A moving body is equipped with fuel cells structured to have multiple corners. The fuel cells have a fuel gas exhaust port formed to discharge a fuel gas, which is subjected to an electrochemical reaction at anodes of the fuel cells, out of the fuel cells. The fuel cells are arranged to be inclined to a horizontal plane to position a front side of the fuel cells in a forward direction of the moving body higher than an opposite side of the fuel cells in the forward direction of the moving body and are provided to locate a specific corner closest to the fuel gas exhaust port of the fuel cells among the multiple corners as a lowermost point. This arrangement enables water produced at the anodes of the fuel cells to be efficiently discharged from the fuel cells by taking advantage of the gravity, while the moving body moves on a slope.
