Experiments using the CoCl2 catalyzed NaBH4/H2O hydrolysis were conducted at ambient and cold temperatures as well as under pressure. The purpose of these experiments was to (1) provide guidance in designing a portable reactor capable of producing 330 standard cubic feet (SCF) of hydrogen gas and (2) determine how to control the reaction so that it could be used to generate hydrogen gas to inflate lighter than air (LTA) vehicles.
