Description
Summary:Characteristics of hydrogen evolution from non-stabilized and alkali-stabilized sodium borohydride solutions were systematically studied in order to understand the fuel storage features of borohydride in fuel cell applications. The effects of the sodium borohydride concentration, the temperature of the hydrolysis reaction, the sodium metaborate concentration, and the continuous temperature control for alkali-stabilized sodium borohydride solutions on the hydrogen generation and yield were investigated. Temperature variation was the major parameter that affected the stability of sodium borohydride solutions with and without stabilizing agents during hydrogen storage.
