The reference electrode plays an important role in the determination of the electrocatalytic activity of a given electrode material. The hydrogen reference electrode has several advantages, as it is stable, can be used in the whole range of pH values, and does not contaminate the system. However, its use is not widespread due to certain difficulties related to its construction and operation. In this context, we report the design of a reversible hydrogen electrode (RHE) characterized by its simplicity, reproducibility, portability, stability, and precision. Moreover, rigorous equations for the variation of the RHE potential on the solution concentration, temperature, and pressure were derived as well as for the conversion of a working electrode potential referred to RHE to the standard hydrogen electrode (SHE).

用于电催化研究的密室氢参比电极的设计和表征

参比电极在确定给定电极材料的电催化活性方面起着重要作用。氢参比电极具有几个优点，因为它稳定，可在整个 pH 值范围内使用，并且不会污染系统。然而，由于其建设和运营存在一定的困难，其应用并不广泛。在这种情况下，我们报告了一种可逆氢电极 (RHE) 的设计，其特点是简单、可重复性、便携性、稳定性和精确性。此外，还推导出了 RHE 电势随溶液浓度、温度和压力变化的严格方程，以及将工作电极电势（RHE）转换为标准氢电极（SHE）的方程。
