Progress of bipolar plates for proton exchange membrane fuel cells

Abstract

The basic structure of proton exchange membrane fuel cell mainly consists of bipolar plates, diffusion layer, catalyst layer and proton exchange membrane, of which the bipolar plates are the most important components. In recent years, composite bipolar plates have become the focus of bipolar plate material research because they combine the advantages of graphite bipolar plates and metal bipolar plates. Therefore, this review explains the development of composite bipolar plates in recent years in a clearer way by sorting out and analysing the pairing of different carbon and resin materials, which will be helpful for bipolar plate development.
