  Electrochemistry - Wikipedia, the free encyclopedia
Electrochemistry is a branch of chemistry and studies the reactions that can take place at the interface of an electronic conductor (the electrode, which can be a metal or a semiconductor including graphite) and an ionic conductor (the electrolyte).
Like in many physical chemistry topics, electrochemistry uses tables, the most used (in electrochemical cells) is the standard reduction potentials table, which is determined in a modified version of galvanic cell using an Hydrogen electrode as cathode, because Hydrogen is taken as reference, standard reduction potential for that substance is zero (gray highlight).
In the 1960s–1970s quantum electrochemistry was developed by Revaz Dogonadze and his pupils.

 Quantum electrochemistry - Wikipedia, the free encyclopedia
Generally speaking, the field is comprised of the notions arising in electrodynamics, quantum mechanics, and electrochemistry, and so is studied by a very large array of different professional researchers.
This being the case, electrochemistry, which is particulary concerned with the electronic states of some particular system, is already, by its nature, tied into the quantum mechanical model of the electron in quantum chemistry.
Dogonadze is a particularly celebrated promoter of quantum electrochemistry, and is also credited with forming an international summer school of quantum electrochemistry centered in Yugoslavia.

That argument went back and forth but finally when quantum theory was developed, it became absolutely clear that space, if you look at in a microscopic scale, is more like the base of a waterfall with a lot of frothy, seething activity going on, rather than just something like a placid, empty space.

A particular problem arises by the proton transfer in fuel cells, which requires accurately captures of the quantum mechanical characteristics of light-atom motion in simulations of large-scale systems.
Classical mechanics as used in molecular dynamics simulations does not describe quantum mechanical effects, such as zero-point energy constraints and tunneling, which are often very significant in these processes.
We will develop computational tools that treat the quantum dynamics of light-atom motion reliably within large-scale simulations of molecular materials, in a way that can be folded into multi-scale modeling of kinetics.

Chemical physics refers to a branch of physical chemistry in which the emphasis is on the interpretation and analysis of the physical properties of individual molecules and bulk systems, instead of their reactions.
Theoretical chemistry is another major branch, in which the emphasis is on the calculation of the properties of molecules and systems, and which uses the techniques of quantum mechanics and statistical thermodynamics.
For the present purpose it is convenient to regard physical chemistry as dealing with three aspects of matter: its equilibrium properties, the structure of molecules and bulk matter, and matter's ability to change.
