The sodium borohydride dissolved in the liquid phase reaction is quick and the hydrogen storage capacity is low, unable to achieve stable hydrogen production, so the sodium borohydride in this study to form solid ingot for inhibition of the hydrolysis reaction of sodium hydroxide dissolved in aqueous solution by iodine titration analysis of water solution of sodium borohydride content and conversion the concentration of the reactive mole ratio to the yield of hydrogen, the dissolution is divided into two types: The first way is to control feed water pumps delivered to the sodium borohydride ingot is dissolved, and collect the export solution until dissolved. Second kinds of dissolution via polymer film into external liquid water to sodium borohydride by ingot dissolved concentration difference as the driving force of diffusion through the membrane and the external solution to the internal solution, until both sides reached a stable concentration. The electronic products in the fuel cell control system using discharge or release standby idle, without using water pump control, can achieve lightweight goals and improve the high cost disadvantage. The difference of water control in two sets of systems and the change of variables in order to study the stability of hydrogen production is the main research work.
