Abstract:
1. A method of load following operation of a fuel cell system comprising a reformer having a reforming catalyst layer, for reforming a hydrocarbon-based fuel to produce a reformed gas containing hydrogen, and a high temperature fuel cell for generating electric power using the reformed gas, the method comprises determining before start of the load following operation functions F=f(P) and P=f a minimum value of flow rate of the hydrocarbon-based fuel represented as F a plurality of temperatures T the load following method comprising: A) measuring a temperature T of the reforming catalyst layer; B) adopting one of the flow rates from the plurality of flow rates G C) when the reformable flow rate F D) when the reformable flow rate F performing step d1 if a fuel cell output demand value P d1) calculating a flow rate f(P if f(P if f(P d2) calculating a flow rate f(P if f(P if f(P wherein the output demand value P
