  3. The work vehicle according to claim 2, wherein the radiator includes a fan that is disposed between the fuel cell and the air cleaner in the horizontal direction and generates an air flow from a side of the air cleaner toward a side of the fuel cell.
  4. The work vehicle according to claim 2 or 3, further comprising a support member that supports the air cleaner, wherein the support member is connected to the radiator and the air cleaner.
  5. The work vehicle according to any one of claims 1 to 4, wherein the air cleaner includes an intake port of air facing downward.
  6. The work vehicle according to any one of claims 1 to 5, wherein the air cleaner includes a suction port of air at a lower portion and a discharge port of air at an upper portion.
  7. The work vehicle according to any one of claims 1 to 6, wherein the air cleaner has a dimension in a vertical direction larger than a dimension in the horizontal direction.
  8. The work vehicle according to any one of claims 1 to 7, wherein the vehicle body includes a first hood that covers the fuel cell and a second hood that covers the air cleaner.
  9. The work vehicle according to any one of claims 1 to 8, further comprising a cabin disposed around the driver's seat, wherein the air cleaner is disposed between the cabin and the fuel cell in the horizontal direction.

Description

TECHNICAL FIELD The present disclosure relates to a work vehicle such as a tractor. BACKGROUND ART In recent years, there has been proposed a work vehicle such as a tractor including a fuel cell that generates electric power using gaseous fuel such as hydrogen gas, instead of an internal combustion engine using fossil fuel from the viewpoint of protecting the global environment, and an electric motor driven by the generated electric power. For example, Patent Literature 1 discloses a work vehicle in which a driver's seat and a hood are installed on a vehicle body, and a battery that accumulates electricity generated by a fuel cell and a controller that controls an electric motor are housed in the hood together with the fuel cell. CITATION LIST [PATENT LITERATURE] PATENT LITERATURE 1: Japanese Laid-Open Patent Publication No. 2023-013187 SUMMARY OF THE INVENTION A work vehicle according to one aspect of the present disclosure includes: a vehicle body; a fuel cell installed on the vehicle body; a driver's seat installed on the vehicle body aligning with the fuel cell in a horizontal direction; and an air cleaner that is disposed between the fuel cell and the driver's seat in the horizontal direction and cleans air supplied to the fuel cell.

DETAILED DESCRIPTION <Problems to be solved by present disclosure> In a work vehicle on which a fuel cell is installed, not only a battery and a controller but also a radiator for cooling the fuel cell, an air cleaner for cleaning air supplied to the fuel cell, various electrical components connected to the battery and the controller via cables, and the like are required, and they need to be appropriately disposed in a limited space on a vehicle body. An object of the present disclosure is to provide a work vehicle in which an air cleaner, which is a component attached to a fuel cell, can be disposed by effectively utilizing a space on a vehicle body. <Effects of present disclosure> According to the present disclosure, an air cleaner can be disposed by effectively utilizing a space on a vehicle body. <Outline of embodiment of present disclosure> Hereinafter, an outline of an embodiment of the present disclosure will be listed and described. (1) A work vehicle according to an embodiment of the present disclosure includes: a vehicle body; a fuel cell installed on the vehicle body; a driver's seat installed on the vehicle body aligning with the fuel cell in a horizontal direction; and an air cleaner that is disposed between the fuel cell and the driver's seat in the horizontal direction and cleans air supplied to the fuel cell. According to this configuration, in the work vehicle driven by the fuel cell, the air cleaner can be disposed by effectively utilizing the space between the fuel cell and the driver's seat.(2) The work vehicle according to (1) preferably further includes a radiator between the fuel cell and the driver's seat in the horizontal direction, in which the air cleaner is disposed on a side in the radiator where air is sucked. According to this configuration, air with less contamination at a relatively low temperature before passing through the radiator can be taken into the air cleaner.(3) In the work vehicle according to (2), preferably, the radiator includes a fan that is disposed between the fuel cell and the air cleaner in the horizontal direction and generates an air flow from a side of the air cleaner toward a side of the fuel cell.(4) The work vehicle according to (2) or (3) preferably further includes a support member that supports the air cleaner, in which the support member is connected to the radiator and t
