電化學分析儀 (Electrochemical Analyzer)
目的 Purpose
電化學分析儀主要用於研究材料之電化學特性與反應行為，可分析催化劑、電極材料及能源元件之氧化還原能力、反應效率、電荷傳輸特性與穩定性。常應用於燃料電池、二氧化碳還原、水分解、超級電容與電池材料等研究。
The electrochemical workstation is mainly used to investigate the electrochemical properties and reaction behaviors of materials. It can analyze the oxidation–reduction performance, catalytic activity, charge transfer characteristics, and stability of catalysts, electrode materials, and energy devices. This instrument is widely applied in research fields such as fuel cells, carbon dioxide reduction, water splitting, supercapacitors, and battery materials.
方法 Method
電化學分析儀透過控制電極電位或電流，量測材料在電解液中的電化學反應訊號。常用測試方法包含循環伏安法(Cyclic Voltammetry, CV)、線性掃描伏安法(Linear Sweep Voltammetry, LSV)、計時電流法(Chronoamperometry, CA)、計時電位法(Chronopotentiometry, CP)及電化學阻抗分析(Electrochemical Impedance Spectroscopy, EIS)等，可評估材料之催化活性、反應動力學、導電性、界面電荷傳輸能力與長時間穩定性。
The electrochemical workstation operates by controlling the potential or current applied to the electrodes and measuring the corresponding electrochemical responses in the electrolyte. Common electrochemical techniques include Cyclic Voltammetry (CV), Linear Sweep Voltammetry (LSV), Chronoamperometry (CA), Chronopotentiometry (CP), and Electrochemical Impedance Spectroscopy (EIS). These methods are widely used to evaluate catalytic activity, reaction kinetics, electrical conductivity, interfacial charge transfer behavior, and long-term stability of electrode materials and electrocatalysts.
