| Abstract： | In this paper, electroless-plated CoP catalyst supported on Ni foam was used for catalytic hydrolysis of sodium borohydride for hydrogen generation. Using a 2%NaBH4+5%NaOH solution, the hydrogen generation rate was as high as 917 mL·min-1·g-1 at 20℃. Kipp gas generator was employed for hydrogen generation. To stimulate the on/off operations of designed emergency power supply, the catalyst was artificially contacted or separated with reaction solution. Response time of the simulation system was only 2 min, meanwhile, good stability was proved through repeating 5 times. A novel emergency power supply based on the technology of sodium borohydride hydrolysis was introduced, which possessed unattended operation, auto start-stop, environmental friendly and reusable. |
