Abstract:
A solid electrolyte fuel cell power generating system comprising:a) a solid electrolyte fuel cell containing an anode, an anode fuel inlet and an anode exhaust gas outlet, a fuel source in communication with the anode inlet, a cathode, a cathode oxidant inlet and a cathode exhaust oxidant outlet, an oxidant source in communication with the cathode oxidant inlet; andapparatus for recycling at least part of an anode exhaust gas stream emanating from the anode exhaust gas outlet to the anode inlet, said apparatus comprising a heat exchanger in communication with the anode exhaust gas outlet, a condenser in communication with said heat exchanger for condensing water vapor from said anode exhaust gas stream at a condensing temperature below the temperature of said anode exhaust gas stream at the anode exhaust gas outlet, a first combustor in communication with said heat exchanger and the anode inlet and a low temperature blower for controlling the recycle rate of flow of the anode exhaust gas stream into said first combustor and the flow rate of gas into the anode inlet.
