電化學系統內部會牽涉離子遷移行為而電荷會轉移至液、固相間產生化學反應。但是電化學反應過程所施加的能量常消耗在與電化學本身反應非直接相關的因素上,因此可望透過程序強化技術提升電化學系統性能、降低系統能耗,達到縮小反應設備所需體積、降低整體成本以及提升設備安全性。
本實驗室首次開發能在離心力場下進行水分解反應的 E-Higee 電解系統,透過調整電解液濃度、液體體積流率、電解盤轉速甚至是電解電壓都被認為是可以增加電解效率的操作因素。
以計時電壓法、計時安培法和交流阻抗法等電化學技術,觀察到 E-Higee 電解系統可以大幅度地降低靜態電解系統內部能耗,並從陰極電壓減少量、省能程度、電流效率、溶液電阻以及電荷傳遞電阻等電解效率參考指標的變化趨勢,凸顯出 E-Higee 電解系統其高電解效率及低系統電阻的優勢。
本先導性開發研究目的在於藉由程序強化技術概念應用於新穎電解系統的建立,並以實驗數據驗證此 E-Higee 電解系統的可能性,提供電解反應器其它新選擇。
Electrochemistry is concerned with the transfer of charge, by the movement of ions, in a liquid or solid phase through which electrochemical reaction of species can be achieved. But the process of electrochemical reaction always consumed lots of energy on indirect reactions. Improvements in performance of electrochemical technology are targeted at reduced energy consumption, or higher power output, increased reaction rates through process intensification technology which result in smaller reactors, lower cost and higher safety.
Currently, we are developing a E-Higee system which is capable of conducting water electrolysis under a centrifugal field. The electrolyte concentration, electrolyte flow rate, rotational speed, and even controlled bias were taken into consideration as the operating variables to pursue better efficiency of electrolysis in the E-Higee system.
According to the experimental results, we observed some interesting phenomena of reduced energy consumption with E-Higee system by controlled-potential, controlled-current and AC impedance methods. Data collected from cathode potential reduction, power saving, current efficiency and the change of resistance revealed noticeably higher efficiency of electrolysis and lower resistance in E-Higee system, compared to stationary system.
The aim of this preliminary study is to investigate the energy saving of water electrolysis with process intensification technology, and built up a high efficiency of electrolysis equipment.
