Sodium borohydride (NaBH4) is considered as the most potential hydrogen storage material for portable proton exchange membrane fuel cells (PEMFC) because of its high theoretical capacity. However, slow and poor kinetic stability generation from NaBH4 hydrolysis limits application. There are two main factors influencing kinetics NaBH4. One factor that alkaline by-products (NaBO2) reaction can increase pH solution, thus inhibiting process. It mainly happens in solution system. Another monotonous temperature leads to uncontrollable unpredictable rates solid This due excess heat generated this exothermic initial hydrolysis. In perspective, we summarize latest research progress emphasize design principles catalysts state The importance carbon catalyst support also highlighted.
