Thermal management of a fuel-cell-powered electric vehicle having at least one high temperature heat transfer circuit and one low temperature heat transfer circuit each using the same dielectric heat transfer medium as the other. The circuits are in flow communication with each other so that hot heat transfer medium can flow from the high temperature circuit into the low temperature circuit, and cooler heat transfer medium can flow from the low temperature circuit into the high temperature circuit under controlled conditions for heating the fuel cell when it is cold, cooling a fuel processor when it is hot, and otherwise meeting the thermal demands of the vehicle.
