JAMSTEC(日本海洋地球科学技术厅)和MHI(三菱重工株式会社)自1998年以来一直在开发AUV(自主式水下机器人)“Urashima”。长距离巡航的AUV通常需要高能量密度和高能效的AIP(空气独立推进)电源。燃料电池是小型水下航行器首选的AIP动力源，而PEFC(聚合物电解质燃料电池)已被用于“Urashima”号。据了解，燃料电池的一个主要主题是储存氢气，金属氢化物储存已经被“Urashima”采用为一种更安全的储存氢气的方法。2002年夏天，“乌拉什岛”号自主式水下航行器使用大容量锂离子充电电池成功完成了132.5公里的自主长途巡航。同时，为了扩大S号的巡航里程，开发了带有金属氢化物储氢系统的闭合循环PEFC(聚合物电解质燃料电池)系统作为替代AIP电源。2002年冬季，闭路循环的PEFC系统取代了锂离子可充电电池，成为“Urashima”的主要动力源。“Urashima”号凭借其新的动力源(闭合循环PEFC系统)在2003年夏季实现了世界上第一次也是最深的燃料电池动力源下潜，并于2004年春季完成了220公里的自主巡航。在海上试验中，采用金属氢化物储氢系统的燃料电池系统工作正常，并验证了水下燃料电池的运行。向车辆供电和向燃料电池系统供应氢气都没有问题。“Urashima”号将在即将到来的试验机会中进行AUV 300公里巡航的世界纪录。
JAMSTEC (Japan Agency for Marine-Earth Science and Technology) and MHI (Mitsubishi Heavy Industries, Ltd.) have been developing the AUV (Autonomous Underwater Vehicle) "Urashima" since 1998. Long-distance cruising AUVs generally need an AIP (Air Independent Propulsion) power source characterized by high-energy density and high-energy efficiency. Fuel cells are the preferred AIP power source for small underwater vehicles and PEFC (Polymer Electrolyte Fuel Cell) have been adopted for "Urashima". It is understood that one of the main themes with fuel cell is storing the hydrogen, the metal hydride storage has been adopted for "Urashima" as a safer method of storing the hydrogen. In summer of 2002 the AUV "Urashima" successfully completed an autonomous 132.5 km long-distance cruise using large capacity lithium-ion rechargeable battery. In the meantime, a Closed Cycle PEFC (Polymer Electrolyte Fuel Cell) system with a metal hydride hydrogen storage system was developed as an alternative AIP power source in order to extend "Urashima"'s cruising range. The lithium-ion rechargeable battery was replaced by the Closed Cycle PEFC system and this system became the main power source of "Urashima" in winter of 2002. "Urashima", with its new power source (the Closed Cycle PEFC system) achieved the world's first and deepest fuel cell power source dive in summer of 2003 and completed an autonomous cruise of 220 km in spring of 2004. In sea trials, the fuel cell system with metal hydride hydrogen storage system worked adequately and underwater fuel cell operation was verified. There were no problem in supplying power to the vehicle and supplying hydrogen to fuel cell system. "Urashima" will carry out the AUV world record 300 km cruising at upcoming trial opportunity.
