The results showed that electrochemical capacity of hydride measured by a conventional three-electrode open cell was higher than that determined in a sandwiched and in a sealed Ni/MH test cell.The electrochemical capacity of a hydride electrode measured in a sandwiched Ni/MH cell was very close to that measured in a sealed test cell. In order to optimize the metal hydride electrode alloy and elevalute the discharge capacity of an alloy, the factors affecting the discharge process of an actual hydride electrode were examined theoretically and experimentally. It can be concluded that the electrochemical capacity of a hydride electrode depends not only on the intrinsic properties of a hydrogen storage alloy, but also on the electrode preparation method and its working environment.
