PURPOSE:To reduce power consumption of a compressor and to improve the system efficiency, by providing a system having oxygen-rich film at the prestage of compressor provided in an air-feed system path to a fuel cell thereby supplying air having high oxygen concentration to the compressor. CONSTITUTION:Fuel 7 is fed through a hydrogen generator 8 into the fuel chamber 6 in a fuel cell 1 while air is fed from a compressor 11 through an air supply system path 9 into an air chamber 5 to produce power. An oxygen rich means 12 where an oxygen-rich film 15 is stretched in the way of an air path 14 is arranged at the prestage of the compressor 11 to pass the air (C) forcefully through said film 15 by sucking force of compressor 11 while to separate the blocked nitrogen component (D) and discharge to the outside thus to feed the oxygen-rich air to the compressor 11. Since unnecessary nitrogen is not required to be compressed, the power of compressor can be reduced resulting in improvement of system efficiency. |
