Ariel researchers develop new type of hydrogen generator with sodium borohydride for on-demand use

Green Car Congress

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 (NaBH 4 ) with ruthenium powder as a catalyst. Zakhvatkin et al. 1c00367.
