摘要： A direct oxidation fuel cell includes at least one unit cell. The at least one unit cell includes: an anode; a cathode; a hydrogen-ion conductive polymer electrolyte membrane interposed between the anode and the cathode; an anode-side separator having a flow channel for supplying and discharging a fuel to and from the anode; and a cathode-side separator having a gas flow channel for supplying and discharging an oxidant gas to and from the cathode. A water-repellent layer is formed on each side of the electrolyte membrane so as to surround the anode or the cathode. When the MEA is hydrated or when a liquid fuel is supplied to the cell for power generation, the part of the electrolyte membrane surrounding the electrodes is prevented from becoming swollen or deformed rapidly. It is therefore possible to ensure adhesion of the electrodes to the electrolyte membrane.
