A method is disclosed for producing electricity in high temperature fuel cell systems. Gas is circulated at anode sides of the fuel cells. A gas composition at anode sides is determined for providing composition information, and desired temperature conditions are arranged for producing electricity with fuel cells. Rated power of the fuel cell system is controlled by an auxiliary water feed to the fuel cell system by utilizing the composition information, by performing controlled gas recirculation at anode sides by utilizing the composition information by changing the gas recirculation, when a desire arises, and by performing controlled gas feed in to the fuel cell system by utilizing the composition information by changing the gas feed, when a need arises, to change the rated power of the fuel cell system to keep electricity production conditions substantially optimal for the gas used as fuel in the high temperature fuel cell system. |
