Abstract Different types of staggered variable-diameter flow field structure have been analyzed by computational fluid dynamics software COMSOL Multiphysics to investigate the effects of throttling width and throttling length ratio on mass transfer and performance of proton exchange membrane fuel cell. The results show that proper throttling width and throttling length ratio can significantly improve uniformity of oxygen concentration distribution which results in an improved output performance, and the water removal is enhanced as well.
