SBIR-STTR Award

Leveraging fielded experience with award winning fuel cell products, Jadoo proposes a fuel flexible approach operating on a common fuel cell platform. Jadoo will develop a life cycle model supported by empirical data obtained from our fielded products, specific application data, and fuel technology specific characteristics. This model will be used to assess multiple energy storage technologies against dismounted soldier (DS) and unattended ground sensor (UGS) application requirements. The Jadoo fuel cell system architecture is well proven over hundreds of commercially fielded systems showing high reliability (>7000 hours), low cost (100W system under $1000), instant startup (less than 2 seconds), start/stop resilience (>7000 start/stops), and a wide environmental temperature (-20 to 55°C). Jadoo has already developed standardized fuel canisters that use ammonia borane, metal hydrides and sodium borohydride using a common fuel cell interface. Jadoo’s N-Stor interface enables a single fuel cell system to operate on any one of the above mentioned technologies without the need to change the system design. Jadoo has already demonstrated the operation of its commercial N-Gen fuel cell system on the above mentioned fuels as well as with reformed methanol and sodium silicide technologies. The needs and requirements of markets must drive the choice of fuel technology. Similarly, applications like cell phones require a rechargeable lithium ion battery while flashlights typically use primary batteries. Utilizing this universal fuel cell approach, end customers may use any combination of fuel storage technologies based on cost, storage capabilities, performance characteristics, refill requirements, and field availability.

Jadoo Power Systems, Inc., (Jadoo) proposes further development of two chemical hydride fuel sources that have demonstrated promise to meet the needs of both Dismounted Soldier (DS) and Unmanned Ground Sensor (UGS) applications. During the phase I fuel study, it was determined that both Ammonia Borane and Siloxene were both fuels that promise to meet the requirements of DS and UGS on a range of stated objectives, including Cost, Energy Density, Startup Time, Reliability, Usability, and Operating Environments. Jadoo will develop and/or refine two fuel cartridge architectures to account for two promising hydrogen production chemistries, pyrolysis and hydrolysis. Jadoo will continue to improve its current ammonia borane development with the exploration of composite pellet designs. The main goal of the development being the elimination of harmful contaminants, which will increase the reliability and energy density of the system. Additionally, Jadoo will develop a hydrolysis canister architecture that will enable to usage of siloxene, a low cost, solid state fuel that generate hydrogen through water hydrolysis. These architectures will be developed to utilize Jadoo’s interface technology without the interdependence of water recirculation from the power system.
