WIPO Patent Application WO/2011/036716
Kind Code:
A1
Abstract:
A fuel cell system comprises: a membrane electrode assembly including an anode catalyst layer, a cathode catalyst layer, and an electrolyte membrane inserted between the anode catalyst layer and the cathode catalyst layer; a generator unit in which a first layer and an anode channel are disposed on the anode catalyst layer side of the membrane electrode assembly, the first layer including a carbon material and having porous and water-repellent properties, the anode channel having a fuel supply portion for supplying a fuel to the anode catalyst layer through the first layer and a fuel discharging portion for discharging a discharged material from the anode catalyst layer through the first layer; and a control unit electrically connected to the generator unit and electrically connectable to a load. The operation of the control unit includes a step of stopping power feeding from the generator unit to the load and a step of preventing an oxidation agent from intruding into the generator unit from the outside.
