A thermal priority fuel cell power plant includes a cell stack assembly for generating an electrical power output. The cell stack assembly includes an anode, a cathode, and a waste heat recovery loop. The waste heat recovery loop is configured to remove waste heat generated from the electrochemical reaction and is thermally coupled to the cell stack assembly for managing the waste heat of the cell stack assembly and for supplying thermal power to a thermal load demand. The waste heat recovery loop includes a heat exchanger in heat exchange relationship with the coolant outlet conduit and the thermal load demand. A controller is operatively associated with the cell stack assembly and the waste heat recovery loop. The controller controls the operation of the cell stack assembly by adjusting a fuel cell power plant parameter responsive to the thermal load demand.

System and method for thermal priority operation of a fuel cell power plant

An on-site power plant () has a controller () that selectively controls operation of prime movers (). In one example, the controller () changes the number of operating prime movers responsive to a transient in a load () requirement while continuing to operate at least one of the prime movers. One example includes prioritizing the prime movers () for operation based upon the needs of a cogeneration unit () associated with the prime movers for providing a temperature control function within a facility. Another example includes controlling operation of the prime movers based upon a capacity for fueling the prime movers.
