Hydrogen Electrode Physical Chemistry. — although the standard hydrogen electrode is one of the most fundamental concepts of physical chemistry and its potential is defined as 0.000 v at any temperature as long as the activity of the hydrated proton and the fugacity of the hydrogen gas are unit, any temperature variation (and especially its increase) modifies the pressure of the water. — the choice that has been adopted is the standard hydrogen electrode, often abbreviated the s.h.e.
