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.

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.

A polymer electrolyte fuel cell comprises a main stack alternately stacked with cells each provided with gas-diffusing electrodes on both sides of an ion-conducting electrolyte membrane and gas separators for supplying fuel to one of the electrodes and oxidant gas to the other electrode on each of the cells, and an auxiliary stack alternately stacked with the cells and the gas separators, the auxiliary stack having a lesser number of cells and gas separators than the main stack and having an independent current path from the main stack, wherein fuel and oxidant gas are supplied to the main stack after passing through the auxiliary stack, and wherein the load on the auxiliary stack is controlled. The load on the auxiliary stack is additionally controlled such that the electric potential of the fuel electrodes of the auxiliary stack exceeds the electric potential of the oxidation of carbon monoxide, whereby the voltage per layer of cell in the auxiliary stack continuously oscillates.
