MOTOR VEHICLE COMPRISING AN INTERNAL COMBUSTION ENGINE AND AN AUXILIARY POWER UNIT

摘要

The invention relates to a motor vehicle comprising an internal combustion engine (12) and an auxiliary power unit containing a fuel cell (50). A cooling and heating circuit (10) permits energy fluxes and/or material fluxes of the internal combustion engine (12) and the fuel cell (50) to be coupled together. According to the invention, the cooling and heating circuit (10) comprises a first sub-circuit (26) and a second sub-circuit (44), the first (26) of which is allocated to the internal combustion engine (12) and the second (44) of which is allocated to the fuel cell (50) and the two sub-circuits (26, 44) are interconnected by a flow line (62) comprising a flow valve (66) and a return line (64) comprising a return valve (68).
