NOVELTY - Fuel cell apparatus (10) comprises: fuel cell generating electric power including electrolyte membrane (12a), fuel electrode (12b) including anode catalyst which is disposed in one side of electrolyte membrane that is supplied with liquid fuel, and discharges gas generated by a chemical reaction accelerated by the anode catalyst, and an oxidizing agent electrode (12c) which includes a cathode catalyst; and a control unit controlling load applied to fuel cell and stopping increase of load after elapsing predetermined time.    USE - The apparatus is useful as auxiliary electric power source, various kinds of primary cells, physical cell (solar cell or thermal cell), and/or condensers with high capacitance.    ADVANTAGE - The apparatus: recovers from the output lowering with time in spite of the fact that an air forcibly-supplying unit such as an electric pump for supplying air forcibly through the air supply path to the oxidizing agent electrode of the fuel cell is not used; and creates the state in which oxygen is insufficient in the oxidizing agent electrode more easily and efficiently. The increase of electric power used in the auxiliary units or machinery of the fuel cell apparatus can be reduced as much as possible.    DETAILED DESCRIPTION - Fuel cell apparatus (10) comprises: a fuel cell generating electric power including an electrolyte membrane (12a), a fuel electrode (12b) including an anode catalyst which is disposed in one side of the electrolyte membrane that is supplied with liquid fuel, and discharges gas generated by a chemical reaction accelerated by the anode catalyst, and an oxidizing agent electrode (12c) which includes a cathode catalyst, which is disposed in the other side of the electrolyte membrane and supplied with air; and a control unit controlling a load applied to the fuel cell, where the control unit increases the load in at least one of two cases, one case being when electric power generated by the fuel cell lowers below a predetermined reference value and another case being at predetermined time intervals, and stopping the increase of the load after elapsing a predetermined time from the start of the increase of the load.
