Test fixture for fuel cell membrane electrode

Abstract

The invention relates to a test fixture for a fuel cell membrane electrode. The test fixture comprises a frame, a single cell assembly, a pressing assembly, a gas conveying assembly and a detection assembly, a containing cavity is formed in the frame, and the bottom of the containing cavity is horizontal. The single battery assembly comprises a first polar plate and a second polar plate, the first polar plate is horizontally arranged at the bottom of the accommodating cavity, the second polar plate is detachably mounted at the upper end of the first polar plate, the pressing assembly comprises a pressing mechanism and a pressure detector, and the pressure detector is used for detecting pressing force; the detection assembly is connected with the single battery assembly, and the gas conveying assembly is connected with the single battery assembly; a temporary single battery is formed between a first polar plate and a second polar plate, and the first polar plate and the second polar plate are pressed by a pressing assembly with a pressure detector, so that the assembling pressure value of the temporary single battery can be monitored and displayed in real time, and the pressed state of a membrane electrode can be quickly known; the influence of the assembly pressure of the temporary single battery on the performance of the membrane electrode can be accurately obtained, so that the test result is more accurate.
