    摘要: A fuel cell device, wherein, after an output voltage from a main body of a fuel cell is converted using a converter, the relation between the resultant predetermined output voltage V 1 and an output voltage V 2 from a secondary battery is so set as to satisfy V 1>V 2. When, at the time of a sudden change of an external load, the output voltage V from the main body of the fuel cell becomes lower than a predetermined voltage V 3, an output to a charge controlling unit is stopped. When the output voltage V from the main body of the fuel cell is lowered even further and becomes lower than a predetermined voltage V 4, an output to an auxiliary device, which is necessary for driving the fuel cell device, is switched from the output from the converter to the output from the secondary battery.

    摘要: A polymer electrolyte fuel cell having a large economical advantage uses a gasket which includes an elastomer layer that is inexpensive, highly resistant to chemicals, particularly to acids, and exhibits a high sealability. The elastomer layer is provided with an adhesive layer, and the gasket is both easy to position and easy to assemble. The fuel cell includes unit cells each including a positive electrode, an electrolyte plate, and a negative electrode, and gaskets each arranged at the circumferential part of the unit cell alternately stacked via a separator placed therebetween. The gasket includes an elastomer layer and an adhesive layer, with the elastomer layer being adhered to at least one side of the separator via the adhesive layer.

    摘要: A gas diffusion layer including an electroconductive porous material and 16-55% by weight of fluororesin added to the electroconductive porous material is used for at least one of the positive electrode and the negative electrode of a membrane/electrodes assembly of a polymer electrolyte fuel cell. As a result, the water-retaining property of the inside of the membrane/electrodes assembly is improved without hindering gas diffusion, thus enabling polymer electrolyte to be moistened with water formed at the positive electrode, and thereby providing a polymer electrolyte fuel cell which operates by using unhumidified gas.
