Abstract
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.
