ABSTRACT:
The invention relates to a method for operating a fuel cell system consisting of a fuel cell, a reformer for generating a hydrogen-rich gas, and a combustion chamber in which the fuel cell exhaust gases are oxidized to generate the heat energy required in the reformer. According to the invention, in those operating states in which the heat energy supplied to the reformer from the combustion chamber is insufficient, additional amounts of fuel and oxygen are supplied to the reformer, so that additional heat energy is produced directly in the reformer by the oxidation of the fuel. At the same time, during the oxidation of the fuel in the reformer, steam is produced that can be used in steam reformation. Advantageously, adjustment of the additional amount of fuel and the oxygen supplied is performed as a function of the reformer temperature.
