Abstract
This invention pertains to methods for controlling thermal aspects during operation of a solid oxide fuel cell (SOFC) system, including controlling target cathode and anode inlet stream temperatures and differential temperatures defined by the anode and cathode inlet and outlet streams. In one aspect, thermal management is achieved by controlling a combustion stream temperature and by employing one heat exchanger having two cold side pathways. In another aspect, thermal management is achieved by controlling a temperature of a combustion stream distributed through a cathode feed heat exchanger and an anode feed heat exchanger, optionally with bypassing a portion of the cathode air stream around the cathode feed heat exchanger. In another aspect, thermal management is achieved by employing a cathode feed heat exchanger to heat a cathode air stream and by employing an equalizer heat exchanger to equilibrate temperatures of the resulting heated cathode air stream and an anode fuel stream.
