Electrochemistry Guides and Free Tools
Plain answers to the questions researchers ask before they choose equipment.
- Reference Electrode Potential Converter
Free tool: convert a potential to RHE, SHE or another reference electrode.
- Ag/AgCl vs SCE vs Hg/HgO: Which Reference Electrode Should You Use?
Compare Ag/AgCl, saturated calomel, Hg/HgO, Hg/Hg₂SO₄ and Ag/Ag⁺ reference electrodes: potentials, which electrolyte each suits, and common mistakes.
- PEM vs AEM Electrolyzers: What Is the Difference?
How PEM and AEM water electrolyzers differ: the ion carried, the electrolyte, catalysts, materials and maturity, with a comparison table.
- H-Cell vs Gas Diffusion Flow Cell for CO₂ Reduction
When to use an H-cell, a gas diffusion flow cell or a zero-gap electrolyzer for CO₂ electroreduction, with a comparison of what each is good for.
- How to Set Up a Three-Electrode Electrochemical Cell
Step-by-step three-electrode cell setup: what the working, reference and counter electrodes do, how to place them, and the mistakes that spoil a measurement.
