Method and device for in-situ determination of proton membrane attenuation in membrane electrode

The invention discloses a method and a device for in-situ determination of proton membrane attenuation in a membrane electrode. According to the method, a to-be-measured proton membrane is used as a fake membrane electrode without a catalytic layer to be assembled into a single cell, then a fuel cel...

description	The invention discloses a method and a device for in-situ determination of proton membrane attenuation in a membrane electrode. According to the method, a to-be-measured proton membrane is used as a fake membrane electrode without a catalytic layer to be assembled into a single cell, then a fuel cell short stack of a complete membrane electrode is used as an object of a synchronous measurement experiment, and the actual working condition of the proton membrane in the fuel cell operation process is obtained through actual operation of the short stack in the measurement process. Then controlling the temperature of the single cell according to the temperature of the short stack, controlling the voltage of the single cell according to the voltage of the short stack, controlling the gas back pressure of the single cell according to the gas back pressure of the short stack, and inputting water generated in the actual operation process of the short stack into the cathode of the single cell; in other words, the proto
