Description

Technical Field

[0001] The present application relates to the field of fuel cell systems, and in particular to a combinable replacement filter element, a deionization device, and a fuel cell system. Background Art

[0002] As a clean, environmentally friendly and efficient energy conversion device, fuel cells are increasingly valued by various countries as fuel cell technology gradually matures, especially in my country, where they have achieved rapid development and their application scope is becoming wider and wider. Proton exchange membrane fuel cells (PEMFC) have the advantages of environmental protection, high efficiency, fast startup speed and high power density. They are one of the main competitors of future transportation power systems. When hydrogen and oxygen in the air undergo electrochemical reactions to generate electricity through proton exchange membranes under the action of catalysts, in order to improve power generation efficiency, the air is usually compressed. The main purpose is to increase the concentration of oxygen so as to achieve more contact opportunities between hydrogen and oxygen under limited reaction volume, thereby improving reaction efficiency. The current fuel cell engine system is usually equipped with an air filter, an air compressor, an intercooler, and a membrane humidifier. The air passes through the above components in turn, and then is filtered, compressed, cooled, and humidified before entering the stack. The existing fuel cell system is large in size, consumes a lot of power, greatly increases the system burden, increases cost, and is seriously wasteful. The nitrogen content in the air that does not participate in the reaction is too high, which increases the burden on the intercooler and humidifier. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] The present application provides a combinable replaceable filter element, a deionization device and a fuel cell system, which are described in detail below.

[0034] See also Figure 1-Figure 7 A combinable replaceable filter element 10 is disclosed. The filter element 10 comprises a core body 100 and an upper cover 101 and a base 102 arranged at two ends of the core body 100 .

[0035] More specifically, in the present embodiment, the core body 100 and the base 102 are integrally injection molded, and the core body 100 is a cylindrical structure having a plurality of reinforcing ribs 1000 arranged along the direction of the core body 100, and a core filter 1001 is integrally arranged on the reinforcing ribs 1000. Similarly, the same reinforcing ribs 1000 and core filter 1001 are also arranged on the integrally injection molded base 102; of course, in some other embodiments, a separate arrangement may be adopted between the core body 100 and the base 102 to ensure good sealing between the two.

[0036] More specifically, a sealing groove 1002 is provided on the core body 100. The sealing groove 1002 is basically circumferentially arranged in a direction surrounding the core body 100. A plurality of sealing grooves 1002 can be provided, and a sealing rubber ring 1003 is provided on the sealing groove 1002. The sealing rubber ring 1003 can be provided on only any one of the plurality of sealing grooves 1002, and there is no need to provide the sealing rubber ring 1003 on all the sealing grooves 1002. By fixing the sealing rubber ring 1003 on different sealing grooves 1002, different performances of the deionization device 20, such as a high deionization rate or a low flow resistance function, can be achieved.

[0037] An upper cover 101 is provided above the core body 100 and is closed after the filter material is filled. Taking the present embodiment as an example, the closing method is that a closing portion 1015 is provided at the lower edge of the annular structure of the upper cover 101. The closing portion 1015 of the present embodiment adopts welding ribs, which are connected to the core body 100. The upper cover 101 is welded to the core body 100 through the welding ribs. In other embodiments, the closing portion 1015 can also be closed by processes such as a threaded structure and an adhesive structure.

[0038] More specifically, the upper cover 101 is an annular structure, and a support rib 1010 is arranged on the annular structure. The support rib 1010 is annular and radial. An upper cover filter 1011 is integrally arranged on the support rib 1010. A convex column 1012 is arranged above the upper cover 101. The convex column 1012 of the upper cover 101 is arranged on the support rib 1010. A positioning groove 10120 is arranged on the convex column 1012. The positioning groove 10120 matches the positioning column 1020 on the base 102. The positioning column 1020 can be embedded in the positioning groove 10120 to achieve the combined use or replacement of two or more filter elements 10 (10') of different sizes and models. A groove 1014 is arranged above the annular center of the annular structure of the upper cover 101, and an elastic positioning block 1013 is arranged on the groove 1014 to adjust the height of the combined filter element 10.

[0039] This combined core-changing design greatly improves the universality of the deionization device 20, reduces the cost of mold development, and increases the freedom of fuel cell system integration. The replaceable core design can also save users' lifetime use costs. The filter element 10 can be recycled to reduce environmental pressure.

[0040] This embodiment provides a deionization device 20, such as Figure 7 As shown, the deionization device 20 at least has a barrel 200 and end caps 201 arranged on both sides of the barrel 200. The structure of the deionization device 20 can be the same as that of the existing deionization device, which will not be described in detail here; a combinable replacement filter element 10 is arranged in the barrel 200. According to the different models and specifications of the deionization device 20, the combinable replacement filter element 10 in the barrel 200 is used alone, or two or more are used in combination; due to the combinable characteristics of the filter element 10 and the elastic positioning block 1013 and the sealing rubber ring 1003 arranged thereon, the height and width can be adjusted, so it can be adapted to deionization devices 20 of various models and specifications. The filter element 10 can be replaced separately by opening the upper end cap 201.
