<P>PROBLEM TO BE SOLVED: To provide an activation process method and its device for a membrane/electrode assembly of a fuel cell. <P>SOLUTION: In an operation process for attaining activation of the fuel cell with a power generating part, a fuel treatment device, a blasting device, and a control device, the control device starts up the fuel treatment device and makes fuel liquid flow into an anode side of the power generating part to sustain for a T1 hour, the power generating part selects an on-operation of a specific load of an inner load feeding circuit to output power up to the specific load of the inner load feeding circuit in a power output formula around the maximum output power area in a relative curve of output voltage-output power and selects startup of the blasting device to sustain for a T2 hour, and then, to sustain an off-operation of the blasting device for a T3 hour, and decides on the number of repeated execution of these steps. Each of the above hours of T1, T2 and T3 is decided in accordance with selection of either formula of the membrane/electrode assembly characteristics of the power generating part or preferable parameters obtained in the experiment. <P>COPYRIGHT: (C)2008,JPO&INPIT |
