Fuel cell for motor vehicle has heat exchange circuits between fuel cell and ambient air and interior of passenger compartment

摘要

The fuel cell (1) circuit for a motor vehicle is positioned in a primary circuit (17a,b;18a,b;20a,b;25) for cooling and humidification, containing dematerialized water. The primary circuit is in heat exchange relation (21) with a secondary circuit containing a refrigerant fluid to increase the heat of the first fluid. The secondary circuit (26) has a second heat exchanger (34) in contact with ambient air. A third heat exchanger can be connected to the second circuit and is in contact with the vehicle passenger space.
