The generator will be based on ammonia borane hydrolysis. Ammonia borane has the capacity to release hydrogen when heated, and is primarily utilized as a chemical reducing agent. 

It offers more stability than water, and higher safety compared to sodium borohydride. 

AIST intends to develop a new catalyst to eliminate the use of precious metals. 

It will also work on developing a new electrode catalyst that would remain inactive during the hydrolysis of an aqueous ammonia borane and be active during negative electrode reactions.
