1. A method for reducing the weight of an air compression system for a fuel cell system, the method comprising the steps of:
providing a main air compressor for said air compression system, said main air compressor having a maximum air flow output, said maximum air flow output approximately equal to a continuous air flow requirement of said fuel cell system, said continuous air flow requirement occurring when said fuel cell system is operating in a continuous power mode, said main air compressor weighing less than an air compressor having a maximum air flow output approximately equal to a peak air flow requirement of said fuel cell system, said peak air flow requirement occurring when said fuel cell system is operating in a peak power mode such that said weight of said air compression system is reduced; and
providing a supplemental oxygen supply system which is fluidically coupled with said fuel cell system, said supplemental oxygen supply system providing supplemental oxygen to said fuel cell system when said fuel cell system has an air flow requirement which exceeds said continuous air flow requirement of said fuel cell system.
