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. This type of work vehicle also requires a radiator for cooling 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 radiator disposed side by side with the fuel cell; and a support member that supports the radiator, in which the support member includes a first support member connected to the vehicle body and the radiator, and a second support member connected to the fuel cell and the radiator. 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. DETAILED DESCRIPTION <Problems to be solved by present disclosure> In a fuel cell, since a cooling temperature is lower than that of an internal combustion engine and a heat generation amount increases as a load increases, a radiator with high cooling performance is required. When the size of the radiator is increased in order to enhance the cooling performance, the weight is also increased, and therefore strong support is required. An object of the present disclosure is to provide a work vehicle capable of firmly supporting a radiator. <Effects of present disclosure> According to the present disclosure, a radiator can be firmly supported. <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 radiator disposed side by side with the fuel cell; and a support member that supports the radiator, in which the support member includes a first support member connected to the vehicle body and the radiator, and a second support member connected to the fuel cell and the radiator. According to this configuration, the radiator can be firmly supported by the vehicle body and the fuel cell via the first and second support members. (2) The work vehicle according to (1) preferably further includes a fixed frame fixed to the vehicle body, in which the support member includes a third support member connected to the fixed frame and the radiator. According to this configuration, the radiator can be firmly supported by the fixed frame via the third support member. (3) In the work vehicle according to (2), preferably, an electrical component is attached to the fixed frame. With such a configuration, the radiator can be supported by using the fixed frame for attaching the electrical component. (4) In the work vehicle according to (3), preferably, the fixed frame is disposed on a side in the radiator where air is sucked. According to this configuration, since air at a relatively low temperature before passing through the radiator passes through the periphery of the electrical component attached to the fixed frame, the temperature rise of the electrical component can be suppressed. (5) In the work vehicle according to (4), preferably, the radi
