A study on hydrogen generation from NaBH4 solution using the high-performance Co-B catalyst
چکیده انگلیسی
For hydrogen generation from an aqueous alkaline NaBH4 solution, Co-B catalyst was prepared by the chemical reduction method using NaBH4 as a reduction chemical. To design a hydrogen generator, hydrogen generation rate was measured using the Co-B catalyst as a function of solution temperature, amount of catalyst loading, NaBH4 concentration, and NaOH (a base-stabilizer) concentration. Activation energy for the hydrogen generation reaction was measured to be 64.87 kJ mol−1. Compared to Ru catalysts previously used, the low-cost Co-B catalyst exhibited comparable activity for the hydrogen generation reaction. Using the hydrogen generation system employing the Co-B catalyst, a 2 W polymer electrolyte membrane fuel cell (PEMFC) stack was operated and successfully powered a cellular phone.
