Abstract: The present application provides combined cycle fuel cell systems that include a fuel cell, such as a solid-oxide fuel cell (SOFC), comprising an anode that generates a tail gas and a cathode that generates cathode exhaust. The system or plant may include adding fuel, such as processed or refined tail gas, to the inlet air stream of a reformer to heat the reformer. The system or plant may include removing water from the tail gas and recycling the removed water into an inlet fuel stream. The inlet air stream may be the cathode exhaust stream of the fuel cell, and the inlet fuel stream may be input hydrocarbon fuel that is directed to the reformer to produce hydrogen-rich reformate. The system or plant may direct some of the processed or refined tail gas to a bottoming cycle.
