Problems solved by technology

At present, the selection of membrane electrode carbon paper is usually based on empirical selection, and then the actual performance test is carried out in the fuel cell, resulting in higher design costs and longer cycles.
Therefore, the market lacks a device that can directly test the IP air permeability of membrane electrode carbon paper

Abstract

The invention relates to a carbon paper IP air permeability testing tool for a fuel cell, which comprises a lower bottom plate, an upper cover plate, two side plates and filler gauges, the center of the top surface of the lower bottom plate is a carbon paper placing surface, two sides of the carbon paper placing surface are provided with two lower vent grooves, the outermost two sides of the top surface of the lower bottom plate are filler gauge placing surfaces, the center of the bottom plate of the upper cover plate is a carbon paper pressing surface, two upper vent grooves are formed in the two sides of the carbon paper pressing face, filler gauge pressing faces are arranged on the two outermost sides of the top face of the lower bottom plate, the lower bottom plate and the upper cover plate are folded up and down to form a pressing module, the upper vent grooves and the lower vent grooves are folded to form two vent pipe holes, and a sealing unit is arranged in a gap close to the filler gauge side. The two side plates are installed on the two sides of the pressing module in a sealed mode respectively, and each side plate is provided with a gas inlet and a gas outlet. Compared with the prior art, the carbon paper IP air permeability testing tool for the fuel cell has the advantages that the IP air permeability of the carbon paper is directly tested, the operation is simple and convenient, and the subsequent design and selection of hydrogen fuel cells are facilitated.

Description

technical field [0001] The invention relates to the field of fuel cell design and testing, in particular to a carbon paper IP air permeability testing tool for fuel cells. Background technique [0002] In the design stage of hydrogen fuel cells, the selection of membrane electrode carbon paper is very important. One of the key factors for selection is the IP (In Plane) air permeability of carbon paper. This parameter is used to characterize the performance of carbon paper, which can be used To evaluate the air permeability of carbon paper. The use of carbon paper with good air permeability can significantly improve the drainage under the ridge of the fuel cell, accelerate mass transfer, and improve the performance of the battery. At present, the choice of membrane electrode carbon paper is usually selected empirically, and then the actual performance test is carried out in the fuel cell, resulting in higher design cost and longer cycle time. Therefore, the market lacks a d...
