<P>PROBLEM TO BE SOLVED: To avoid beforehand problems of the increase of the power consumption of a battery caused by the decrease of a power generation amount of a fuel cell, and deteriorations of the battery and a battery electric path opening/closing switch or the like by effectively preventing that a request of excessive power is instantaneously sent to the battery, when the power generation amount of the fuel cell is decreased. <P>SOLUTION: When the decrease of the power generation amount of the fuel cell 1 is detected, a battery discharge current value supplied from the battery 21 when covering all the amount of the deterioration of the power generation of the fuel cell 1 with power from the battery 21 is estimated, an allowable current value allowable by the battery 21 and a battery main relay 27 is estimated, and when the battery discharge current value exceeds the battery allowable current value, the battery main relay 27 is switched to an off-state, thus disconnecting a battery load electric path. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
