ABSTRACT:
A fuel cell system including a fuel cell, an air compressor for supplying compressed air to the fuel cell, an expander for recovering energy from the air discharged from the fuel cell, and a heat exchanger for exchanging heat between the air discharged from the compressor and the air discharged from the fuel cell. The air discharged from the fuel cell is supplied to the expander after flowing through the heat exchanger.
