METHOD AND DEVICE FOR DETECTING PILE CONSISTENCY OF PROTON EXCHANGE MEMBRANE FUEL CELL

摘要

A method for detecting the fluid distribution consistency of a proton exchange membrane fuel cell pile (620). The proton exchange membrane fuel cell pile (620) consists of more than two sequentially stacked single cells. The proton exchange membrane fuel cell pile (620) comprises an anode inlet and a cathode inlet. A gas mixed with hydrogen and an inert gas is introduced into the anode inlet or the cathode inlet of the proton exchange membrane fuel cell pile (620), a same voltage used for hydrogen oxidation is applied to two electrodes of each cell of the proton exchange membrane fuel cell pile (620), and the fluid distribution consistency of the proton exchange membrane fuel cell pile (620) is determined by testing and comparing oxidation currents In of each single cell. Compared with the prior art, the method for detecting the fluid distribution consistency and the pile consistency of the proton exchange membrane fuel cell (620) is simple and easy to implement, the detection device is simple and easy to assemble, and the detection method and the detection device are of great significance to accurate detection of performance of each cell of the proton exchange membrane fuel cell pile (620).
