Abstract:
1. A fuel cell vehicle, comprising: a propulsion motor capable of driving the vehicle; a fuel cell supplied with a reactant gas to generate power from an electrochemical reaction; a capacitor charged with generated power of said fuel cell and regenerative electric power of said propulsion motor, a reactant gas supply device which supplies said reactant gas to said fuel cell; a control apparatus which drives said reactant gas supply device with current supplied from said capacitor to start power generation of said fuel cell, said control apparatus estimating an output voltage of said fuel cell, said voltage being reduced when a current is supplied to said propulsion motor from said fuel cell; a capacitor charging device which charges said capacitor with current generated by said fuel cell when a terminal voltage has dropped due to supply of current to said reactant gas supply device by said control apparatus; a terminal capacitor voltage detecting device which detects the terminal voltage of said capacitor; and a propulsion motor drive permitting device which permits power supply from said fuel cell to said propulsion motor when said capacitor terminal voltage is equal to or greater than an estimated output voltage estimated by said control apparatus.
