Abstract

The use of metals as a material for bipolar plates in proton exchange membrane (PEM) fuel cells offer a number of advantages in comparison with other materials. Several companies and institutes are currently working on the development of such bipolar plates and have patented their results. Whereas in the production of metallic bipolar plates there are no major obstacles, there are still some issues to be solved concerning corrosion and conductivity of these plates in the fuel cell environment. Up to now, the method of solving these issues seems to be to coat the plates with materials which prevent corrosion and growth of oxide layers with a high resistivity. The requirements for these bipolar plates and their current status is outlined in the chapter.
