    摘要： The present invention provides a fuel cell stack including a plurality of unit cells laid one upon another. Each of the unit cells includes an electrolyte, a pair of electrodes that are arranged across the electrolyte and respectively have a catalytic reaction layer, and a separator having means for feeding a supply of gaseous fuel to one of the electrodes and a supply of oxidant gas to the other of the electrodes. The separator is a laminate including a gas-tight conductive plate A and another conductive plate B having at least one slit, which continuously meanders from one end to another end of the conductive plate B. The technique of the present invention gives a compact fuel cell stack assembled by a simple process.
