摘要

本論文發展水電解製超氧技術中之超氧發生器期以解決日益嚴重之醫療器具之流放物汙染問題。PEM水電解製超氧技術乃根據燃料電池的逆反應技術。整體裝置主要由鈦金屬基材之電解板、陰陽極端板、雙極板、及防漏墊圈等零件，搭配膜電極組(MEA)，組合而成的超氧發生器。水電解過程中須提供直流電壓和純水，在低電壓高密度電流的狀態下，利用膜電極組質子傳輸功能使純水進行電解作用。水電解過程中，陽極生成高純度、高濃度的超氧/氧，陰極處產生出氫氣。在超氧發生器組裝測試中探討各種不同參數，如電解板含各種不同貴金屬成分對PEM水電解超氧發生器的性能影響、水流量壓力、電壓強度等對超氧濃度變化探討，以分析PEM水電解之超氧發生器製超氧的效率與電解生命週期。本研究經單元超氧發生器開發研究探討過後延伸出多單元超氧發生器電解堆。

Purpose of this study is to develop ozone generator with proton exchange membrane (PEM) water electrolyzer technology in order to resolve the increasingly serious pollution of effluent from medical equipments. PEM water electrolyzer technology is the reverse operation of proton exchange membrane (PEM) fuel cell. Constitutes of ozone generator include the titanium base electrolytic plate, stainless steel end plate, bipolar plate, gasket, as well as membrane electrode assembly (MEA). With the input of DC power supply and DI water, the water electrolyzer starts to operate with MEA under high current density and middle voltage. During the operation, high concentration ozone/oxygen and hydrogen are generated in anode and cathode, respectively. Effects of noble metal coating on Ti-based electrolytic plate and then ozone generation capability as well as life cycle are evaluated with the change of inlet water flow rate and input voltage. Results concluded form ozone generator with one unit (or MEA) are utilized to construct ozone generator with two units successfully.
