To effectively utilize waste heat of an on-vehicle device and suppress increase in the number of components on a system.SOLUTION: A heating system 10 of a fuel cell vehicle includes an electric heater 20, a temperature rising pipeline 12, heater cores 30, 32A and 32B, and a heat dissipation pipeline 14. The temperature rising pipeline 12 supplies a refrigerant to the electric heater 20 and a fuel cell stack 15 provided on the upstream of the electric heater 20. The heat dissipation pipeline 14 is connected to the downstream of the temperature rising pipeline 12 and supplies a refrigerant to the heater cores 30, 32A and 32B, and the downstream end thereof is connected to the temperature rising pipeline 12. The electric heater 20 includes a braking resistor 22 and a switch 24. The braking resistor 22 is electrically connected to a rotary electric machine 60 as a driving source. The switch 24 can switch energization and breakage between the braking resistor 22 and a power source (fuel cell stack 15).SELECTED DRAWING: Figure 1

    【課題】車載機器の排熱を有効利用可能であるとともに、システム上の部品点数の増大を抑制可能とする。【解決手段】燃料電池車両の暖房システム10は、電気ヒータ20、昇温配管12、ヒータコア30,32A,32B、及び放熱配管14を備える。昇温配管12は、電気ヒータ20及び当該電気ヒータ20の上流に設けられた燃料電池スタック15に冷媒を供給する。放熱配管14は、昇温配管12の下流に接続されヒータコア30,32A,32Bに冷媒を供給し下流端が昇温配管12に接続される。電気ヒータ20は、制動抵抗器22及びスイッチ24を備える。制動抵抗器22は、駆動源である回転電機60に電気的に接続される。スイッチ24は、制動抵抗器22と電源(燃料電池スタック15)との通電及び切断を切替可能となっている。【選択図】図1
