Abstrac
-An electrode reaction coupled with dismutation of the reduction product is treated mathematically for the case of a porous oxygen electrode in an alkaline medium. The electrode is regarded as a superposition of three continuous phases and the changes of the electrolyte concentration are neglected. The course of the theoretical current/voltage curve agrees satisfactorily with experiments for a porous nickel electrode containing silver as catalyst.

All forms of polarization losses are considered. It is not possible to obtain analytical solutions for the apparent current-density/overpotential and current-distribution relations under these conditions. Analytical solutions are, however, possible for some special cases, viz activation-ohmic and c
Based on the theory of the positive and negative plates of the lead-acid battery, a system of six partial differential equations and one integral equation was derived describing the behaviour of the complete cell. The theoretical discharge behaviour of the plates either separately or in a cell was c
