质子交换膜燃料电池电堆反复装配的电阻补偿设计研究
Design of compensation for repeated assembly of proton exchange membrane fuel cell stacks
摘要
Abstract
Repeated assembly of proton exchange membrane fuel cell(PEMFC)stacks causes assem-bly force change and output performance degradation.In this study,a cyclic compression experiment was conducted to investigate the effects of cyclic compression on the mechanical property,body resis-tance and contact resistance of the gas diffusion layer,and a compression rate compensation scheme for different assembly times was proposed.It is found that,with the same compression rate,the pres-sure and thickness attenuation of the gas diffusion layer mainly occur in the second assembly,with a pressure attenuation of 6.24%and a thickness reduction of 4.64%.In addition,the body resistance and contact resistance of the gas diffusion layer are enhanced by 2.82%and 7.77%,respectively.Hence,an assembly compensation scheme was designed using the satisfaction function to obtain the compression rate interval and the optimal compression rate at different assembly times,which can provide a reference for the optimization of the assembly quality of the PEMFC stack.关键词
