## Abstract

A fuel cell vehicle comprising: a hydrogen tank which is mounted on the vehicle so as to have a center axis generally parallel to a front/rear direction of the vehicle; a high-voltage electric component which is positioned either forward or rearward of the hydrogen tank and which operates on high voltage; an aftercooler placed between the hydrogen tank and the high-voltage electric component to cool compressed air; and a fuel cell stack which is supplied with the cooled compressed air.

## Claims

### Claim 1

A fuel cell vehicle comprising:
a hydrogen tank which is mounted on the vehicle so as to have a center axis generally substantially parallel to a front/rear direction of the vehicle;
a high-voltage electric component which is positioned either forward or rearward of the hydrogen tank and which operates on high voltage;
an aftercooler placed between the hydrogen tank and the high-voltage electric component on a common plane, wherein the aftercooler, the hydrogen tank and the high-voltage electric component are in the common plane, and the common plane is substantially parallel to the front/rear direction of the vehicle, wherein the high-voltage electric component is adapted to cool compressed air; and
a fuel cell stack which is supplied with the cooled compressed air.

### Claim 2 (depends on 1)

The fuel cell vehicle in accordance with claim 1, further comprising
a front room formed forward of a cabin, wherein
the high-voltage electric component is housed in the front room, and
the hydrogen tank is positioned rearward of the high-voltage electric component.

### Claim 3 (depends on 2)

The fuel cell vehicle in accordance with claim 2, wherein
the high-voltage electric component is an air compressor for feeding compressed air into the aftercooler, and
the fuel cell stack is housed in the front room,
the fuel cell vehicle further comprising an oxidizing gas supply path which is connected to a rear face of the fuel cell stack and which allows the cooled compressed air to flow therethrough.

### Claim 4 (depends on 3)

The fuel cell vehicle in accordance with claim 3, wherein
the air compressor is placed downward of the fuel cell stack.

### Claim 5 (depends on 1)

The fuel cell vehicle in accordance with claim 1, wherein
the high-voltage electric component is an air compressor for feeding compressed air into the aftercooler.

### Claim 6 (depends on 1)

The fuel cell vehicle in accordance with claim 1, wherein
the aftercooler is mounted in such an inclined posture that its bottom face intersects the front/rear direction.

### Claim 7 (depends on 1)

The fuel cell vehicle in accordance with claim 1, further comprising
a center tunnel which is an under-floor space formed by swelling of a floor of a cabin of the fuel cell vehicle, wherein
the hydrogen tank is placed within the center tunnel.
