Abstract

A boundary element approach is formulated to solve the problem of deter- mining the potential and temperature distribution in electrochemical cells taking into account the effects of convection, migration and heat transfer. Two examples are analysed to assess the numerical formulation and satis- factory results are obtained. 1 Introduction It is always desirable to improve the energy conversion efficiency for the energy dissipated as heat can be regarded as loss of work. In electrochemical systems, the heat causes an increase or decrease of the cell temperature. Thus if the current density is increased in order to increase productivity without taking into account the accompany- ing changes in heat release, temperature rises at the
