Abstract:
1. System comprising an internal combustion engine which has a heat transfer circuit, a fuel cell, and a climate control unit which is accommodated in the heat transfer circuit of the internal combustion engine, wherein a heat transfer means is provided for transferring exhaust heat of the fuel cell to the heat transfer circuit and a bridging means is provided for bridging a segment of the heat transfer circuit which runs through the internal combustion engine so that in a bridged operating state, an isolated circuit is formed; and wherein the heat transfer circuit is configured depending on the operating situation such that, when driving, said bridging means is inactive and exhaust heat of the fuel cell is transferred to the internal combustion engine and in stationary operation said bridging means is inactive and the exhaust heat of the fuel cell is available only to said isolated circuit for use by the climate control unit for heating of the motor vehicle interior.
