The central quantity in electrochemistry is the effective potential difference between a working electrode and the electrolytic solution. This potential, referred as the Galvani potential difference , cannot measured directly, but is determined relative to a second electrode acting as a reference with an unknown but constant Galvani potential difference. Computational models of electrochemical cells are subject to different restrictions than experiment and it should be possible to construct a single electrode electrochemical cell. The proposed project consists of designing such a computational single electrode cell using finite electrode field methods (see also project 1). This is a more theoretical project involving a number of fundamental issues. For this reason we will use classical force field models which will allow us to converge the calculations on the relevant spatial and time scales.
