NOVELTY - Forming hydrogen fuel involves placing catalyst in reaction tank, adhering catalyst and fixing mixture of cobalt-boron powder and paper pulp foam on nickel sheet, where ratio of powder and foam is 2:0.5-1.5; adding reaction solvent, sodium borohydride solid powder and concentrated sodium hydroxide reagent, where amount of powder is 15-30% and ratio of powder, reagent and distilled water is 15:2-3:75-85, reacting at 55-65 degrees C; forming hydrogen and water vapor; conducting gas-liquid separation; purifying mixture and removing impurity, metal, non-metal ion salt and hydrogen of 99.99% purity.    USE - For the production of hydrogen fuel (claimed) used for fuel cell battery.    ADVANTAGE - The method provides high purity hydrogen, exhibits good safety performance, provides hydrogen with long life, and allows repeated use of catalyst. The method forms hydrogen with industrial scale purity of 99.99% and without hydrocarbon, sulfur, and carbon; uses sodium borohydride solution that avoids combustion in normal state environmental conditions, and does not cause pollution to the environment; exhibits improved safety and reliability of usage time; has fast reaction speed; and provides hydrogen with stable property, and long service life.    DETAILED DESCRIPTION - Production of hydrogen fuel involves placing catalyst in reaction tank, adhering the catalyst and fixing mixture of Co-B powder and paper pulp foam on nickel sheet, where ratio of Co-B powder and paper pulp foam is 2:0.5-1.5; adding reaction solvent to the reaction tank, adding sodium borohydride (NaBH4) solid powder, at the same time, adding concentrated sodium hydroxide (NaOH) reagent, where adding amount of NaBH4 solid powder in reaction tank is 15-30%, and the weight ratio of NaBH4, NaOH reagent and distilled water is NaBH4 solid powder:NaOH reagent:distilled water is 15:2-3:75-85, reacting under constant temperature condition of 55-65 degrees C, and forming hydrogen and water vapor in the reaction tank; conducting gas-liquid separation by passing mix gas of hydrogen and water vapor through heat exchanger, condensing water vapor into water in the reaction tank; and purifying mixture after gas-liquid separation for hydrogen purification, and removing impurity, metal, non-metal ion salt and hydrogen with industrial scale purity of 99.99%.    DESCRIPTION OF DRAWING(S) - The figure shows flow diagram illustrating method for production of hydrogen fuel.
