In electrochemistry, the concept of a reference electrode is fundamental. Introductory courses might mention the standard hydrogen electrode (SHE), its working principle, and its theoretical design; however, chances are that students will never have the opportunity to work with one. A hydrogen electrode should be a device readily available at the laboratory, either from an academic or an experimental point of view. The construction of a simple, robust hydrogen reference electrode, with materials available at the laboratory, is proposed. The main purpose is to fulfill the desired characteristics in a reference electrode such as stable potential over time, mechanical stability, and low cost. The designed robust hydrogen reference electrode (RHRE) presented adequate potential stability. Electrochemical characterization indicates that the RHRE is an acceptable system for electrochemical measurements. From an academic point of view, this electrode could be used as a practical tool for the learning process of the hydrogen electrode operation.

从理想到简单：坚固耐用且价格合理的氢参比电极

在电化学中，参比电极的概念至关重要。入门课程可能会提及标准氢电极（SHE），其工作原理及其理论设计；但是，有可能学生永远没有机会与一个人一起工作。从学术或实验的角度来看，氢电极都应该是实验室中易于使用的设备。提出了一种结构简单，坚固耐用的氢参比电极的结构，该材料在实验室中可用。主要目的是在参比电极中实现所需的特性，例如随时间推移的稳定电位，机械稳定性和低成本。设计的坚固的氢参比电极（RHRE）具有足够的电位稳定性。电化学表征表明，RHRE是用于电化学测量的可接受系统。从学术角度来看，该电极可用作氢气电极操作学习过程的实用工具。
