An energy-dense Al-NaBH4-PEMFC based power generators for unmanned undersea vehicles
Abstract
The main focus of the Phase II effort will be on long-term durability tests, optimization of the hydrolysis reactor, thermal balance of the system, and the integration of individual components of the system into a continuously operating power generation unit. The main activities willinclude:~ Hydrolysis reactor optimization and scale-up~ Improvements in the delivery of Al and NaBH4 reagents to the hydrolysis reactor~ Efficient thermal integration and heat management of the integrated H2 generator-PEMFCsystem~ Continuous and stable generation of the stream of humidified high-purity hydrogen for theoptimal PEMFC plant function~ Long-duration (several months) system stability and durability tests~ The integration of all components into a continuously operating power generation unit.The operational data collected will be analyzed to benchmark the performance of the power generation system and determine whether it could potentially meet the Navy UUV technical targets on energy density, endurance, start-up time and other criteria. The preliminary estimates of UUV energy section volume and energy density are: about 1500 L and 0.8-1.1 kWh/L, respectively (depending on onboard fuel storage options and assuming the mission duration of 70 days and energy output of 1800 kWh).
