Energy Conversion of JP-10 Fuel

The United States Navy has a critical need for improved power systems for unmanned underwater vehicle (UUV) systems. Power and energy density are critically deficient in current UUV platforms, and limit mission time and capability of current systems. Tethered systems and battery powered systems will not meet the mission profiles of next generation UUVs (including persistent surveillance, mine detection and anti-submarine missions). Achieving high power density at all levels will greatly enhance future UUV capabilities. In this SBIR project, NexTech Materials and its subcontractor (Plug Power) will design, develop and demonstrate a compact solid oxide fuel cell system that will provide kilowatts of power for UUV propulsion and other mission needs. For mission durations of at least 60 hours, the power system will have an energy density of more than 150 W-hr/lb and will utilize JP-10 and liquid oxygen as fuels. The goal of Phase I is to validate the proposed approach and complete an entirely specified and detailed system design that meets the goals set by ONR.
