摘要： A fuel cell system to be mounted on an electric vehicle such as a hybrid vehicle or an electric vehicle. Cooling water is supplied from a cooling water inlet of a stack manifold, flows through a fuel cell stack, and returns to the stack manifold. A groove is formed on the rear surface side of the stack manifold, constituting, together with a terminal, a cooling water channel. The cooling water flows through the cooling water channel, and is discharged to the outside from a cooling water outlet. The cooling water channel is formed extending from the rear side to the front side of the vehicle, and warms an end plate. A pipe length of the cooling water channel to a radiator mounted in a front part of the vehicle is reduced.

摘要： Flux concentration cores that encircle bus bars are arranged at different heights. When viewed from an extending direction (a Z-direction) of the bus bars, the first flux concentration core and the second flux concentration core that are adjacent to one another partially overlap each other, and the second flux concentration core and the third flux concentration core that are adjacent to each other partially overlap each other. Therefore, the flux concentration cores are able to be arranged around the bus bars even when the spaces between the bus bars are narrow.

摘要： A vehicle equipment mounting structure that arranges a motor case, in which a rotary electric machine that drives a vehicle is housed, in an engine compartment, and that includes a PCU that controls the rotary electric machine, and an auxiliary battery that supplies electric power to the PCU. This structure includes a fixing portion that fixes the PCU onto the motor case, and a connecting portion that connects the auxiliary battery to a side member that absorbs an impact load by being crushed in a crushing direction. The connecting portion has a displaceable member that is displaceable in the crushing direction. The auxiliary battery is arranged on a vehicle front side of the PCU such that the PCU and the auxiliary battery partially overlap in the crushing direction. The auxiliary battery is arranged so as to be able to move past the PCU in response to an impact load.
