The hydrogen electrode is based on the redox half cell corresponding to the reduction of two hydrated protons, 2H (aq), into one gaseous hydrogen molecule, H2(g). General equation for a reduction reaction: $${\displaystyle {\underset {\text{ox}}{\text{(oxidant)}}}+z{\ce {e- <=>}}\ {\underset … Zobraziť viac In electrochemistry, the standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials. Its absolute electrode potential is … Zobraziť viac During the early development of electrochemistry, researchers used the normal hydrogen electrode as their standard for zero potential. This was convenient because it could actually be constructed by "[immersing] a platinum electrode into a … Zobraziť viac Because of the high adsorption activity of the platinized platinum electrode, it's very important to protect electrode surface and solution from the … Zobraziť viac The scheme of the standard hydrogen electrode: 1. platinized platinum electrode 2. hydrogen gas Zobraziť viac The choice of platinum for the hydrogen electrode is due to several factors: • inertness of platinum (it does not corrode) • the capability of platinum to catalyze the reaction of proton reduction • a high intrinsic exchange current density for proton reduction … Zobraziť viac The standard redox potential of the deuterium couple is slightly different from that of the proton couple (ca. −0.0044 V vs SHE).

WebA small decrease (V H2 = 110 mL min −1) barely limits the polarization curve but is already visible in the current density distribution in Figure 4c. At V H2 = 65 mL min −1 (equivalent to a stoichiometric flow factor of λ ≅ 1) the polarization curve breaks in after 300 mA/cm 2 , indicating considerable mass transport overpotential.
