摘　　要：针对一种碱性固体电解质的离子传导行为进行了研究,并测试了其对K+等离子的渗透作用。实验表明,该碱性膜工作时是依靠K+的迁移来保证反应的连续进行,是一种应用于碱性环境的阳离子交换膜,且该碱性膜具有微孔结构,对离子半径小于膜孔径的离子有渗透现象。该碱性膜适用于碱性电解水制氢/氧技术,且其应用价值值得进一步研究。The present work aims at studying ionic conduction of alkaline solid electrolyte.The infiltration of K+etc.of the membrane was investigated.The experiments showed that the membrane with micropores,which depended on the conduction of K+to make the continuous reaction,was a kind of cation exchange membrane applying in alkalescence circumstance.The infiltration would occur when the radius of ion was smaller than that of micropore.This alkaline membrane is benefit for the generate of hydrogen and oxygen by alkaline water electrolysis and the value of its application deserves further study.
