Proton exchange membrane fuel cell (PEMFC) has high power density and energy conversion efficiency. Bipolar plate is one of the key components of the proton exchange membrane fuel cell, not only affects the performance of the battery, but also affects the cost of the battery, which is become a bottlenecks. This paper introduces several common forms of the bipolar plate flow channel of the PEMFC, analyzes their advantages and disadvantages, and then some new type of flow channel type comes up after improvements on this basis, so the future development trend of fuel cells summed up is combined with bionics or using a complex flow field. An overview of the commonly used material and processing of the bipolar plate, respectively, graphite sheet, sheet metal and composite bipolar plates.
