【 摘 要 】

The reactions of storage and release of hydrogen as a fuel of the fuel cell with sodium metaborate (NaBO2) / Sodium borohydride (NaBH4) media at various pressures and temperatures have been carried out. Hydrogen production is produced from hydrolysis of NaBH4 and hydrogen storage is carried out with NaBO2 media which is a by-product of the hydrolysis process of NaBH4. The process of hydrogen production by hydrolysis of NaBH4 takes place exotherm so that the highest speed occurs at low temperatures. Furthermore, the resulting NaBO2 is used as a hydrogen storage material at varying pressures and temperatures. The largest hydrogen storage capacity at 3 bar and 40°C is 35.23% by weight and increases after several repetitions of release and storage. An easy hydrogen storage and release system for fuel cells is needed to anticipate the use of fuel cells as an environmentally friendly energy source for housing and vehicles.
