The study of the electromotive forces of galvanic cells of various types is a fundamental part of the science of electrochemistry; but in addition, it is to a large extent a branch of the more general subject of thermodynamics. Indeed, little progress was made, until it was realized that many of the phenomena of electrochemistry are subject to the exact methods of thermodynamics. The application of these methods to the subject began with the studies of Helmholtz. The exact mathematical theory was first developed satisfactorily by Gibbs, who, however, was not concerned with the practical application of his results. Consequently, even after the importance of the contributions of Gibbs was realized, there remained the difficult task of devising methods of testing his conclusions and employing them in actual numerical calculations. This work has been carried out with great skill by G. N. Lewis in America, Brӧnsted and Bjerrum in Denmark, and many other workers in more recent years.
