In this project, UltraCell proposes to dramatically increase our XX55 RMFC fuel cell durability, reliability, and performance under actual mission conditions. We will focus on four major areas.
? Increase the XX55?s operating life to greater than 2,000 hours and meet the durability requirements of a 2.29 meter drop plus standard military specification testing (810F/G, fuel cells.)
? Reduce weight from the system and fuel to achieve a target weight of roughly 10 pounds.
? Implement novel catalysts and system design in order for the fuel cell to provide power in 2-minutes.
? Achieve noise output of 5m non-aural detectability.
This proposed effort will spiral these new features into our existing XX55 RMFC fuel cell, and result in dramatic performance and reliability improvements over the current version. Once this goal is achieved, UltraCell will implement process improvements and manufacturing enhancements so that the fuel cells delivered under phase II of this project will be built off a standard production lot with full documentation. This will decrease unit cost and improve manufacturability and reliability. Final deliverables will be manufactured at our Dayton Ohio facility, under and industry standard quality plan.
As stated above, this effort will implement significant improvements to our XX55 fuel cell. The XX55 is a scalable and upgradeable technology. Initial versions delivered to the Air Force in early 2009 were fueled by a mixture of water and methanol and delivered 50W of power. We are currently adding water recovery to the XX55-WR to further increase its energy density, and the additional improvements in this proposal will be added to the XX55-WR. Future versions will be aimed at including higher energy density fuels such as JP8 and butanol resulting in energy density >1000Whr/Kg. The initial versions of the XX55 were tested by the Air Force and significantly improved during mid-2009 to include higher altitude operation and faster startup time along with improved reliability. All XX55 variants offer built in hybridization to allow the fuel cell to either recharge batteries, or maintain battery state of charge in a hybrid power system such as Air Force Battlefield Renewable Integrated Tactical Energy System (BRITES).
