<P>PROBLEM TO BE SOLVED: To provide a reduced cost fuel cell/normal pressure turbine/hybrid system using a light-weight and easy-to-work structural material and a piping material which can effectively utilize the heat energy of fuel cell exhaust gas from a normal pressure/high temperature type fuel cell and which does not need an additional protective device in emergency. <P>SOLUTION: The fuel cell/normal pressure turbine/hybrid system is equipped with a burner 2 which causes the fuel cell exhaust gas G1 exhausted from the normal pressure/high temperature type fuel cell 1 to be burnt, a turbine 3 which causes an approximately normal pressure combustion gas G2 exhausted from the burner 2 to expand to negative pressure, a compressor 4 which raises the pressure of exhausted gas G3 from the turbine 3, and a heat exchanger 5 which carries out heat exchange between the high-temperature exhausted gas G3 from the turbine 3 and low-temperature air A supplied to the fuel cell 1. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
