporation cavities 100, the fluid enters the upper sub-spray evaporation cavity 100 after heat exchange in the lower sub-spray evaporation cavity 100, and is discharged after further heat exchange in the upper sub-spray evaporation cavity 100. A plurality of layer interval plates 1 can also be arranged according to requirements. At this time, the spray evaporation cavity is divided into a plurality of sub-spray evaporation cavities 100, and the gas is heat-exchanged in the plurality of sub-spray evaporation cavities 100, thereby prolonging the heat exchange path of the gas. In the case that the volume of the spray evaporation cavity is determined, the heat exchange area and the heat exchange time are increased by increasing the layer interval plate 1, but the volume of the spray evaporation cavity does not need to be increased, thereby reducing the occupied space of the spray evaporation cavity to the fuel cell.

[0038] Further, when the layer interval plate 1 is one, the first layer of the sub-spray evaporation cavity 100 has a fluid inlet, and the second layer of the sub-spray evaporation cavity 100 has a fluid outlet. When the layer interval plate 1 is a plurality, the first layer of the sub-spray evaporation cavity 100 has a fluid inlet, and the last layer of the sub-spray evaporation cavity 100 has a fluid outlet.

[0039] It should be noted that the layer interval plate 1 provided by the embodiment of the present application is horizontally arranged, that is, the spray evaporation cavity is divided into two parts from top to bottom. In this way, the water vapor heat-exchanged and evaporated in the next layer can continue to enter the previous layer to continue heat exchange, thereby improving the heat exchange efficiency.

[0040] In an alternative embodiment, the two groups of fluid guiding components 10 include a first group of fluid guiding components and a second group of fluid guiding components, the first group of fluid guiding components and the second group of fluid guiding components are arranged side by side;

[0041] The first group of fluid guiding components has a first fluid passage 101, the second group of fluid guiding components has a second fluid passage 102, and the first group of fluid guiding components and the second group of fluid guiding components form a third fluid passage 103; the first fluid passage 101, the second fluid passage 102, and the third fluid passage 103 form an S-shaped fluid passage.

[0042] It should be noted that the first group of fluid guiding components itself forms the first fluid passage 101, and the second group of fluid guiding components itself forms the second fluid passage 102. When the first group of fluid guiding components and the second group of fluid guiding components are arranged side by side, the third fluid passage 103 is formed between the first group of fluid guiding components and the second group of fluid guiding components.

[0043] In an alternative embodiment, the first group of fluid guiding components includes a first column of guiding fins 11 and a second column of guiding fins 12, the first column of guiding fins 11 and the second column of guiding fins 12 are arranged opposite to each other, and the first column of guiding fins 11 and the second column of guiding fins 12 form the first fluid passage 101.

[0044] For low pressure drop requirements, the embodiment of the present application designs a fin array group of the first column of guiding fins 11 and the second column of guiding fins 12, forcing the fluid to flow in a serpentine shape. The adjacent two fluid streams form a rotational flow, greatly reducing the resistance loss along the way and reducing the pressure drop.

[0045] In an alternative embodiment, the first column of guiding fins 11 is arranged at a first preset angle in the sub-spray evaporation cavity 100, and the second column of guiding fins 12 is arranged at a second preset angle in the sub-spray evaporation cavity 100, and the first preset angle and the second preset angle are complementary.

[0046] That is, the first column of guiding fins 11 and the second column of guiding fins 12 are arranged in different directions, the first column of guiding fins 11 is arranged at a first preset angle in the sub-spray evaporation cavity 100, for example, the first preset angle can be 45°, and the second column of guiding fins 12 is arranged at a second preset angle in the sub-spray evaporation cavity 100, for example, the second preset angle can be 135°. That is, the extension lines of the first column of guiding fins 11 and the second column of guiding fins 12 intersect, rather than being parallel, which shapes and limits the passing fluid to flow in a flow channel and communicate with other flow channels to form an S-shaped flow channel, the normal fluid flow path.

[0047] In an optional embodiment, the second row of drainage fins 12 further includes flow-limiting fins 121, which are located at the connecting head of the second row of drainage fins 12 and are used to restrict the fluid from flowing back to the current fluid channel through the next fluid channel or flowing to the previous fluid channel through the current fluid channel.

[0048] It is understandable that by setting the flow-limiting fin 121, the fluid entering the next fluid flow channel can be prevented from flowing back to the previous flow channel. The flow-limiting fin 121 is located at the connection head of the second row of guide fins 12. That is, when the fluid flows out of the first fluid flow channel and into the second fluid flow channel, due to the setting of the flow-limiting fin 121 at the connection head of the second row of guide fins 12, the fluid can only flow through the second fluid flow channel to the third fluid flow channel, and there will be no reverse flow.

[0049] Furthermore, at the beginning of each fluid channel, a flow-limiting fin 121 is provided to prevent the fluid from flowing back in the opposite direction, and at the end of each fluid channel, a flow-limiting fin 121 is provided to prevent the fluid from flowing ahead to the next flow channel.

[0050] Furthermore, in each group of fluid guide elements, a flow-limiting fin 121 is provided in the first row of guide fins 11 and the second row of guide fins 12. The flow-limiting fin 121 indicates whether the fluid is flowing in reverse or beyond the fluid channel. That is, the flow-limiting fin 121 is provided at the head of the first row of guide fins 11 in this fluid channel to prevent the fluid from flowing in reverse, i.e., flowing through this fluid channel to the next fluid channel; the flow-limiting fin 121 is provided at the tail of the second row of guide fins 12 in this fluid channel to prevent the fluid from flowing beyond the fluid channel, i.e., flowing through this fluid channel to the next fluid channel.

[0051] In one optional embodiment, the flow-limiting fin 121 includes a limiting portion and a flow-guiding portion connected together, the limiting portion and the flow-guiding portion being connected at a preset angle, the limiting portion being used to restrict fluid from flowing back into the current fluid channel through the next fluid channel.

[0052] See also Figure 2 The flow-guiding fins provided in the embodiments of the present invention all have the same shape. The flow-limiting fin 121 includes a limiting part that isolates the fluid flow channel from the adjacent fluid flow channel, preventing the fluid from flowing in reverse or not following the S-shaped path, and from flowing beyond the current fluid flow channel to the next fluid flow channel. Furthermore, the limiting part is connected to the spray evaporation chamber.

[0053] In an optional embodiment, the second set of fluid guiding elements includes a third row of guiding fins 13 and a fourth row of guiding fins 14, which are arranged opposite to each other, and a third fluid channel 103 is formed between the third row of guiding fins 13 and the fourth row of guiding fins 14.

[0054] It should be noted that the second set of fluid drainage components provided in this embodiment of the invention has the same structure and similar arrangement as the first set of drainage components.

[0055] Furthermore, in an optional embodiment, the third row of guiding fins 13 is arranged at a first preset angle within the sub-spray evaporation chamber 100, and the fourth row of guiding fins 14 is arranged at a second preset angle within the sub-spray evaporation chamber 100, with the first preset angle and the second preset angle being complementary.

[0056] In other words, the third row of guiding fins 13 and the fourth row of guiding fins 14 are arranged in different directions. The third row of guiding fins 13 is arranged at a third preset angle within the sub-spray evaporation chamber 100, for example, the third preset angle can be 45°. The fourth row of guiding fins 14 is arranged at a fourth preset angle within the sub-spray evaporation chamber 100, for example, the fourth preset angle can be 135°. That is, the extension lines of the third row of guiding fins 13 and the fourth row of guiding fins 14 intersect, rather than are parallel. This shapes and confines the passing fluid, causing it to flow within a flow channel and connect with other flow channels to form an S-shaped flow channel, the normal flow path of the fluid.

[0057] In an optional embodiment, the fourth row of drainage fins 14 further includes a flow-limiting fin 121, which is located at the connection head of the fourth row of drainage fins 14 and is used to limit the flow of fluid from flowing back to the current fluid channel through the next fluid channel or flowing to the previous fluid channel through the current fluid channel.

[0058] It is understandable that by setting the flow-limiting fin 121, the fluid entering the next fluid flow channel can be prevented from flowing back to the previous flow channel. The flow-limiting fin 121 is located at the connection head of the fourth row of flow-guiding fins 14. That is, when the fluid flows out of the third fluid flow channel and into the fourth fluid flow channel, due to the setting of the flow-limiting fin 121 at the connection head of the fourth row of flow-guiding fins 14, the fluid can only flow through the fourth fluid flow channel to the third fluid flow channel, and there will be no reverse flow.

[0059] Furthermore, in each group of fluid guide elements, a flow-limiting fin 121 is provided in the third row of guide fins 13 and the fourth row of guide fins 14. The flow-limiting fin 121 indicates whether the fluid is flowing in reverse or beyond the fluid channel. That is, the flow-limiting fin 121 is provided at the head of the third row of guide fins 13 in this fluid channel to prevent the fluid from flowing in reverse, i.e., flowing through this fluid channel to the next fluid channel; the flow-limiting fin 121 is provided at the tail of the fourth row of guide fins 14 in this fluid channel to prevent the fluid from flowing beyond the fluid channel, i.e., flowing through this fluid channel to the next fluid channel.

[0060] In one optional embodiment, each sub-spray evaporation chamber 100 is provided with a communication port 110 at the corner of the last set of fluid diversion components, and each sub-spray evaporation chamber 100 is connected through the communication port 110.

[0061] Furthermore, a fluid diversion assembly is also provided at the corner connection port 110, namely the first row of diversion fins 11 and the second row of diversion fins 12. The channel design between the layers of each sub-spray evaporation chamber 100, and the design of the diversion fins and the layer partition plate 1 between the channels, ensure the flow between the layers of the sub-spray evaporation chamber 100 and the serpentine flow within the layers.

[0062] In an alternative embodiment, the last layer of sub-spray evaporation chamber 100 has a fluid outlet, which includes a spray inlet 104 and a gas inlet 105.

[0063] Further, see Figure 2 When there is one partition plate 1, the spray evaporation chamber is divided into two sub-spray evaporation chambers 100. The lower sub-spray evaporation chamber 100 is provided with a spray inlet 104 and a gas inlet 105, and the upper sub-spray evaporation chamber 100 is provided with a gas outlet 103.

[0064] Further, see Figure 3 In this embodiment of the invention, the gas outlet 103 of the spray evaporation chamber is connected to the fuel cell stack. That is, high-pressure air from the air compressor enters the spray evaporation chamber, and high-pressure coolant is provided by a high-pressure water pump. After heat exchange in the spray evaporation chamber, the air directly enters the fuel cell stack from the gas outlet 103.

[0065] On the other hand, a system with a spray evaporator chamber having the functions of a humidifier and an intercooler is provided. The system includes any of the spray evaporator chambers with the functions of a humidifier and an intercooler as described above. The system also includes an air compressor, the outlet of which is connected to the air inlet of the spray evaporator chamber.

[0066] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
