Researchers at Ariel University in Israel have developed a new type of hydrogen generator for “on-demand” use with fuel cells. Hydrogen is produced in a catalytic hydrolysis reaction of sodium borohydride (NaBH4) with ruthenium powder as a catalyst. The proposed generator is portable and lightweight; has high energy density; is easy to use, refill, and clean; and is designed for long working periods with the capability for restart after prolonged rests.
