Abstract
A power control system for controlling the supply of a reactant gas, such as air, for reaction within a fuel cell stack used to power, for example, a motor vehicle is set forth. The disclosed system may be used to reduce or eliminate compressor revving and instabilities common to prior systems in which fuel cell power output is dependent upon a flow of a reactant gas through a fuel cell stack, the flow of reactant gas being determined by the compressor speed.
