ABSTRACT: MiTi and its subcontractor are proposing an innovative integrated and low logistics footprint fueled hybrid solid oxide fuel cell (SOFC) and mesoscopic gas turbine engine generator (GTG) system with fuel-to-electricity efficiencies to 65%. The ultra-high speeds of the oil-free mesoscopic GTG with novel foil bearings and the high fuel-to-electricity conversion efficiency of SOFCs will result in a small, lightweight oil-free hybrid power system with increased system efficiency and power for longer duration missions, higher speeds and larger electrical loads. Taking advantage of existing aerospace and industrial fuel cell technology, and MiTi's mesoscopic turbomachinery experience, the proposed 9-month program will conduct design studies to balance the power demand between fuel cell and GTG to establish a hybrid configuration able to meet the specified mass, loiter and dash requirements. Overall subsystem performance predictions will be made and compared to existing fuel cell and turbogenerator subsystem data. The overall hybrid system configuration concept will be established and a detailed preliminary design for GTG subsystem including compressor and turbine impeller mean line analysis will be completed. Phase II hardware and testing plans will be prepared. BENEFIT: The hybrid SOFC/GTG power system is specifically intended for military application and in particular is intended for the family of SUASs used for intelligence, surveillance, and reconnaissance (ISR), target tracking and acquisition. Development of a wide variety of small, lightweight power systems will initially support military missions. Subsequent commercial applications include border patrol and search and rescue for emergency responders. The technology will also support portable remote power system needs that may have variable load demands.
