Abstract

This paper reviews bipolar plate materials and coatings for polymer electrolyte fuel cell. First, six roles and 10 requirements of the bipolar plate are described in detail. Secondly, type of materials for the bipolar plate and their advantages and disadvantages are mentioned. Thirdly, different metallic materials are introduced in terms of electrical and thermal conductivities, corrosion resistance, weight, strength and cost. Finally, various types of coating materials and methods were briefly reviewed.
