Abstract: Sodium borohydride contains hydrogen as high as 10.6%，and it is safe，no fire and explosion danger，and portable. This hydrogen supply system has the features of simple structure，fast starting，and adjustable hydrogen production speed. Therefore，sodium borohydride is a very promising hydrogen carrier and a perfect medium for pure hydrogen supply to proton exchange membrane fuel cell (PEMFC). In fact，the hydrolysis of sodium borohydride for hydrogen supply to PEMFC is in the way to real application. This review summarizes the recent advances in this hydrogen generation system including catalysts，reactors and purification methods，and the direction for sequent research is also discussed.
