A fuel cell is a device that converts chemical potential energy into electrical energy. Proton Exchange Membrane (PEM) is one specific fuel cell technology that is highly suited to automotive applications due to its energy conversion efficiency and package compactness.
Bipolar plates constitute one of the most important parts of a PEM fuel cell stack with multifunctional character. It distributes fuel gas and oxygen over the whole active surface area, joins together the anode of one cell to the cathode of another, pro–vides electrical conduction between cells, facilitates fluid management within the cells, removes heat from the active areas, among others.
Cost and material choices of bipolar plates have long been the bottlenecks for further development and application of PEM fuel cells, as bipolar plates represent 2nd largest portion of cost in a fuel cell stack. Vigorous efforts have been made to evaluate different materials and manufacturing processes in order to meet the demanding expectations for the plates.
