POWER GENERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a power generation unit using a solid oxide fuel cell securing necessary heat by burning fuel gas having passed through a fuel cell, and preventing overheat of a preliminary reformer.

SOLUTION: The power generation device is equipped with: the preliminary reformer 110 decomposing hydrocarbon whose number of carbon is 2 or more contained in fuel to hydrocarbon whose number of carbon is 1 or less; a main reformer 18 decomposing hydrocarbon contained in the preliminarily reformed fuel; a solid oxide fuel cell generating electric power by the reaction of the reformed fuel gas and air; a means burning fuel gas passed through the fuel cell; a means cooling combustion gas by heating a heating object with high temperature combustion gas generated in the burning means; and a means hating the preliminary reformer 110 with the combustion gas cooled with the cooling means.
