HEAT RECOVERY APPARATUS BASED ON FUEL CELL AND OPERATING METHOD THEREOF

摘要

Provided are a heat recovery apparatus based on a fuel cell and an operating method thereof. In the fuel cell-based heat recovery apparatus and the operating method thereof, hot water and steam may be generated by using heat generated while a molten carbonate fuel cell (MCFC) operates to supply the generated hot water or steam to buildings, thereby reducing a rate of operation in cooling/heating equipment using electricity so as to reduce air-conditioning costs.

主权项

1. A fuel cell-based heat recovery apparatus comprising:
a first switching unit introducing heat generated by a molten carbonate fuel cell (MCFC) into a heat exchanger or blocking the introduction of the heat into the heat exchanger; a second switching unit discharging the heat through a discharge hole or blocking the discharge of heat through the discharge hole; a third switching unit introducing a fluid stored in a condensed tank into a fluid circulating unit or blocking the introduction of the fluid into the fluid circulating unit; the fluid circulating unit circulating the fluid introduced by the third switching unit; a state sensing unit measuring a temperature of the heat generated by the MCFC, a flow rate within a tube through which the fluid passes, and a temperature and water level within the condensed tank; and a control unit controlling each of the units according to an operating or stopping algorithm.
