摘　　要：讨论了电解质浓度和氢气压力对低载量贵金属(Pt、Pd)催化氢电极过程的影响.实验结果表明:适宜的电解质浓度为6～7mol/L;氢的气相扩散不存在极限电流;氢气压力与电位的关系符合能斯特方程;当氢镍电池选用不同的放电电流时,可相应地选用不同的氢压.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.
