摘要： Disclosed is a fuel cell in which a membrane electrode assembly less undergoes increase in ion conduction resistance, and a polymer electrolyte membrane less undergoes deterioration. Specifically, the polymer electrolyte membrane includes a first membrane and a second membrane being two different membranes composed of polymer electrolytes having different ion-exchange capacities, in which the first membrane has an area of one surface thereof equal to or larger than an area of one surface of an anode or a cathode, and the second membrane has an area of one surface thereof smaller than that of the first membrane and is arranged in a gas inflow region on a side being in contact with the cathode. The second membrane has an ion-exchange capacity smaller than that of the first membrane or has a number-average molecular weight larger than that of the first membrane.
