An energy generation system and method are presented for use in operating a heat engine. The energy generation method comprises: reducing a CO2 gas into CO and O2 gases; reacting said CO and O2 gases, thus combusting the CO gas, and yielding a substantially pure CO2 outlet gas; and supplying said CO2 outlet gas to the heat engine as a working gas in its heat-to-work generation process.

PROBLEM TO BE SOLVED: To provide a gas heating device capable of shortening warm-up time for a fuel cell without using a heater such as an electric heater. SOLUTION: The gas heater includes an oxidation reactor for increasing temperature of mixed gas of hydrogen and air (or oxygen) by oxidation heat of hydrogen in the presence of a hydrogen oxidation catalyst. The hydrogen oxidation catalyst is constituted by supporting catalytically active metal on top of a carrier comprising oxidation reducible metallic oxide. COPYRIGHT: (C)2011,JPO&INPIT
