The standard hydrogen electrode consists of a platinum electrode coated with platinum black.
The electrode is dipped in a solution of acid (usually 1M HCl) and pure H 2 gas is bubbled through
it at one atmospheric pressure (or 1 bar) and the concentration of H + is unity (1M). This electrode is
known as standard hydrogen electrode (S.H.E)

A Standard Hydrogen Electrode (SHE) is an electrode that scientists use for reference on all half-cell potential reactions. The value of the standard electrode potential is zero, which forms the basis one needs to calculate cell potentials using different electrodes or different concentrations...
With the help of these we can measure any concentration value of oxidation and reduction potential by kjeeping one concentration as unity .
