A fuel cell system has a reformer, a water tank for supplying water to humidify a hydrogen gas and an oxidizing gas which has been reformed by the reformer, a fuel cell for being supplied with the humidified hydrogen gas, and first and second gas-liquid separators for separating substances discharged from the fuel cell into gases and water, and supplying the separated water to the water tank. The fuel cell system needs no water supply from an external source and can continuously supply the water from the water tank to the fuel cell.

[ What is claimed is:] [1.] A fuel cell system for use on a mobile body, comprising:a fuel cell stack comprising a plurality of fuel cells each having an ion exchange membrane, and an anode and a cathode which sandwich said ion exchange membrane therebetween;a water reservoir for storing water to humidify a fuel gas to be supplied to said fuel cell stack;gas-liquid separating means for separating substances discharged from said fuel cell stack into gases and water and supplying the separated water to said water reservoir; anda reformer for reforming a hydrocarbon with steam to generate a hydrogen gas as said fuel gas, wherein water is supplied to the reformer from said reservoir for producing said steam, said fuel cell stack having a fuel gas utilization ratio sufficient to cause an amount of the separated water discharged from said fuel cell stack to at least equal an amount of the water being supplied to said fuel cell stack and said reformer.
