## Abstract

An ion exchanger comprises an ion exchange cartridge, and an ion exchanger bracket for connecting the ion exchange cartridge to a cooling water path to thereby hold the ion exchange cartridge so as to be freely removed. The ion exchanger bracket is provided at a position closer to the front end portion of the fuel cell vehicle, the position being on the side surface of the sub-frame. The cooling water path, connected to the ion exchanger bracket, is arranged so as to reach the motor room, penetrating the sub-frame. Also, because the ion exchanger is mounted in a space surrounded by the rear side of the bumper and an inner fender covering the rear side of the fender and a tire house, the ion exchange cartridge becomes available to be taken out when a part on the front side of the inner fender is removed.

## Claims

### Claim at position 1

-4. (canceled)

### Claim 5

An ion exchanger for a fuel cell vehicle, for removing ions in cooling water flowing in a cooling water path equipped to a fuel cell mounted in the vehicle, wherein
the ion exchanger, which requires regular replacement, is mounted in a space surrounded by a bumper and a fender, both in a forward direction of the vehicle.

### Claim 6 (depends on 5)

The ion exchanger for a fuel cell vehicle according to claim 5, wherein the place where the ion exchanger is mounted is a space surrounded by a bumper in a front direction of the vehicle and an inner fender covering the fender and an inner side of the fender.

### Claim 7 (depends on 5)

The ion exchanger for a fuel cell vehicle according to claim 5, wherein
the ion exchanger comprises
an ion exchange cartridge where ion exchange resin is filled, and
an ion exchanger bracket for connecting the ion exchange cartridge to the cooling water path to thereby hold the ion exchange cartridge so as to be freely removed.

### Claim 8 (depends on 7)

The ion exchanger for a fuel cell vehicle according to claim 7, wherein, in removing the ion exchange cartridge, an inner fender covering an inner side of the fender is removed and taken out.

### Claim 9 (depends on 7)

The ion exchanger for a fuel cell vehicle according to claim 7, wherein, in removing the ion exchanger cartridge, an ion exchanger plug to be fitted in the ion exchange racket to block the cooling water path is mounted on the ion exchanger bracket.
