Production of hydrogen from sodium borohydride in alkaline solution: development of catalyst with high performance

The hydrogen production from hydrolysis of sodium borohydride in alkaline solution has been extensively studied. As a result, we have studied that stylene-butadiene-rubber as a binder of catalyst electrode is very effective because their hydrophilic property promotes the infiltration of liquid fuel into the catalyst. The filamentary Ni mixed Co catalyst with superior performance of short initial waiting time and fast hydrolysis of sodium borohydride has been developed and showed a maximum hydrogen production rate of 96.3 ml/min g. Also because hydrogen gas can be generated at room temperature and has a high purity more than 99.99%, it can be directly used as a fuel to PEMFC.
