Abstract
A bipolar plate is provided that includes a metal plate, at least one channel, a first coating, and a second coating. The metal plate has a first surface, a second surface opposite the first surface, a first edge surface connecting the first surface to the second surface, and a second edge surface opposite the first edge surface and connecting the first surface to the second surface. The at least one channel is formed in at least one of the first surface and the second surface. The first coating is formed on the at least one of the first surface and the second surface such that the first coating covers each of the at least one channel. The second coating is formed on the first edge surface and the second edge surface. Each of the at least one channel has a semi-circular shape and extends along the at least one of the first surface and the second surface.
