| Abstract: | With considering the fugacity of hydrogen,the activity of water and the partial pressure of water vapor in potassium hydroxide electrolyte,Nernst equation of metal hydride electrode reaction was calculated accurately on the basis of the relationship between electrochemistry and thermodynamics.Tri-electrode testing system was set up.Meanwhile,a kind of electrochemical testing method for pressure-composition isotherms was established,and details of the experiment were given.This electrochemical testing method for pressure-composition isotherms is capable of guiding the research on element-substitution and alloy-preparation of hydrogen storage electrode alloys,which involves many expe-riments. |
| Keywords: | Pressure-composition isotherms Electrochemical method Hydrogen storage electrode alloys |
