Abstract
A fuel cell system and related method are disclosed having a system controllerthat executes enthalpy calculation based on status signals, related to anode off-gas and cathode off-gas, detected by a temperature detector, a pressure detectorand a humidity detectorfor thereby predicting a combustion temperature of a combustorduring purging. In the presence of a predicted combustion temperature exceeding an upper limit, cathode off-gas is increased in volume to limit a combustion temperature of the combustorto a value below the upper limit value.
