The fuel tank 6 in the storage unit 14 stores fuel so that the bottom of the hull 2 is positioned above the water surface when positioned below the bottom of the hull 2.
When the storage unit 14 is positioned below the bottom of the hull 2, the bottom of the hull 2 is positioned above the water surface due to the buoyancy of fuel (hydrogen) stored in the fuel tank 6 in the storage unit 14. Configured as follows.
　以上のように、収納部１４が航行中に船体２の船底よりも下方に位置し、収納部１４が船体２の船底よりも下方に位置したときに、船体２の船底が水面よりも上方に位置するように構成される、燃料電池船１では、航行中に船体２の船底が水面よりも上方に位置することから、航行中に船体２が受ける水による推進抵抗を低減させることができる。 As described above, when the storage unit 14 is positioned below the bottom of the hull 2 during navigation and the storage unit 14 is positioned below the bottom of the hull 2, the bottom of the hull 2 is above the water surface. In the fuel cell ship 1 configured to be positioned, the bottom of the hull 2 is positioned above the water surface during navigation, so that propulsion resistance due to water received by the hull 2 during navigation can be reduced.
　燃料電池船１の収納部１４は、略円柱状に構成される。燃料タンク６は、その軸心方向が船首尾方向（前後方向）に沿うように配置される。収納部１４は、船体２の船首部と船尾部とに亘るように構成される。収納部１４は、その軸心方向の長さが船体長の１／２の長さよりも長く構成される。収納部１４は、その軸心方向の長さが船体長の２／３の長さよりも長く構成される。 The storage unit 14 of the fuel cell ship 1 is configured in a substantially cylindrical shape.

The storage portion 14 is configured such that the length in the axial direction is longer than 2/3 of the hull length.
　以上のように、収納部１４の軸心方向が船首尾方向に沿うように収納部１４が配置される、燃料電池船１では、収納部１４の軸心方向が船首尾方向に沿うことから、航行中に収納部１４が受ける水による推進抵抗を低減させることができる。
　また、燃料電池船１では、収納部１４が略円柱状に構成されることから、収納部１４の強度を比較的高いものとすることができる。 As described above, in the fuel cell ship 1 in which the storage unit 14 is arranged so that the axial center direction of the storage unit 14 is along the bow-stern direction, the axial center direction of the storage unit 14 is along the bow-stern direction. Propulsion resistance due to water received by the storage unit 14 during navigation can be reduced.
Moreover, in the fuel cell ship 1, since the storage part 14 is comprised by substantially cylindrical shape, the intensity | strength of the storage part 14 can be made comparatively high.

　以上のように、収納部１４は、その前端部が半球状に形成されて構成される、燃料電池船１では、収納部１４の前端部が半球状に形成されることから、航行中に収納部１４が受ける水による推進抵抗を低減させることができる。 As described above, the storage portion 14 is configured so that the front end portion thereof is formed in a hemispherical shape. In the fuel cell ship 1, the front end portion of the storage portion 14 is formed in a hemispherical shape. Propulsion resistance due to water received by the section 14 can be reduced.

The fuel tank 6 is stored in the storage unit 14 so as to be positioned at a substantially central portion of the storage unit 14 in the bow-stern direction. The fuel tank 6 is stored in the storage portion 14 so as to be positioned at a substantially central portion in the bow-stern direction of the hull 2. The storage unit 14 is disposed so that the fuel cell 5 and the battery 7 are close to each other, the battery 7 and the fuel tank 6 are close to each other, and the fuel tank 6 and the motor 4 are close to each other.
　以上のように、燃料タンク６が収納部１４における船首尾方向の略中央部に位置するように収納部１４に収納される、燃料電池船１では、燃料タンク６が収納部１４における船首尾方向の略中央部に位置するように収納部１４に収納されることから、船体２の前後のバランスを安定させることができる。 As described above, in the fuel cell ship 1 in which the fuel tank 6 is stored in the storage unit 14 so that the fuel tank 6 is positioned at a substantially central portion of the storage unit 14 in the bow-stern direction, the fuel tank 6 is in the bow-stern direction in the storage unit 14. Since it is accommodated in the accommodating part 14 so that it may be located in the approximate center part, the balance before and behind the hull 2 can be stabilized.

　したがって、燃料電池１によれば、高さ制限に該当した状態を回避して、高さ制限のある場所を航行することができる。 As described above, the fuel cell ship 1 is configured so that the vertical position of the hull 2 relative to the water surface can be changed by moving the storage unit 14 (fuel tank 6) up and down, which corresponds to the height restriction from the water surface. In this case, the state corresponding to the height restriction can be avoided by moving the storage portion 14 (fuel tank 6) upward and changing the vertical position of the hull 2 downward.
Therefore, according to the fuel cell 1, it is possible to navigate a place with a height restriction while avoiding a state corresponding to the height restriction.
　また以上のように、収納部１４が船体２の船底よりも下方の位置から水面上に露出する位置に移動可能に構成され、収納部１４が水面上に露出するとき、船体２の船底が水中に位置する、燃料電池船１では、収納部１４が水面上に露出させて、船体２の船底を水中に位置させることにより、船体２内への出入口を船体２へ乗降し易い位置に下げることができる。

　図２３から図２４に示すように、燃料電池船１は、船体２と、プロペラ３と、モータ４と、燃料電池５と、燃料タンク６と、バッテリ７と、制御装置９（図１８、図２２参照）と、収納部１４と、舵１５と、を備える。 As shown in FIGS. 23 to 24, the fuel cell ship 1 includes a hull 2, a propeller 3, a motor 4, a fuel cell 5, a fuel tank 6, a battery 7, and a control device 9 (FIG. 18, FIG. 22), a storage portion 14, and a rudder 15.
　燃料電池船１では、モータ４と、燃料タンク６と、が船外に配置される。 In the fuel cell ship 1, the motor 4 and the fuel tank 6 are disposed outside the ship.
　以上のように、モータ４と、燃料タンク６と、が船体２外に配置される、燃料電池船１では、モータ４と燃料電池５と燃料タンク６とが船体２外に配置されることから、モータ４と燃料タンク６とを船体２内に配置するためのスペースが不要となる。
　したがって、燃料電池船１によれば、船体２内の居住性を向上させることができる。
　また、燃料電池船１では、モータ４が船体２外に配置されることから、モータ４の駆動音が騒音として船体２内（キャビン内）に聞こえることを抑制することができる。 As described above, in the fuel cell ship 1 in which the motor 4 and the fuel tank 6 are disposed outside the hull 2, the motor 4, the fuel cell 5, and the fuel tank 6 are disposed outside the hull 2. The space for arranging the motor 4 and the fuel tank 6 in the hull 2 becomes unnecessary.
Therefore, according to the fuel cell ship 1, the habitability in the hull 2 can be improved.
Further, in the fuel cell ship 1, since the motor 4 is disposed outside the hull 2, it is possible to suppress the driving sound of the motor 4 from being heard as noise in the hull 2 (in the cabin).
　燃料電池船１の収納部１４は、金属素材で構成されるケース（容器）であり、モータ４と、燃料タンク６と、を覆うように収納する。収納部１４には、モータ４と、燃料タンク６と、が比較的近接するように収納される。モータ４、および燃料タンク６は、収納部１４に収納されて一体的に構成される。 The storage unit 14 of the fuel cell ship 1 is a case (container) made of a metal material and stores the motor 4 and the fuel tank 6 so as to cover them. The storage unit 14 stores the motor 4 and the fuel tank 6 so as to be relatively close to each other. The motor 4 and the fuel tank 6 are housed in the housing portion 14 and configured integrally.
　以上のように、収納部１４を備える燃料電池船１では、モータ４が船体２外に配置されるとともに収納部１４に収納されることから、モータ４の駆動音が騒音として船体２内（キャビン内）に聞こえることを確実に抑制することができる。 As described above, in the fuel cell ship 1 provided with the storage portion 14, the motor 4 is disposed outside the hull 2 and stored in the storage portion 14, so that the driving sound of the motor 4 is generated as noise in the hull 2 (cabin ) Can be reliably suppressed.
　燃料電池船１のプロペラ３は、収納部１４の後端部に設けられる。プロペラ３と、モータ４と、燃料タンク６と、が比較的近接するように配置される。プロペラ３、モータ４、および燃料タンク６が、一体的に構成される。 The propeller 3 of the fuel cell ship 1 is provided at the rear end of the storage unit 14. The propeller 3, the motor 4, and the fuel tank 6 are disposed so as to be relatively close to each other. The propeller 3, the motor 4, and the fuel tank 6 are integrally formed.
　以上のように、プロペラ３が収納部１４の後端部に配置されて、モータ４と近接するように配置される、燃料電池船１では、プロペラ３がモータ４と近接するように配置されることから、モータ４が船体２内に配置されるものに比べて、モータ４の動力をプロペラ３に伝達するためのギア等（トランスミッション）を簡易な構成とすることができる。 As described above, in the fuel cell ship 1 in which the propeller 3 is disposed at the rear end portion of the storage portion 14 and disposed close to the motor 4, the propeller 3 is disposed close to the motor 4. As a result, the gear (transmission) for transmitting the power of the motor 4 to the propeller 3 can be made simpler than that in which the motor 4 is disposed in the hull 2.
　燃料電池船１は、収納部１４を支持するアーム１１を備える。
　燃料電池船１のアーム１１は、前後二個ずつ備えられる。アーム１１は、船体２の底部にそれぞれ二個ずつ並べて配置される。アーム１１は、その基端部が船体２の底部に取付けられて、下方に延出するように構成される。 The fuel cell ship 1 includes an arm 11 that supports the storage unit 14.
Two arms 11 of the fuel cell ship 1 are provided at the front and rear. Two arms 11 are arranged side by side at the bottom of the hull 2. The arm 11 is configured such that its proximal end is attached to the bottom of the hull 2 and extends downward.
　燃料電池船１の収納部１４は、アーム１１の先端部に設けられる。収納部１４は、水中に位置する。収納部１４は、船体２の船底（船体２の下端）よりも下方に位置する。 The storage part 14 of the fuel cell ship 1 is provided at the tip of the arm 11. The storage unit 14 is located in the water. The storage unit 14 is located below the bottom of the hull 2 (the lower end of the hull 2).
　以上のように、収納部１４が船底２の船底の下方に位置する、燃料電池船１では、重量物である収納部１４が船体２の船底の下方に位置することから、燃料電池船１の重心が低くなり、航行中に揺れが生じることを抑制することができる。
　したがって、燃料電池船１によれば、航行中における船体２内の居住性を向上させることができる。
　また、燃料電池船１では、収納部１４が船体２の船底の下方に位置して船体２外に配置されることから、船体２内の居住性を向上させることができる。
　また、燃料電池船１では、収納部１４が船体２の船底の下方に位置して水中に位置することから、収納部１４に収納される燃料タンク６から燃料漏れが生じたときの船体２内の危険性を低減することができる。 As described above, in the fuel cell ship 1 in which the storage unit 14 is positioned below the bottom of the ship bottom 2, the heavy storage unit 14 is positioned below the bottom of the hull 2. The center of gravity is lowered, and the occurrence of shaking during navigation can be suppressed.
Therefore, according to the fuel cell ship 1, the habitability in the hull 2 during navigation can be improved.
Further, in the fuel cell ship 1, since the storage portion 14 is located below the ship bottom of the hull 2 and disposed outside the hull 2, the comfort in the hull 2 can be improved.
Further, in the fuel cell ship 1, the storage portion 14 is located below the bottom of the hull 2 and located in the water, so that the inside of the hull 2 when the fuel leaks from the fuel tank 6 stored in the storage portion 14. Can reduce the risk.
　燃料電池船１の収納部１４は、船体２における船首尾方向の中途部に配置される。収納部１４は、船体２の船首と船尾との間に位置するように配置される。 The storage portion 14 of the fuel cell ship 1 is disposed in the midway portion of the hull 2 in the bow-stern direction. The storage unit 14 is disposed so as to be positioned between the bow and the stern of the hull 2.
　以上のように、収納部１４が船体２における船首尾方向の中途部に配置される、燃料電池船１では、収納部１４が船体２における船首尾方向の中途部に配置されることから、船体２の前後のバランスを安定させることができる。 As described above, in the fuel cell ship 1 in which the storage portion 14 is disposed in the midway portion of the bow 2 in the hull 2, the storage portion 14 is disposed in the midway portion of the bow 2 in the bow 2. The balance before and after 2 can be stabilized.
　燃料電池船１の収納部１４は、略円柱状に構成される。収納部１４は、その軸心方向が船首尾方向（前後方向）に沿うように配置される。 The storage unit 14 of the fuel cell ship 1 is configured in a substantially cylindrical shape. The accommodating part 14 is arrange | positioned so that the axial center direction may follow a bow / tail direction (front-back direction).
　以上のように、収納部１４の軸心方向が船首尾方向に沿って平行するように収納部１４が配置される、燃料電池船１では、収納部１４の軸心方向が船首尾方向に平行することから、航行中に収納部１４が受ける水による推進抵抗を低減させることができる。
　また、燃料電池船１では、収納部１４が略円柱状に構成されることから、収納部１４の強度を比較的高いものとすることができる。 As described above, in the fuel cell ship 1 in which the storage unit 14 is arranged so that the axial center direction of the storage unit 14 is parallel to the bow-stern direction, the axial direction of the storage unit 14 is parallel to the bow-stern direction. Therefore, the propulsion resistance due to the water received by the storage unit 14 during navigation can be reduced.
Moreover, in the fuel cell ship 1, since the storage part 14 is comprised by substantially cylindrical shape, the intensity | strength of the storage part 14 can be made comparatively high.
　燃料電池船１の収納部１４は、その前端部（先端部）が半球状に形成されて構成される。収納部１４は、魚雷型に構成される。 The storage unit 14 of the fuel cell ship 1 is configured such that its front end (tip) is formed in a hemispherical shape. The storage unit 14 is configured as a torpedo.
　以上のように、収納部１４は、その前端部が半球状に形成されて構成される、燃料電池船１では、燃料タンク６の前端部が半球状に形成されることから、航行中に収納部１４が受ける水による推進抵抗を低減させることができる。 As described above, in the fuel cell ship 1, the front end portion of the fuel tank 6 is formed in a hemispherical shape in the fuel cell ship 1. Propulsion resistance due to water received by the section 14 can be reduced.
　燃料電池船１の収納部１４は、船体２の船首部と船尾部とに亘るように構成される。収納部１４は、その軸心方向の長さが船体長の１／２の長さよりも長く構成される。収納部１４は、その軸心方向の長さが船体長の２／３の長さよりも長く構成される。 The storage unit 14 of the fuel cell ship 1 is configured to extend over the bow and stern of the hull 2. The storage portion 14 is configured such that its axial length is longer than half the hull length. The storage portion 14 is configured such that the length in the axial direction is longer than 2/3 of the hull length.
　以上のように、収納部１４の軸心方向の長さが船体長の１／２の長さよりも長く収納部１４が構成される、燃料電池船１では、収納部１４を比較的大きく構成することができ、収納部１４に収納される燃料タンク６の燃料の総貯留量を保持したままで搭載する燃料タンク６の個数を少なくすることができる。
　したがって、燃料電池船１によれば、燃料タンク６の個数を少なくして燃料タンク６が連結される箇所を少なくし、当該燃料タンク６が連結される箇所から燃料漏れが生じる機会を低減させることができる。 As described above, in the fuel cell ship 1 in which the storage unit 14 is configured such that the length of the storage unit 14 in the axial direction is longer than ½ the hull length, the storage unit 14 is configured to be relatively large. The number of fuel tanks 6 to be mounted can be reduced while maintaining the total amount of fuel stored in the fuel tank 6 stored in the storage unit 14.
Therefore, according to the fuel cell ship 1, the number of fuel tanks 6 is reduced to reduce the number of locations where the fuel tanks 6 are connected, thereby reducing the chance of fuel leakage from the locations where the fuel tanks 6 are connected. Can do.
　燃料電池船１の舵１５は、収納部１４に設けられる。舵１５は、収納部１４の後部に配置される。 The rudder 15 of the fuel cell ship 1 is provided in the storage unit 14. The rudder 15 is disposed at the rear part of the storage unit 14.
　燃料電池船１の制御装置９は、操作部１０ａが操作されることによって、舵１５の動作を制御する。制御装置９は、舵１５の向き（回動角度）を表示部１０ｂに表示させる。 The control device 9 of the fuel cell ship 1 controls the operation of the rudder 15 by operating the operation unit 10a. The control device 9 displays the direction (rotation angle) of the rudder 15 on the display unit 10b.
　図２５に示すように、燃料電池船１の収納部１４は、外壁１４ａと内壁１４ｂとを有する二重構造で構成することもできる。
　このとき、収納部１４は、外壁１４ａと内壁１４ｂとの間に所定の空間が形成さて構成される。収納部１４は、内壁１４ｂ内にモータ４および燃料タンク６を収納し、外壁１４ａと内壁１４ｂとの間の空間に空気を貯留する。 As shown in FIG. 25, the storage portion 14 of the fuel cell ship 1 can also be configured as a double structure having an outer wall 14a and an inner wall 14b.
At this time, the storage unit 14 is configured by forming a predetermined space between the outer wall 14a and the inner wall 14b. The accommodating part 14 accommodates the motor 4 and the fuel tank 6 in the inner wall 14b, and stores air in the space between the outer wall 14a and the inner wall 14b.
　以上のように、燃料電池船１の収納部１４が、外壁１４ａと内壁１４ｂとを有する二重構造で構成され、内壁１４ｂ内にモータ４および燃料タンク６を収納する、燃料電池船１では、例えば、収納部１４が障害物に接触して損傷した場合であっても、外壁１４ａによって、内壁１４ｂに収納されるモータ４および燃料タンク６等を保護することができる。 As described above, in the fuel cell ship 1 in which the storage portion 14 of the fuel cell ship 1 is configured with a double structure having the outer wall 14a and the inner wall 14b, and the motor 4 and the fuel tank 6 are stored in the inner wall 14b, For example, even when the storage portion 14 is damaged by contact with an obstacle, the motor 4 and the fuel tank 6 stored in the inner wall 14b can be protected by the outer wall 14a.
　次に、図２６から図２７に記載の燃料電池船１について説明する。
　なお、図２６から図２７に記載の燃料電池船１の説明では、図１６から図２５に記載の燃料電池船１と同様の構成の部分については適宜省略し、図１６から図２５に記載の燃料電池船１の構成と異なる部分を中心に説明する。 Next, the fuel cell ship 1 shown in FIGS. 26 to 27 will be described.

　収納部１４は、アーム１１の先端部に設けられて、船体２の左右にそれぞれ配置される。燃料タンク６は、船体２を中心にして左右対称となる位置に配置される。 In the fuel cell ship 1, two storage portions 14 (a pair of left and right) are provided, and two arms 11 are provided on each of the left and right sides.
The two left arms 11 support the left storage portion 14. The two right arms 11 support the right accommodating portion 14. Two arms 11 are arranged side by side on the left side and the right side of the hull 2.
The storage portions 14 are provided at the distal end portions of the arms 11 and are respectively disposed on the left and right sides of the hull 2. The fuel tank 6 is disposed at a position that is symmetrical with respect to the hull 2.

　燃料電池船１は、左右のプロペラ３の回転数または回転方向がそれぞれ異なった状態で航行可能に構成される。 The left and right motors 4 of the fuel cell ship 1 are configured to be independently drivable so that their rotation speeds or rotation directions are different. When the left and right motors 4 are independently driven, the left and right propellers 3 are configured to be drivable so that their rotation speeds or rotation directions are different.
The fuel cell ship 1 is configured to be able to navigate in a state where the rotation speeds or rotation directions of the left and right propellers 3 are different from each other.
