Abstract: An electrochemical process was conducted to store hydrogen in CNTs (carbon nanotubes), where the CNTs were used as the cathode of Ni-MH cells. In this experiment, the CNTs and Ni-nanopowder were taken as sample cathode with KOH solution as electrolyte. With 50 charge-discharge cycles tested for the Ni-MH cells to measure their charge/discharge capacity and power, the hydrogen storage property of CNTs was determined on an Arbin BF-2043 series battery testing system to control the testing procedure. The experimental results showed that when the charging current into a gram of CNTs was 120 mA, the discharge capacity would be 126.386 mA·h·g with a stable discharging process available to provide a utilization rate up to 97%. It is evident that CNTs is indeed a kind of challenging material for hydrogen storage, and the experiment can provide an experimental reference for preparing hydrogen storage cells made from CNTs.
