    摘要: A method for activating a direct oxidation fuel cell including an anode, a cathode, and a proton-conductive electrolyte membrane interposed between the anode and the cathode is provided. The anode and the cathode each have a catalyst layer on a face in contact with the proton-conductive electrolyte membrane. This method activates the fuel cell by passing a current through the fuel cell from an external power source, with the positive electrode and the negative electrode of the external power source connected to the anode and the cathode of the fuel cell, respectively, while supplying an organic fuel and an inert gas to the anode and the cathode, respectively.

    摘要: A method for operating a fuel cell system including a fuel cell stack composed of a plurality of cells connected in series. The method includes the steps of: (a) supplying a fuel and an oxidant to anodes and cathodes of the cells, respectively, depending on a load to generate power at a constant voltage under constant voltage control; (b) temporarily suspending the supply of the oxidant with the fuel being supplied; and (c) lowering the constant voltage to a predetermined voltage simultaneously with or immediately before the suspension of the supply of the oxidant. According to this operation method, when the supply of the oxidant is suspended, a platinum catalyst in the cathodes can be reduced and reactivated in all the cells.

    摘要: A method for operating a direct methanol fuel cell is provided. The fuel cell includes a fuel cell main body having a fuel electrode and an air electrode disposed in opposing positions on either side of an electrolyte film. In this method, an aqueous methanol solution is supplied directly to the fuel electrode. A quantity of the aqueous methanol solution supplied is controlled in accordance with an electric current value drawn from the fuel cell main body so as to minimize a quantity of unused methanol within a discharge fluid discharged from the fuel electrode.
