Problems solved by technology

[0005] For the first type of device, considering the water separation efficiency, the gas-liquid mixture needs to form a sufficiently large vortex and centrifugal force, so the size of the water separator is relatively fixed and the volume is large, which is not conducive to improving the layout and integration applicability of the water separation device and the system Volume power density
For the second type of device, the flow resistance is too large, which leads to an increase in the performance requirements of the circulation device; under the action of long-term gas flushing, the internal material may fall off, block the flow channel, and seriously affect the performance of the fuel cell

no. 1 Embodiment

[0056] The first specific embodiment of the present invention provides a water separator.

[0057] see Figure 1 to Figure 3 , figure 1 A sectional view of the water separator provided for the first specific embodiment of the present invention; figure 2 A sectional view of the first water diversion section provided for the first specific embodiment of the present invention; image 3A cross-sectional view of the water diversion section at the tail provided for the first specific embodiment of the present invention.

[0058] The water separator provided by the first specific embodiment of the present invention includes a first water diversion section 1 and a tail water diversion section 2, wherein:

[0059] a) The head water diversion section 1 includes the head main flow pipe 11 and the head drainage pipe 12 . Both ends of the head main flow pipe 11 are respectively provided with a mixed fluid inlet 111 and a head fluid outlet 112 . The first drainage pipe 12 includes a f...

no. 2 Embodiment

[0079] The second specific embodiment of the present invention provides a water separator.

[0080] see Figure 4 to Figure 6 , Figure 4 A cross-sectional view of the water separator provided for the second specific embodiment of the present invention; Figure 5 A cross-sectional view of the middle water-cutting section provided for the second specific embodiment of the present invention; Figure 6 It is a schematic diagram of the overall structure of the water separator provided in the second specific embodiment of the present invention.

[0081] The only difference between the water separator provided by the second specific embodiment of the present invention and the water separator provided by the first specific embodiment of the present invention is that the water separator provided by the second specific embodiment of the present invention is different from that provided by the first specific embodiment. On the basis of the water separator, an intermediate water diver...

no. 3 Embodiment

[0088] The third specific embodiment of the present invention provides a water separator.

[0089] The difference between the water separator provided by the third specific embodiment of the present invention and the water separator provided by the second specific embodiment of the present invention is only that: a plurality of intermediate water diversion sections are arranged in series in sequence, and the middle of the multiple intermediate water diversion sections The main flow pipes are connected at the ends in sequence, and the connecting pipe sections in the multiple intermediate water diversion sections are connected at the ends in sequence. For details, see Figure 4 , the water separator provided by the third specific embodiment of the present invention, in Figure 4On the basis of this, multiple intermediate water diversion sections 3 are arranged in parallel.

[0090] Wherein, in the middle water diversion section 3 at the head end, the middle fluid inlet 311 of ...

Abstract

The invention discloses a water segregator and a fuel cell, the water segregator comprises a head water dividing section and a tail water dividing section, the head water dividing section comprises ahead main flow pipe and a head drainage pipe, and the head drainage pipe can reversely drain and output gas separated from the head main flow pipe; the tail water distribution section comprises a tailmain flow pipe and a tail drainage pipe, and the tail drainage pipe can conduct reverse drainage on gas separated out of the tail main flow pipe and output the gas. According to the water segregator,liquid drops and gas in a gas-liquid mixture are separated through inertia force, good water segregation efficiency can be guaranteed, and the technical problems in the prior art that the device is large in size, large in flow resistance and the like are solved. Furthermore, the water segregator can be arranged to be of a multi-stage flexible structure so that the applicability of the water segregator is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a water separator and a fuel cell provided with the water separator. Background technique [0002] The existing water separators for fuel cells can be divided into two categories based on basic principles: [0003] (1) Centrifugal force is used to separate liquid droplets, and guide vanes, or baffle structures, or spiral flow channels are used in the water separator to induce the gas-liquid mixture to rotate at high speed, and the liquid droplets are thrown to the water separator under the action of centrifugal force The inner wall of the device and flow down to achieve the purpose of separation from the gas; [0004] (2) Utilize the droplet adhesion, adopt filter element or corrugated plate and other structures to increase the contact area between the droplet and the surrounding wall surface, so that the droplet adheres to the wall surface and achieves the purpose of separat...
