The nickel catalysts were prepared using waste coffee grounds(C) and de-fatty C(Cd), which has good activity in the hydrogen production of catalytic hydrolyzed NaBH4, its added value is greatly enhanced, and the hydrogen fuel cell can be used to generate electricity, suitable for 3C electronic products, this feasibility is present.The nickel catalysts were prepared using waste coffee grounds(C) and de-fatty C(Cd), and find out the best catalyst preparation procedure, so that the catalyst to catalytic hydrolysis NaBH4 hydrogen production has a very good activity. The results showed that the nickel catalyst (10% Ni/C and 10% Ni/Cd) had good activity on the hydrogen production of catalytic hydrolysis NaBH4, and the hydrogen production rate of the catalyst was 1569.1 ml/min•g at 30 ℃. Two hydrogen fuel cell in series (0.6 V) can drive the micro motor fan, this proves that 10% Ni/C and 10% Ni/Cd catalysts for portable hydrogen fuel cell power generation is feasible.The nickel catalysts were prepared using waste coffee grounds(C) and de-fatty C(Cd), which has good activity in the hydrogen production of catalytic hydrolyzed NaBH4, its added value is greatly enhanced, and the hydrogen fuel cell can be used to generate electricity, suitable for 3C electronic products, this feasibility is present. This result is in line with the circular economy and clean energy generation, is in line with the needs of the times.
