<P>PROBLEM TO BE SOLVED: To enable to safely supply electric power to a load. <P>SOLUTION: A voltage value of each cell is monitored in a state in which a load is not electrically connected to a cell stack directly, but a light load lighter than the load is connected (S16, S17), and in case a voltage value of each monitored cell is not lower than a prearranged voltage value, the cell stack is controlled so that the load is electrically connected to the cell stack (S18). <P>COPYRIGHT: (C)2007,JPO&INPIT |
