Ohmic heating, electrolyte solution

Ohmic heating of electrolyte solution as a consequence of electrolysis current is well known and has been utilised casually, e.g. for cooking food [25, 26]. Often, this side effect is undesirable and measures to avoid it are discussed, e.g. when batteries or electrochemical capacitors are charged/discharged [27, 28], and also in technical apphcation of electro-osmosis [29]. The phenomena connected with ohmic heating in traditional cells are investigated [30-32]. Also, it was well... 

This is the simplest model of an electrocatalyst system where the single energy dissipation is caused by the ohmic drop of the electrolyte, with no influence of the charge transfer in the electrochemical reaction. Thus, fast electrochemical reactions occur at current densities that are far from the limiting current density. The partial differential equation governing the potential distribution in the solution can be derived from the Laplace Equation 13.5. This equation also governs the conduction of heat in solids, steady-state diffusion, and electrostatic fields. The electric potential immediately adjacent to the electrocatalyst is modeled as a constant potential surface, and the current density is proportional to its gradient ...
