The disclosure relates to a fuel cell device arrangement for producing electrical energy, having at least one fuel cell anode and cathode, an electrolyte for conveying ions between the anode and the cathode, and a passage separate from the electrolyte for the electrons travelling from the anode to the cathode. A control arrangement can prevent the formation of carbon by calculating a thermodynamic equilibrium model based on thermodynamic equilibriums of chemical reactions for the feedback recirculation of fuel. Measurement values are obtained, at least from the electric current and the fuel flow rate, for calculating the fuel composition. Conversion values set on the basis of the thermodynamic equilibrium model for the fuel are calculated using the measurement values and fuel composition. The calculation can be repeated to produce the conversion values by which the fuel composition can be determined to converge with sufficient accuracy, so that operation of the fuel cell device can remain within safety limits according to the thermodynamic equilibrium model. |
