Abstract
A method of operating a fuel cell system includes providing fuel and air to a stack of fuel cells located in a hotbox, operating the stack to generate an anode exhaust and a cathode exhaust, in a startup mode, providing a first amount of the anode exhaust and the cathode exhaust to an anode tail gas oxidizer (ATO) located in the hotbox to oxidize the anode exhaust and to generate heat which is provided to the stack, and in a steady-state mode, stopping providing the anode exhaust to the ATO or providing to the ATO a second amount of the anode exhaust which is smaller than the first amount, and providing the anode exhaust and the cathode exhaust outside the hotbox.
