摘要： A fuel cell is obtained, in which oxidation degradation of a catalyst in the cathode can be prevented even if a large volume of air instantaneously penetrates into the cell, and the fuel-cell characteristics also do not deteriorate even though starting-up, shutting-down and pausing operations are repeatedly performed. As a method of controlling a fuel cell system, hydrogen-containing fuel gas is supplied to the anode and oxidant gas is supplied to the cathode, an external load is connected between the anode and the cathode so that the fuel cell generates electric power, the external load is disconnected after the power generation, a resistor is connected between the anode and the cathode, supply of the oxidant gas is stopped, and then supply of the fuel gas is stopped after the potential at the cathode has dropped to equal to or lower than the potential at which hydrogen evolution starts, so as to pause the fuel cell.

摘要： A fuel cell includes a solid polymer electrolyte membrane and cathode and anode catalyst layers held between a fuel electrode substrate having a surface area larger than that of the cathode catalyst layer and an oxidizer electrode substrate having a surface area larger than that of the anode catalyst layer. The fuel electrode substrate includes a fuel-sealing support portion surrounding the cathode catalyst layer. The oxidizer electrode substrate includes an oxidizer-sealing support portion surrounding the anode catalyst layer. The fuel-sealing and oxidizer-sealing support portions each include pores partially or wholly filled with a resin. The fuel-sealing support portion is bonded to the membrane by the resin at a position closer to an outer edge of the membrane than is the cathode catalyst. The oxidizer-sealing support portion is bonded to the membrane by the resin at a position closer to the outer edge of the membrane than is the anode catalyst.

摘要： A method of operating a fuel cell including a fuel electrode, an oxidant electrode, and an electrolyte layer having hydrogen ion conductivity sandwiched between the fuel electrode and the oxidant electrode, so that the fuel cell generates electricity as a result of an electrochemical reaction between a fuel and an oxidant. Each time the fuel cell is started from a non-operating condition, the fuel is supplied to the fuel electrode with the fuel electrode and the oxidant electrode electrically interconnected to produce hydrogen at the oxidant electrode by provoking electrochemical reactions expressed by the chemical equations H2→2H++2e− and 2H++2e−→H2 at the fuel electrode and the oxidant electrode, respectively, reducing oxides on the oxidant electrodes using the hydrogen produced at the oxidant electrode. Then the oxidant is supplied to the oxidant electrode to begin normal continuing operation of the fuel cell.

摘要： There is obtained a fuel cell which has stable characteristics and produces high voltage/high output. The fuel cell uses a laminate in which single cells each including an anode, a cathode, and an electrolyte film sandwiched therebetween are sequentially stacked on each other through a separator plate. Fuel flow channels and oxidant flow channels are provided in the separator plate, and communicating holes are provided at the midway portion thereof. The flow channels in the separator plate communicate, through the communicating holes, with the flow channels in another separator plate through which the same kind of gas flows so that the same kind of gases flow into each other.

摘要： The long side of a rectangular first separator plate of a fuel cell is divided into n equal area smaller rectangular parts so that the long sides of the rectangular parts are not larger than 2½ and not smaller than ½½ the length of the short sides. Through holes pass through a stack of plates substantially at centers of the smaller rectangles. Bolts having an annular elastic member at one end pass through the through holes, and the stack is clamped together.
