FUEL CELL

摘要

Disclosed is a fuel cell comprising a cathode catalyst layer (2), an anode catalyst layer (3), a proton conductive membrane (6) arranged between the cathode catalyst layer (2) and the anode catalyst layer (3), and a fuel vaporization layer (10) for supplying the vaporized component of a liquid fuel to the anode catalyst layer (3). In this fuel cell, water generated at the cathode catalyst layer (2) is supplied to the anode catalyst layer (3) through the proton conductive membrane (6), and an aqueous methanol solution having a concentration of more than 50 mol% or liquid methanol is used as the liquid fuel.
