API Engineering, a company with extensive undersea systems experience, will demonstrate an innovative power system that meets Navy energy density goals for future long duration Unmanned Underwater Vehicles (UUVs). Air-independent power sources are a major factor in UUV design and performance. Our revolutionary power system is built around API’s oxygen generator integrated with a solid oxide fuel cell (SOFC) and a hydrogen fuel source. Oxygen is produced by thermal decomposition of a safe non-combustible, non-volatile, room temperature chlorate solution. The hydrogen fuel is derived from a sodium borohydride solution. The room temperature liquid reactants enable easy refueling of the UUV with minimum shipboard handling equipment. We seek a commercial partner interested in the UUV market and interested in purchasing or licensing our technology.
