Abstract: Measurements of the mirage deflection in an electrochemical cell, where Cu electrodeposition and the ferro/ferricyanate reaction occurred, were performed in the dark under a potential step and in ac conditions with the aim of detecting thermal phenomena due to Joule and Peltier effects at the interface. A mathematical model based on the diffusion of thermal and ionic waves into the electrolyte allowed simulation of the mirage deflection in all cases. The experimental conditions under which the model is valid and the thermal effects can be separated from the ionic effects were discussed. Finally, the Peltier coefficient of the ferro/ferricyanate redox couple could also be measured using the ac technique.
