Abstract:

As a new on?board power source, proton exchange membrane fuel cell (PEMFC) has come under the spotlight due to its wide application prospect. Flow field plate is one of the core components of PEMFC, which plays the role of distributing reaction gas, removing moisture and impurities and conducting electrons. At present, most of the research on the flow field of PEMFC has focused on the optimizations of the size of routine flow channel and the layout of flow field, while some studies add different forms of blocks in the flow channel to enhance gas mass transfer, or apply porous materials to flow field plate, or design a new 3D mesh flow field structure to optimize the thermal management of water in fuel cell and intensify the effects of mass transfer for enhancing the performance of PEMFC. These researches are summarized with a few conclusions drawn in this paper.

Key words: PEM fuel cells, flow field optimization, mass transfer enhancement
