Abstract:
1. A fuel cell power supply device comprising: a fuel cell; reactive gas supply means for supplying reactive gases to the fuel cell; supplied-amount regulating means for regulating an amount of reactive gases supplied from said reactive gas supply means to said fuel cell; target-amount-of-generated-electric-energy determining means for determining a target amount of electric energy generated by said fuel cell depending on a requested electric energy of a load which is connected to said fuel cell; gas supply control means for performing a gas supply control process to enable said supplied-amount regulating means to regulate the amount of reactive gases supplied from said reactive gas supply means to said fuel cell in order to supply an amount of reactive gases greater than the amount of reactive gases depending on said target amount of electric energy; and actual-amount-of-electric-energy detecting means for detecting an actual amount of electric energy generated by said fuel cell; said gas supply control means comprising means for comparing said target amount of electric energy and said actual amount of electric energy with each other, and performing said gas supply control process using said actual amount of electric energy as said target amount of electric energy if actual amount of electric energy is greater than said target amount of electric energy.
