Carbon paper compression drainage test tool for hydrogen fuel cell

Abstract

The present invention relates to a hydrogen fuel cell carbon paper compression drainage test tool, which comprises an upper module, a lower module, a fastening bolt and a nut, the fastening bolt sequentially passes through the guide holes of the lower module and the upper module and then is connected with the nut to mutually fix the upper module and the lower module, and the lower surface of the upper module is provided with a flow channel structure. A water inlet, a water outlet, an air vent and a pressure test port which are communicated with the runner structure are formed in the top surface or the side surface of the upper module, the runner structure is close to the first observation end of the upper module, a placement groove corresponding to the runner structure in position is formed in the upper surface of the lower module, and one side edge of the placement groove extends to the second observation end of the lower module; the first observation end and the second observation end jointly form a test observation window, and a transparent protection plate is arranged on the outer side of the observation window. Compared with the prior art, direct observation of drainage conditions of the carbon paper under different compression ratios is realized, subsequent design and selection of the hydrogen fuel cell are facilitated, the design cost is effectively reduced, and the research and development period is shortened.

Description

technical field [0001] The invention relates to the field of hydrogen fuel cells, in particular to a carbon paper compression drainage test tool for hydrogen fuel cells. Background technique [0002] In the design of hydrogen fuel cells, different membrane electrode carbon papers need to be selected according to different hydrophobic properties, and the same membrane electrode carbon paper has different drainage conditions under different compression rates. At present, the selection of membrane electrode carbon paper is usually selected by experience, and then the actual performance test is carried out in the sample, which leads to high design cost and long cycle. Therefore, the market lacks a device that can directly test the drainage condition of the membrane electrode carbon paper under different compression ratios. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a carbon paper compression and drainage test tool for hydrogen fuel ce...
