1. An aircraft fuel cell system comprising:
a plurality of electronically controlled air compressors operably coupled to a fuel cell and configured to provide compressed air to said fuel cell for operation thereof, said fuel cell configured to be coupled to an aircraft; and
an air compressor control system configured to control flow of compressed air from said plurality of electronically controlled air compressors to said fuel cell independently of power load requirements of said aircraft, wherein said plurality of electronically controlled air compressors are arranged in parallel to meet a compressed air flow rate demand of said fuel cell of said aircraft fuel cell system, said air compressor control system to enable delivery of on demand power to said aircraft, said delivery of said on demand power reducing power output requirements of a buffer battery such that said aircraft fuel cell system is able to operate with reduced said power output requirements for said buffer battery or without requiring said buffer battery.
