A polymer electrolyte fuel cell comprises: a cell stack of a plurality of unit cells, each of the unit cells comprising a hydrogen-ion conductive polymer electrolyte membrane, an anode and a cathode sandwiching the polymer electrolyte membrane, an anode-side separator having a gas flow channel for supplying a fuel gas to the anode, and a cathode-side separator having a gas flow channel for supplying an oxidant gas to the cathode; a pair of current collector plates that sandwiches the cell stack; and a pair of end plates that clamps the cell stack and the current collector plates under pressure. The current collector plates comprise a conductive carbon material as a main component, and have a terminal section for connecting a power output cable in the vicinity of an inlet-side manifold for the fuel gas or the oxidant gas.
