The PEM Fuel Cell System for Autonomous Underwater Vehicles

Various types of autonomous underwater vehicles (AUVs) have been developed and are used for conventional surveys due to their small size. Large AUVs are also being developed that are equipped with high technology computers, high-precision navigation systems, and efficient power sources. One ocean-going AUV powered by a polymer electrode membrane fuel cell system was completed by The Japan Agency for Marine-Earth Science and Technology. Its fuel cell system generates 4kW of electric power for the control electronics and propulsion system. Hydrogen gas is stored under low pressure in the metal hydride. Heat generated by the fuel cell is used to discharge hydrogen gas into the metal hydride. This article proposes one method in which to equip the proton exchange membrane fuel cell with storage devices for fuel and oxidizer, and a heat transfer device using the new generation AUV as its power source. Test results of the fuel cell, storage system and the 317 km Suruga Basin sea test are presented in this article.
