Abstract
A polymer electrolyte fuel cell comprises a plurality of stacked cells each having an ionic conductive electrolyte membrane, an anode placed on one side of the electrolyte membrane, a cathode placed on the other side of the electrolyte membrane, and a conductive separator on which a first refrigerant channel for flow of a refrigerant is formed in center part thereof. The separator comprises penetration holes constituting a manifold which extend in a direction of stacking of the plurality of cells and through which the refrigerant flows and second refrigerant channels for communication between the penetration holes and the first refrigerant channel. A plurality of protrusions that protrude into the penetration holes from parts of wall surfaces of the penetration holes that are located peripherally in connection parts between the penetration holes and the second refrigerant channels.
