Abstract

A fuel cell includes an anode separator and a cathode separator each including a coating on its surface. Each of the anode and cathode separators includes: a body; a coolant manifold configured to allow a coolant to flow therethrough; an intra-cell sealing portion that provides a seal between the anode and cathode separators within the fuel cell and that is provided by the body being bonded to the insulating sheet so as to surround the coolant manifold; and a sacrificial electrolytic corrosion portion disposed between the coolant manifold and the intra-cell sealing portion and including a plurality of exposed portions where a base material is exposed without being covered with the coating. The sacrificial electrolytic corrosion portion includes at least one of the exposed portions on a straight line connecting the coolant manifold and the intra-cell sealing portion.
