Abstract
A fuel cell includes a membrane electrode assembly and an anode side metal separator and a cathode side metal separator sandwiching the membrane electrode assembly. An oxygen-containing gas flows in an oxygen-containing gas flow field in a horizontal direction. A coolant flows in a coolant flow field in a vertical direction. The coolant flow field is connected to coolant supply passages and coolant discharge passages. The opening of one of the coolant supply passages and the opening of one of the coolant discharge passages are smaller than those of the other coolant supply passages and the other coolant discharge passages in cross section, respectively. Thus, the flow rate of the coolant supplied to an area near outlets of the oxygen-containing gas flow field and the fuel gas flow field become smaller than the flow rate of the coolant supplied to the other area.
