<P>PROBLEM TO BE SOLVED: To start a fuel cell system without degradation of a secondary cell at starting of the fuel cell. <P>SOLUTION: The fuel cell system starts a fuel cell by setting the voltage supplied from a voltage converter at an open-circuit voltage of the fuel cell, and raising the voltage of the fuel cell from a starting voltage to the open-circuit voltage when the secondary cell is overcharged. When the secondary cell is not overcharged, the system starts the fuel cell by setting the voltage supplied from the voltage converter at a high-potential-avoiding voltage that is lower than the open-circuit voltage of the fuel cell after the elapse of a predetermined time following a command to open an FC relay, and raising the voltage of the fuel cell from the starting voltage to the high-potential-avoiding voltage. <P>COPYRIGHT: (C)2011,JPO&INPIT |
