Abstract:
1. A control apparatus for a fuel cell vehicle comprising: a propulsion motor capable of driving a vehicle; a fuel cell, composed of a plurality of fuel cell units formed by sandwiching an electrolyte membrane between a fuel electrode and an oxygen electrode, which generates electric power by supplying a reactant gas to give an electrochemical reaction; a capacitor which is charged by a generated output of said fuel cell and regenerated electric power of said propulsion motor; a reactant gas supply device which supplies said reactant gases to said fuel cell; an output control device which receives an output current extracted from said fuel cell and controls said output current of said fuel cell; a regenerative electric power calculating device which calculates the regenerative electric power which can be generated by regenerative operation of said propulsion motor; and a chargeable power calculating device which calculates the chargeable power which can be charged to said capacitor, wherein when said chargeable power is less than said regenerative electric power, said output control device restricts the value of the output current from said fuel cell to zero, and when said chargeable power is greater than said regenerative electric power, said output control device cancels the restriction on the output current of said fuel cell.
