综述了燃料电池多孔电极,气敏传感器以及多相腐蚀等不同领域在气/液/固三相线界面区特征对阴极过程的影响这一共性问题的各自研究特色与进展,分析了运用三相线界面区长度控制技术加速或减慢阴极反应速度的可行性,提出了借鉴和引进相关领域利用气/液/固三相线界面区特征来控制阴极反应的研究成果,从而发展气/液/金属复杂腐蚀体系测试方法、数据解析、模型化和行为预测等研究工作的新思路.

This paper summarizes the research progress in the field of effect of gas/liquid/solid three phase boundaries on the cathodic processes occurred in porous electrode of fuel cell, gas sensor and multi- phase corrosion. The discussion was made on the feasibility of improving performance of cathodic processes by controlling the length of three phase boundaries, and the suggestion was also proposed on possibility to apply the methods of controlling the length of three phase boundary for the studies of measuring, dataanalyzing, modeling and assessing the gas/liquid/metal muhiphase corrosion processes.
