SOFC Anode

Prior solutions require maintaining fuel flow while shutting down the air from first to the fuel cell during shutdown. This leads to a loss of fuel during shutdown of the fuel cell operation. During the shutdown, air flowing into the combustion chamber can flow into the anode of the fuel cell. A simple way of preventing this is to place chec...
