A fuel gas supply device is equipped with a reformer for conducting steam reforming of methanol which is supplied from a methanol tank, and a hydrogen gas supply means for supplying hydrogen gas only, which is contained in the fuel gas derived from the reformer, to a fuel cell. By passing the fuel gas through a hydrogen permeable membrane or a pressure-swing adsorption device, a fuel gas in which any unreacted methanol is reliably removed therefrom can be supplied to the fuel cell. According to further embodiments, unreacted methanol is caused to positiv...
[ I claim:] [1.] A fuel gas supply method for supplying fuel gas to a fuel cell, comprising the steps of:generating a fuel gas from methanol in a fuel gas generating device;forcibly reacting and removing unreacted methanol contained in the generated fuel gas on a fuel electrode side of a fuel cell stack; andsupplying said fuel gas from which unreacted methanol has been removed to said fuel cell stack.
