An ocean-going autonomous underwater vehicle powered by a polymer electrode membrane fuel cell system was completed by The Japan Agency for Marine-Earth Science and Technology. The 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 paper presents the test results of the fuel cell, storage system and the 317km sea test.

Long Time

The underwater platform which has enough ability to cruise globally and freely in vast deep sea will allow us to make the survey of entire oceans. We aim to develop an underwater platform which travels and surveys across entire oceans for the research into the global change, ocean-trench earthquake, and biodiversity and so on. We have developed the first prototype underwater platform or the long-range cruising autonomous underwater vehicle (LCAUV) named Urashima since 1998. The vehicle powered by a polymer electrolyte fuel cell system marked the world record of cruising distance of 317 kilometers in 2005. The vehicle has the following specifications: length; 10 m, weight; 10 tons, maximum depth ratings; 3500 m, maximum cruising speed; 3.2 knots, and endurance; 60 hours. This large vehicle has large user payload of a few hundreds kilograms. In 2007, we started research and development of the elemental technologies which will be utilizes for development of the second generation LCAUV to achieve cruising range of over 3000 kilometers. The technologies under research and development are power sources, navigation methods, communication methods, vehicle controllers, materials for body, and advanced sensors for highly resolution survey. The fuel cell and secondary battery hybrid system is had to improve at energy efficiency to generate electricity as possible for long time running with limited energy. A high accuracy inertial navigation system and an underwater positioning system being covered area of over 1000 km are under development. A synthesized aperture sonar is also under development.

This study aims to analyze the effect of an evaporator in a fuel cell system which uses oxygen as a fuel. The oxygen from a liquid storage tank flows to the evaporator in order to supply gaseous oxygen fuel to the fuel cell stack. The design of the evaporator has an effect on the temperature and mass flow rate of the gaseous oxygen being supplied to the stack, which results in a change in the performance of the fuel cell system. In order to evaluate the characteristics, several components such as an oxygen storage tank, evaporator, stack, etc. were modeled and the parameters of the evaporator simulated. Increasing the heat exchange area in an evaporator enhances the effect of heat transfer, but its cost and overheated supplying oxygen gas may have a negative effect on the performance of the system. It is important to evaluate the optimization of the evaporator in a fuel cell system to ensure the better performance of the system.
