PROBLEM TO BE SOLVED: To provide a load follow-up operation method for a fuel cell system, surely allowing reforming, capable of preventing a flow channel from being clogged, and capable of preventing an anode from being deteriorated.SOLUTION: This load follow-up operation method for the fuel cell system finds preliminarily functions F=f(P) and P=f(F) of an electric output P and a fuel flow rate F required to output the electric output P, sets a reforming catalyst layer temperature Tand a fuel flow rate Greformable at the reforming catalyst temperature T, stops electric power generation, when F<F(minimum value of F) where Fdenotes Gcorresponding to the maximum Tat a catalyst layer measured temperature T or less, carries out (1) when an output required value P≤the maximum output Pin case of F≥F, and carries out (2) when P>P, where (1): the output is brought into Pand the fuel fow rate is brought into f(P), when f(P)≤F, and the output is brought into the maximum value less than Pof P calculated by P=f(F) and the fuel fow rate is brought into F, when f(P)>F, and where (2): the output is brought into Pand the fuel fow rate is brought into f(P), when f(P)≤F, and the output is brought into the maximum value of P calculated by P=f(F) and the fuel flow rate is brought into F, when f(P)>F. |
