Answer:

Its absolute electrode potential is estimated to be 4.44 ± 0.02 V at 25 °C, but to form a basis for comparison with all other electrode reactions, hydrogen's standard electrode potential (E0) is declared to be zero volts at any temperature. ... Hydrogen electrode is based on the redox half cell: 2 H+(aq) + 2 e− → H2(g)
