Abstract
Back pressure is applied to a liquid fuel stored in a fuel storage unit by a pressure application unit, and a liquid fuel vaporization membrane that vaporizes the liquid fuel to thereby supply the vaporized fuel gas to an anode is formed by a nonporous membrane. Backed by this, the liquid fuel can be prevented from leaking out to the anode, so that the concentration of the liquid fuel can be increased to an optimum level.
