Standard hydrogen electrode - For all electrochemical measurements!

It has the characteristics of a quick response as a potential reference, high non-polarity, and minimal degradation over time.

In electrochemical measurements using devices such as potentiostats, an important factor is the reference electrode that serves as the basis for the potential. Typically, solid electrodes such as saturated calomel electrodes and silver/silver chloride electrodes are used. While these offer the convenience of being ready for use as soon as they are immersed in the test solution, they also present several issues, including degradation and changes over time with prolonged use, the time required for potential recovery when current accidentally flows, and contamination of the test solution by the internal liquid. Additionally, the use of hazardous substances like mercury is not environmentally friendly. Particularly in catalyst research related to fuel cells, these reference electrodes are supposed to be recommended as the standard for the "hydrogen electrode," but there have not been many options that are easy to use until now. Our TFCL-type standard hydrogen electrode has been developed with "ease of use" in mind.
