The characteristics of rapid gaseous H-2 charging/electrochemical discharging of the metal hydride negative electrode were investigated for the application in Fuel Cell/Battery (FCB) systems. They were evaluated with the H-2 gas absorption, followed by the subsequent electrochemical discharging in the electrolyte solution (6M KOH). Then, the cyclability of charge-discharge was also examined. it was observed that more than 70% of the theoretical capacity was charged within 10 min with 0.3 MPa and 0.5 MPa of the initial H-2 pressures. The electrochemical discharge curve showed that more than 86% of the absorbed H-2 was discharged. Furthermore, the cycled charge-discharge process indicated that the H-2 gas charge and electrochemical discharge process is an effective way to rapidly charge and activate the metal hydride without degeneration.
