Fuel cell system that provides high grade heat to an absorption chiller

摘要

A standard phosphoric acid fuel cell power plant has its heat exchanger removed such that a higher temperature coolant flow can be directed from the system to the generator of an absorption chiller to obtain improved efficiency in the chiller. In one embodiment, the higher temperature coolant may flow directly from the fuel cell stack to the generator and then back to the high temperature coolant loop. Either a double effect absorption chiller or a single effect absorption chiller may be used.
