A fuel cell system () in which, at the time of starting up a first fuel cell set () and a second fuel cell set (), one of a first air supply unit () or a second air supply unit () is driven and then the another air supply units is driven so that electric power of the another air supply units reaches a peak after an output voltage of the one of the fuel cell stacks reaches the first output value.

Fuel cell system and control method at time of starting-up fuel cell system

An electric power conversion device is provided with a case () which includes: a first member () having a first region () defining therein a first passage () in which a cooling medium flows, and a second region () disposed on a side of the first region; and a second member () disposed so as to at least partly overlap with the second region as seen from a direction orthogonal to the second region in a spaced apart relationship to the second region, and internally defining a second passage () connected to the first passage. A reactor () is positioned in the first region, and a switching device () is positioned on the surface of the second member facing away from the first member while a capacitor () is positioned between the second member and the second region of the first member.

Electric power conversion device

An electric power conversion device is provided with a case () including a mounting portion () extending along a plane defined by a first direction and a second direction that are orthogonal to each other, and a side wall () provided along a periphery of the mounting portion, a primary side connection portion () and a secondary side connection portion () provided on the case, a plurality of reactors arranged along the second direction in the case and connected in parallel to one another, and a switching unit including a plurality of switching devices positioned in the case on one side of the reactors in the first direction, arranged along the first direction, and respectively connected to the reactors.

A capacitor unit includes a casing, a heat sink, a heat radiation sheet, and a notch. The casing accommodates the capacitors. The casing includes a positive electrode terminal block and a negative electrode terminal block. The heat sink is provided on the casing in a stacking direction. The heat radiation sheet is made of insulation material and is sandwiched in the stacking direction between the casing and the heat sink to cover the positive electrode terminal block and the negative electrode terminal block. The notch is provided in at least one of the casing and the heat radiation sheet between the negative electrode terminal block and the positive electrode terminal block. The notch passes through the at least one of the casing and the heat radiation sheet along a plain substantially perpendicular to the stacking direction to separate the negative electrode terminal block and the positive electrode terminal block.

Capacitor unit and capacitor casing structure

A capacitor arrangement structure includes a casing, a housing, and a heat sink. The casing accommodates a capacitor. The casing includes a casing bottom. The housing includes a bottom wall. The housing has a height from the bottom wall which includes an inner surface and an outer surface opposite to the inner surface in a height direction. The casing is mounted on the inner surface so that the casing bottom opposes a mounting surface in the inner surface. The heat sink includes a heat sink top. The heat sink is provided on the outer surface of the bottom wall not to overlap the casing viewed along the height direction. The heat sink top opposes the outer surface. A distance between the casing bottom and the mounting surface in the height direction is smaller than a distance between the heat sink top and the mounting surface in the height direction.
