摘要
Firstly, new designed high temperature polymer electrolyte membrane fuel cell (HTPEM) with 1 cm2 active area is introduced, and the experimental condition such as the optimum gas flow rate and the appropriate temperature are obtained. Then combining the cross-cutting schematic diagram of the original thickness for each component of the MEA, the cell assembly torque with different thickness sealing gaskets is systematically studied, which not only provides a reference for improving cell performance, but also obtains the optimal gasket thickness and torque fit range. Finally, by designing a pressure device, the thickness and volume of various components or materials of the membrane electrode assembrane (MEA) are tested as pressure changes, and the feasibility of establishing the mechanical model is verified. The reason why the torque affects the HTPEM performance is explained from the inside of the cell.
