초록

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...
