Abstract

Alternative electrochemical power sources are under consideration for use In the Unmanned Underwater Vehicle (UUV) Prototype Program of the Defense Advanced Research Projects Agency. The current configuration uses a silver-zinc secondary battery to demonstrate the propulsion, structures, electronics, and mission systems of the UUV. An eight fold improvement in energy capacity can be realized, within the same volume, through various fuel cell and metal anode semi-cell options. A systems level analysis has been conducted to determine the overall energy capacity enhancement, vehicle performance, safety, cost/availability, and logistic considerations of these alternative electrochemical sources.
