NOVELTY - The system has a fuel cell (60) e.g. proton exchange membrane (PEM) fuel cell, for generating electric and thermal energy. An energy storage device receives a portion of the electric energy. A heat exchanger e.g. generator (72), transfers a portion of the thermal energy to a refrigeration system (25) to heat the refrigerant. A heating device is thermally coupled with the refrigeration system. A control system cycles the fuel cell and the heating device to drive a refrigeration cycle of the refrigeration system alternatively with the fuel cell and the heating device.    USE - Integrated energy management system for managing thermal and electrical energy generated in a fuel cell-coupled refrigeration system installed in a building and an electric vehicle. Can also be used for a dishwasher, a clothes washer, a dryer, a refrigerator and a freezer.    ADVANTAGE - The system controls the operation of the refrigeration system to allow for further efficiency in a heating and cooling operation, thus reducing the total energy cost to the consumer. The system operates to recharge or condition any additional electrical energy storage devices and reduce compressor load in vapor compression cycles such that the system attains longer lifetimes. The fuel cell provides heat generated from the power producing electrochemical reaction to promote cooling, thus providing temperature regulation for high cost electrical components such as batteries, control systems or power electronic devices. The output power of the fuel cell is inherently direct current (DC), so that the fuel cell can power DC or brushless DC electric motors that power the compressor used in a vapor compression refrigeration cycle, thus increasing the efficiency of the refrigeration system and enhancing the service life of the refrigeration system.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for operating an integrated energy management system.    DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of a fuel cell-coupled refrigeration system including a fuel cell, a heat driven refrigeration system, and a heat exchanger for use with an integrated energy management system.
