| Abstract: | The effect of electrolyte concentration and hydrogen pressure on hydrogen electrode process catalyzed by noble metal (Pt, Pd) have been studied. It is found that electrolyte concentration of 6-7mol/L is suitable for the electrode process and there is not limiting current involved in gas bulk diffusion process of hydrogen. The relation between hydrogen pressure and electrode potential conforms to Nernst equation. The different hydrogen pressure would be selected according to different demands of discharge current in Ni-H2 battery. |
