NOVELTY - Electrolyte electrode assemblies (26) and separators (28) are alternately stacked to form a fuel cell stack. The separator has a fuel gas channel (76) divided by a partition (77) into a first fuel gas channel unit (76a) having a fuel gas inlet (48) for supplying fuel gas before consumption from fuel gas supply passage (36) to fuel gas flow field (45), and a second fuel gas channel unit (76b) having exhaust fuel gas diverging holes (47) for diverging exhaust fuel gas used in reaction of anode (24) from fuel gas flow field and connected to supply passage through exhaust gas diverging passage (39).    USE - Used for e.g. vehicle.    ADVANTAGE - The fuel cell has a simple and compact structure, improved fuel gas utilization ratio, and desired power generation reaction. The amount of water supplied from the outside is reduced and the load of water supply pump is also reduced. The power generation efficiency is improved.    DETAILED DESCRIPTION - The fuel gas channel is connected to the fuel gas supply passage between the fuel gas flow field and an oxygen containing gas flow field (49). Each electrolyte electrode assembly includes the anode, a cathode (22), and an electrolyte (20) interposed between the anode and the cathode. The oxygen containing gas flow field is formed on the surface of the separator to supply oxygen containing gas to the cathode. The fuel gas flow field is formed on the other surface of the separator to supply fuel gas to the anode. The fuel gas supply passage extending through the fuel in stacking direction supplies fuel gas before consumption.
