Equipment for heat recovery on fuel cell vehicle, comprises principal cooling circuit with electronically controlled supplementary heat exchanger to produce hot water or to heat the vehicle cabin

摘要

A fuel cell (1) has a principal cooling circuit (2) with a pump (3) and heat exchanger (4) which heats the cabin by air flow (5). A supplementary exchanger (12) may supply excess heat to a secondary circuit (13) hot water reservoir (15) as directed by an electronic control unit (17). The control unit has a manual input (22) and is connected to a pump (14) and fuel cell and secondary circuit temperature sensors (19,21) An Independent claim is also included for: The method of heat recovery from a vehicle fuel cell using a supplementary heat exchanger and hot water reservoir
