摘要： 法拉第定律描述电化学反应过程电子转移与物质转化之间的定量关系,是电荷守恒定律和物质守恒法则在电化学反应过程中的具体表现,构成现代电化学工程的科学基础之一.法拉第定律对早期的电化学理论发展起到重要推动作用,一直影响到现代电化学工业技术领域,包括电沉积行业,电池行业以及电化学分析技术等.通过回顾法拉第定律提出和发展的科学背景,分析其解决问题的思路,对于探究和解决现代电化学工程领域的课题有重要启示作用,对于理解电化学过程物质守恒,电荷守恒的"电中性"原则具有重要理论价值和科研指导意义.

Abstract: Faraday's Law describes the quantitative relationship between electronic transfer and matter transformation during electrochemical reaction, which constitutes one of the fundamental theories for the modern electrochemical engineering. Faraday's Law denotes an alternative formation of the charge and mass conservation in electrochemical reaction. Nowadays, it has been used in many advanced and mature industrial fields, including electro-deposition industry, battery manufacture, Coulomb analysis processes and so on. For better understanding Faraday's Law, this paper reviews the background of basic idea of Faraday's experiment and the following proof, since we believe that a historical review will discover some important factors in the past, which can highlight our future research in the electrochemical field.

Key words: Faraday's Law, electrochemistry, electrolysis
