中文摘要：
根据对含水聚合物电解质膜（PEM）电化学反应器中各种界面电位变化范围的分析,可以推知各种此类电化学反应器中的固/水界面电位的变化范围.据此可根据各种材料的pH-电位图构筑pH-电位-稳定性图,用于分析这类反应器中各类材料的稳定性.介绍了构筑pH-电位-稳定性图的方法,并根据各种贵金属元素和阀金属元素的pH-电位-稳定性图,分析了它们在各类含水PEM电化学反应器中用作催化材料或结构材料时的稳定性.
英文摘要：
Based on the analysis of distribution of interfacial potentials at various solid/PEM and solid/water interfaces within the PEM-water electrochemical reactors and well-known pH-potential diagrams,the construction of pH-potential-stability diagrams is suggested as a combination of these two methods to provide a clear-cut view of the stability problems of various materials in environments within various PEM-water electrochemical reactors.The pH-potential-stability diagrams of the noble metal and valve metal elements were constructed and employed in the analysis of the stability of these elements as electrocatalysts or construction materials in various PEM-water electrochemical reactors.
