<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which reutilizes an oxidizer off-gas, while reducing a load applied on a pressure control valve. <P>SOLUTION: A vortex tube 24 is installed in an exhaust passage 12c of an oxidizer off-gas, and the oxidizer off-gas that is flowing out of a cooled-air outlet 24a, is used for cooling the intake air of a compressor 21 and cooling a fuel cell 10. Furthermore, the oxidizer off-gas that is flowing out of a hot-air outlet 24b is used for heating the fuel cell 10 and a humidifying module 19. Thus, the oxidizer off-gas can be reutilized for cooling and for heating equipment that constitutes the system. Furthermore, the vortex tube 24 functions as a pressure loss unit and can reduce the load applied on the pressure control valve 23. <P>COPYRIGHT: (C)2008,JPO&INPIT |
