The hydrogen station described in Non-Patent Document 1 includes a hydrogen supply area in which a dispenser that supplies fuel (hydrogen) to an automobile or the like and a canopy that covers the top of the dispenser are arranged. Further, in the hydrogen station described in Non-Patent Document 1, a building such as a showroom is arranged at the side of the hydrogen supply area.

(8) In this embodiment, since an air supply fan is provided in the opening U2 of the air supply path part 22 of the boundary member 20, the hydrogen explosion-proof specification of the fan forcibly exhausting the basement 50 can be avoided.

また、上記実施形態は、以下の態様に変更してもよい。
・上記実施形態においては、境界部材２０の排気経路部２１を、上方になるに従って、水平面に対する角度が小さくなる形状で構成した。境界部材２０の排気経路部２１の形状は、これに限定されない。 Moreover, you may change the said embodiment into the following aspects.
In the above-described embodiment, the exhaust path portion 21 of the boundary member 20 is configured to have a shape in which the angle with respect to the horizontal plane decreases as it goes upward. The shape of the exhaust path portion 21 of the boundary member 20 is not limited to this.

例えば、図４（ａ）に示すように、垂直断面が円弧形状の中空Ｓ３を有する曲面形状の排気経路部を備えた境界部材７０としてもよい。この場合、垂直断面が曲率の異なる円弧形状の中空が形成された部材を連接した境界部材としてもよい。
更に、図４（ｂ）に示すように、垂直断面が、水平部と垂直部とを交互に組み合わせた階段形状の中空Ｓ４を有する排気経路部を備えた境界部材８０としてもよい。 For example, as shown in FIG. 4A, the boundary member 70 may be provided with a curved exhaust path portion having a hollow S3 whose arc-shaped vertical section is circular. In this case, it is good also as a boundary member which connected the member in which the vertical cross section formed the circular arc-shaped hollow from which a curvature differs.
Furthermore, as shown in FIG. 4B, the vertical cross section may be a boundary member 80 including an exhaust path portion having a step-shaped hollow S4 in which horizontal portions and vertical portions are alternately combined.

・上記実施形態においては、境界部材２０は、排気経路部２１と給気経路部２２とを、水素供給エリアＨＡ１から境界部材２０を見て、前後に平行に並ぶような位置に配置する。境界部材２０における排気経路部２１と給気経路部２２との配置は、これに限られず、水素供給エリアＨＡ１から境界部材２０を見て左右に排気経路部２１と給気経路部２２とを並べた配置の構成としてもよい。また、境界部材２０は、排気経路部２１のみを備えた構造としてもよいし、中空を有しない建物４０の壁として構成してもよい。なお、前者の場合には、給気経路部２２の開口を、境界部材２０とは別に、居住エリアＲＡ１と反対側の水素供給エリアＨＡ１の地面に設けるようにしてもよい。   In the above-described embodiment, the boundary member 20 arranges the exhaust path portion 21 and the air supply path portion 22 at positions where they are aligned in parallel in the front-rear direction when viewing the boundary member 20 from the hydrogen supply area HA1. The arrangement of the exhaust path portion 21 and the air supply path portion 22 in the boundary member 20 is not limited to this. Alternatively, the arrangement may be different. Further, the boundary member 20 may have a structure including only the exhaust path portion 21 or may be configured as a wall of the building 40 that does not have a hollow. In the former case, the opening of the air supply path portion 22 may be provided on the ground of the hydrogen supply area HA1 opposite to the living area RA1 separately from the boundary member 20.

・上記実施形態においては、水素貯蔵エリアＨＡ２を地下室５０によって構成した。水素貯蔵エリアＨＡ２は、水素供給エリアＨＡ１の下方の領域であれば、地下に設けなくてもよい。例えば、水素供給エリアＨＡ１が２階以上に設置される場合には、水素貯蔵エリアＨＡ２を地上階等に設置してもよい。   In the above embodiment, the hydrogen storage area HA2 is configured by the basement 50. The hydrogen storage area HA2 may not be provided underground if it is a region below the hydrogen supply area HA1. For example, when the hydrogen supply area HA1 is installed on the second floor or higher, the hydrogen storage area HA2 may be installed on the ground floor or the like.
