Abstract
Abstract Gas delivery plates are key components for a Proton Exchange Membrane (PEM) fuel cell. The unique functions of these plates impose special requirements on their strength, conductivity and electro-chemistry stability. Cost reduction of these plates can greatly facilities the commercialization of PEM fuel cell, the promising zero emission power plant for the future. In this work, a virtual prototyping study on PEM fuel cell gas delivery plate is carried out. Solid modeling and mathematical modeling are used to form virtual prototypes of the gas delivery plates. Computational fluid dynamic (CFD) analysis and nonlinear finite element analysis (FEA) on plate structure and flow field properties are used to test the performance of the designed plates and to guide the design optimization. The research focuses on the new fuel cell plate designs that use polymer composite material to form flow field channels. The method of virtual prototyping based design optimization is discussed using a real fuel cell plate design example. This study provides guidelines to fuel cell plate development and demonstrates a new design approach.
