Abstract
The electrical resistance in PEMFC will reduce the performance of the fuel cell stack. The electrical resistance includes the bulk resistance of the components and the contact resistance between the components, the latter has larger influence on the performance of the fuel cell than the former.   The contact resistance is mainly determined by the clamping pressure. In this paper, we first investigate the relation between the clamping pressure and the contact resistance, then we use some kind of functions to represent the relation. According to the relation, we can predict the contact resistance with FEM software, and investigate the effects of the contact pressure distribution on the contact resistance. We find that the contact resistance is affected by clamping pressure significantly, but lightly affected by the pressure distribution, though the uniform distribution could decrease the contact resistance.   In addition, the uniform distribution can improve the managements of heat, water and the transportation of the fuel. So we design the clamp endplate of the stack to provide the uniform pressure distribution. We use the standard deviation of the pressure to judge the uniformity of the pressure distribution using newly designed endplate and compare with the traditional one. The results show that the new endplate give more uniform pressure distribution than traditional endplate, and could be lighter after simple weight reduction.
