水素燃料電池の実験船に検査証　日本初、国交省から取得―東京海洋大

　東京海洋大は２４日、実験船「らいちょうＮ」（９．１トン、１２人乗り）が水素燃料電池とリチウムイオン２次電池だけで運航できる船として、日本で初めて船舶検査証書を得たと発表した。この証書は自動車の車検証に相当し、国土交通省が交付する。
　同大の大出剛特任教授は文部科学省で記者会見し、「燃料電池船が実用レベルで走れることが示され、普及につながる」と話した。２種類の電池を組み合わせたハイブリッド制御システムや安全対策技術は、大手ガス関連企業・岩谷産業などが来年の大阪・関西万博で運航を目指す客船（約１７０トン、約１５０人乗り）に生かされているという。（2024/07/24-18:07）

A Tokyo university said Wednesday that its Raicho N has become the first ship powered only by hydrogen fuel cell and lithium-ion secondary battery systems that was certified to have passed a mandatory ship inspection in Japan.
   The transport ministry issued the ship inspection certificate for Tokyo University of Marine Science and Technology's 9.1-ton experimental vessel, capable of carrying 12 people.
   "It has been demonstrated that the fuel cell ship can operate at a practical level," Tsuyoshi Ode, specially appointed professor of the university, told a press conference, showing expectations for widespread use of such ships.
   The hybrid control system combining the two types of power systems and the safety technology will be utilized for a passenger boat capable of carrying 150 people that gas supplier Iwatani Corp. and others plan to operate at the 2025 World Exposition in the western city of Osaka.
   The hydrogen fuel cell system of the Raicho N is the same as the one used in Toyota Motor Corp.'s Mirai car. It requires three tanks of high-pressure hydrogen gas at room temperature.
