To load a fuel battery while suppressing expansion of hazardous area in a cargo transportation vessel where cargo hold is hazardous area.SOLUTION: A cargo transportation vessel includes: a hull; a hydrogen fuel tank for storing hydrogen fuel; a fuel battery power generation unit having a sealable casing and a fuel battery arranged inside it; and an electric power conversion device for supplying electric power generated by the fuel battery power generation unit to at least one of an electric motor for propulsion and an inboard electric power load. When an area from a portion positioned above the cargo hold in an upper deck of the hull to below a prescribed first height is stipulated as a hazardous place on a deck derived from the cargo, the hydrogen fuel tank is arranged in between front and back sides, i.e., from a front end to rear end of the cargo hold in the hull and the fuel cell electric power generation unit is arranged in between front and back sides, i.e., from the front end to rear end of the cargo hold and above the upper deck, with a section arranged with the fuel battery arranged evading the hazardous place on the deck.SELECTED DRAWING: Figure 1 【課題】貨物倉が危険場所である貨物運搬船において危険場所の拡張を抑えつつ燃料電池を搭載する。【解決手段】貨物運搬船は、船体と、水素燃料を貯蔵する水素燃料タンクと、密閉可能なケーシングとその内部に配置された燃料電池を有する燃料電池発電ユニットと、燃料電池発電ユニットで発電された電力を推進用電動機及び船内電力負荷のうち少なくとも一方へ供給する電力変換装置とを備える。船体の上甲板のうち貨物倉の上方に位置する部分から所定の第１高さ以下の区域を貨物に由来する甲板上危険場所と規定したときに、水素燃料タンクは船体において貨物倉の前端から後端までの前後間に配置され、燃料電池発電ユニットは、燃料電池が配置された区画が甲板上危険場所から退避した状態で、貨物倉の前端から後端までの前後間であって上甲板よりも上方に配置されている。【選択図】図１
