  • Patent number: 11040629
    Abstract: A fuel cell vehicle according to the present disclosure includes, in a front room: a fuel cell stack fixed to an upper part of a stack frame; a high voltage element fixed to an upper part of the fuel cell stack; and an ion exchanger that is arranged in front of the fuel cell stack and the high voltage element. The stack frame is provided with an inclined part, and when the ion exchanger is displaced rearward at the time of a frontal crash of the fuel cell vehicle, a rear part in a lower end of the ion exchanger is slid along an inclined surface of the inclined part and the ion exchanger is displaced in a diagonally upward direction, whereby the cap part of the ion exchanger is positioned on the upper side in the vertical direction with respect to the high voltage element.
    Type: Grant

  • Patent number: 10355291
    Abstract: The fuel cell system is provided with a radiator, a first flow passage in which refrigerant flows from a fuel cell stack towards a radiator, a second flow passage in which refrigerant flows from the radiator towards a fuel cell stack, a bypass flow passage that connects the radiator with a position in the second flow passage at which refrigerant flows into the fuel cell stack, and a control part. In the bypass flow passage, an on-off valve and a reserve tank are provided from the upstream side. The control part feeds refrigerant to the fuel cell stack by opening the on-off valve and allowing refrigerant previously stored in the reserve tank to join the second flow passage in a case where refrigerant temperature detected by an inflowing refrigerant temperature detection part exceeds previously set base temperature.
