Hydrogen energy is easy to use by converting into electric energy and has a high efficiency. In addition, the hydrogen has attracted a great attention as next generation energy because water is emitted only after used. Recently, chemical hydrides were used to produce hydrogen for fuel cells. In this study, sodium borohydride (NaBH₄) was selected and sodium hydrogen carbonate (NaHCO₃) was used as a catalyst. The amount of hydrogen increased with increasing the temperature and the activation energy to initiate the reaction was 0.233kJ/mol·K. The product gas was analyzed by gas chromatography so that 99.9512 % of hydrogen, 0.0471 % of carbon dioxide (CO₂) and 0.0017 % of carbon monoxide (CO) were measured, respectively. The byproduct after the hydrolysis reaction was analyzed by XRD but the NaHCO₃ was not detected. The GC and XRD results suggest that NaHCO₃ was decomposed into CO and CO₂ during the reaction although NaHCO₃ was used as catalyst. Finally, a hydrogen generation system was developed which has a pressure regulating reactor to control the hydrogen flow rate.
