    摘要： A fuel battery system of the present invention includes: an alkaline fuel battery; a fuel supply device for supplying a fuel to an anode of the fuel battery; an oxidizing agent supply device for supplying an oxidizing agent to a cathode of the fuel battery; a liquid supply device which supplies a liquid to the cathode; a valve which switches between fluids to be supplied to the cathode; and a control device which controls the switching of the valve. The fuel battery system suppresses the neutralization of an anion-exchange electrolyte due to carbon dioxide in the air, by supplying the liquid from the liquid supply device to the cathode and making the cathode in the state of being immersed in the liquid when the fuel battery stops power generation.

    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.
