PURPOSE: To improve efficiency in a whole power plant by methane-gassing a carbon oxide rich gas in a supply gas by a methane-gassing unit, utilizing a fuel cell discharged heat on a regeneration catalysis floor, and regenerating it as an anode process gas. CONSTITUTION: Hydrogen and a carbon oxide rich gas from respective lines 4 and 6 and water steam are supply gases, a carbon oxide rich gas is methane- gassed by a methane-gassing unit 9, heat absorption reaction for absorbing discharge heat of a solid oxide fuel cell 2 to be formed by an anode chamber 2a, a cathode chamber 2c, and an electrolytic matrix 2e is generated on a regeneration catalysis floor 13, regenerated into an anode process gas, and supplied to the chamber 2a via a line 14. Therefore, a heat required for heat absorption regeneration process is supplied by heat discharge, and at the same time the battery 2 is cooled, piping of a cathode gas supply loop is reduced and simplified, and efficiency of the whole fuel power plant is enhanced. |
