7. The work vehicle according to claim 6, wherein the radiator includes a fan that is disposed between the fuel cell and the electrical component in the horizontal direction and generates an air flow from a side of the electrical component toward a side of the fuel cell.
8. The work vehicle according to any one of claims 1 to 7, further comprising an air cleaner that cleans air supplied to the fuel cell, wherein the electrical component and the air cleaner are disposed overlapping in the horizontal direction orthogonal to the direction in which the fuel cell and the driver's seat are arranged.
9. The work vehicle according to any one of claims 1 to 8, further comprising: a first hood that covers the fuel cell; and a second hood that covers the electrical component.
10. The work vehicle according to any one of claims 1 to 9, further comprising a cabin disposed around the driver's seat, wherein the electrical component is disposed between the fuel cell and the cabin in the horizontal direction.

Description

TECHNICAL FIELD The present disclosure relatesto a work vehicle such as a tractor. BACKGROUND ART In recent years, there has been proposed a work vehicle such as a tractor using 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 driving an electric motor 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 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 electrical component disposed between the fuel cell and the driver's seat in the horizontal direction. BRIEF DESCRIPTION OF DRAWINGS [FIG. 1] FIG. 1 is a perspective view illustrating an embodiment of a work vehicle of the present disclosure.[FIG. 2] FIG. 2 is a front view of the work vehicle.[FIG. 3] FIG. 3 is a rear view of the work vehicle.[FIG. 4] FIG. 4 is a side view (right side view) of the work vehicle.[FIG. 5] FIG. 5 is a side view (left side view) of the work vehicle.[FIG. 6] FIG. 6 is a plan view of the work vehicle.[FIG. 7] FIG. 7 is a bottom view of the work vehicle.[FIG. 8] FIG. 8 is an exploded perspective view illustrating a portion of the work vehicle.[FIG. 9] FIG. 9 is a right side view of the work vehicle illustrating a state in which a hood, a cover, and a portion of a tank case of a tank unit are removed.[FIG. 10] FIG. 10 is a front view of a second radiator and a periphery thereof.[FIG. 11] FIG. 11 is a plan view of the second radiator and the periphery thereof.[FIG. 12] FIG. 12 is a perspective view of the second radiator and the periphery thereof as viewed obliquely from the rear right side.[FIG. 13] FIG. 13 is a perspective view of the second radiator and the periphery thereof as viewed obliquely from the front left side.[FIG. 14] FIG. 14 is a perspective view of a mounting frame as viewed obliquely from the front left side.[FIG. 15] FIG. 15 is a side view of the mounting frame and a periphery thereof as viewed from the left side. 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 that cools the fuel cell, an air cleaner for cleaning air supplied to the fuel cell, various electrical components connected to the battery and the controller, 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 electrical components connected to various electric components can be disposed by effectively utilizing a space on a vehicle body. <Effects of present disclosure> According to the present disclosure, electrical components 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.
