摘要： A fuel cell unit (10) includes a fuel cell stack (20) having a coolant channel (23) inside where coolant flows in one direction, and having a first surface (27) parallel to a direction in which the coolant channel extends; a boost converter (40) disposed across a gap from the first surface (27) without being partitioned by a heat shielding member, the boost converter (40) including a current sensor (43) and a capacitor (45) disposed following the first surface; and a case (30) that accommodates the fuel cell stack (20) and the boost converter (40) in a same space, wherein at least one of the current sensor (43) and the capacitor (45) is disposed on an upstream side from a middle of the coolant channel, in the direction in which the coolant channel extends.

摘要： A vehicle (100) includes a motor housing (90) accommodating motors (91a, 91b) for driving wheels, and a power control unit (2, 102, 202) fixed on the motor housing (90). The power control unit (2, 102, 202) includes: a stacked unit (40) in which multiple power modules (6) accommodating power semiconductor elements for electric power conversion and multiple coolers (46) are stacked; and reactors (4a, 4b). The stacked unit (40) is disposed in the case (20) of the power control unit (2, 102, 202) such that the stacking direction of the power modules (6) and the coolers (46) is directed toward the vehicle-longitudinal direction. The reactors (4a, 4b) are disposed in the case (20) so as not to overlap with the stacked unit (40) as viewed from the stacking direction.
