Abstract

The flow field design is considered an important factor affecting the power density and operational stability of proton exchange membrane fuel cell (PEMFC). In this research, a two-step flow field optimization method is proposed to improve mass transfer, water management and output performance, which combines improved topology optimization algorithm with customization design methods. In this study, a joint computational model is established to explore the effects of different channel structures on the internal reactants distribution and performance of PEMFC. Comprehensive analysis is conducted on traditional serpentine flow field, parallel flow field, and dot matrix flow field. The results show that the two-step optimization method increased the average current density by a maximum of 10.44 % compared with the traditional flow fields. Moreover, the bipolar plate mass had been reduced by a maximum of 12.3 %. The flow fields optimization methods would provide a reference for bipolar plate design.
