HYDROGEN GENERATION FOR HIGH ALTITUDE BALLOONS.
Abstract
A study and experimental program resulted in the design, fabrication and supply of a Hydrogen Generator (Development Model) and NaBH4 and NaAlH4 charges for use by the Army to fill high altitude balloons. A maximum of 270 SCF of 99% quality H2 can be produced within 30 minutes through the reaction of either six NaBH4 or six NaAlH4 charges with H2O. Each charge produces 45 SCF of H2. Primary emphasis of investigation was placed on NaBH4 and NaAlH4. The ease with which the NaAlH4 charge can be used in either generator and its anticipated low unit cost, $5.00/lb at production capacities of over 50,000 lb/yr, makes it more attractive than NaBH4. Hy drogen evolutions from NaBH4 are affected by water temperature, require a catalyst and a closed system to contain the foam and prevent the escape of H2 to the atmosphere. (Author)
