ABSTRACT:
According to one embodiment, a direct-methanol fuel cell includes an anode into which an aqueous methanol solution is introduced as fuel, a cathode into which an oxidizing agent is introduced, an electrolyte membrane interposed between the anode and the cathode, an anode separator which is disposed on the anode side and includes a fuel passage formed on a surface facing the anode, and a cathode separator which is disposed in the cathode side and includes an oxidizing gas passage formed on a surface facing the cathode. At least the cathode separator is provided with a coating film including a macromolecular polymer having a water-repellent functional group and an ionic functional group, the coating film being formed on at least an inside surface of the oxidizing gas passage.
