<P>PROBLEM TO BE SOLVED: To provide a fuel cell power generation system which efficiently removes ammonia in fuel gas, thereby suppressing voltage reduction and degradation of electrolyte etc., and which is excellent in power generation efficiency and durability. <P>SOLUTION: A fuel cell power generation system comprises: a fuel cell having an anode and a cathode; a fuel gas supply unit which includes a modification unit for modifying material gas so as to generate fuel gas containing hydrogen, and supplies the fuel gas to the anode; an oxidant gas supply line for supplying oxidant gas containing oxygen to the anode; and a radical supply unit provided on the oxidant gas supply line, generating radical in the oxidant gas, and supplying the radical into the fuel gas. The radical can decompose ammonia contained in the fuel gas, thereby suppressing voltage reduction and degradation of electrolyte due to the ammonia, which can improve power generation efficiency and durability of the fuel cell power generation system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
