FUEL CELL POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To reduce the highest pressure in a reform gas system of a fuel cell power generation system.

SOLUTION: This fuel cell power generation system has: a reformer 1 for reacting a hydrocarbon-based fuel with steam to reform it into hydrogen; a CO shift unit 3 for reducing CO in a reform gas produced in the reformer 1; a CO selection oxidation unit 5 for selectively oxidizing CO remaining in the reform gas discharged from the shift unit 3; and a fuel cell 7 for generating power by reacting the reform gas discharged from the oxidation unit 5 with oxygen. The fuel cell power generation system is characterized by that an ejector 11 using steam for a driving fluid is installed at least one position of a gas line from the reformer 1 to an anode exhaust gas line 15 of the fuel cell 7; and the steam is supplied from a steam generator 25 installed in a combustor 9 for burning an anode exhaust gas.
