摘要

傳統商購二氧化鉛粉末自製水電解生成臭氧之膜電極組陽極材料，藉以探討其效能為本研究重點。商購的膜電極組，一旦運作過程中中斷電流將導致性能明顯衰退，而性能回復也因電流重新啟動而逐漸回復。本研究更投入二氧化鉛粉末自製，藉以發掘自製與商購粉末晶格結構差異與水電解效能的影響。將自製的二氧化鉛膜電極組應用在本實驗上。觀察自製與商購的MEA陽極材料在長時間與短時間電流中斷的環境下結構之變化。

In this study, home-made membrane electrode assemblies (MEAs) with commercial PbO2 powder were used to investigate their performance as anode in ozone generation via water electrolysis. We found that degrade phenomena happened for current interruption during operation period for commercial MEA and the recovery goes gradually along with current input once more. PbO2 powders were synthesized and their crystalline structures before and after current interruption were compared with those MEA made from commercial powders. Used home-made of lead dioxide film electrode group used in this experiment. Using SEM and XRD to observe the anode structure of home-made and commercial MEA when it operate at long time and short-time of interrupted current conditions.
