<P>PROBLEM TO BE SOLVED: To purify exhaust gas exhausted from an internal combustion engine and including nitrogen oxides without bringing reduction of energy efficiency and enlargement of a system in a system equipped with the internal combustion engine as a power source. <P>SOLUTION: The exhaust gas exhausted from the engine 10 and including the nitrogen oxides is supplied to a cathode of a fuel cell 20, hydrogen-rich gas generated by a hydrogen gas generating device 30 is supplied to an anode of the fuel cell 20, and electric power is generated by electrochemical reaction of hydrogen with the nitride oxides, and the nitride oxides are decomposed. A hydrogen separation type fuel cell operated at a temperature almost equivalent to a temperature of the exhaust gas exhausted from the engine 10 is applied to the fuel cell 20. <P>COPYRIGHT: (C)2008,JPO&INPIT |
