Abstract
An apparatus for supplying a fuel gas comprises a reformer for steam reforming of methanol supplied from a methanol tank, and a methanol-removing means for removing unreacted methanol contained in the fuel gas delivered from the reformer. The fuel gas, from which the unreacted methanol is effectively removed, can be supplied to a fuel cell assembly. Accordingly, no unreacted methanol remains in the fuel gas to be supplied to an anode of the fuel cell. Thus the power generation performance can be effectively maintained.
Claims10
A method for supplying a fuel gas to a fuel cell assembly comprising a plurality of stacked fuel cells, each of said fuel cells including an anode and a cathode opposed to each other with a solid polymer electrolyte membrane interposed therebetween, said method comprising the steps of:
- producing said fuel gas for operating said fuel cell assembly from methanol by the aid of a fuel-producing means;
- removing unreacted methanol contained in said produced fuel gas;
- and
- supplying, to said fuel cells, said fuel gas from which said unreacted methanol has been removed.
A method for supplying a fuel gas to a fuel cell assembly from a fuel gas producing means that uses methanol as a supply gas source, the method comprising the step of:
- removing unreacted methanol contained in said fuel gas produced by said fuel gas producing means.
