Description: Thermal gradient effects on mass transport-controlled system have been investigated. Results have been analyzed under accurate experimental conditions to determine the thermal gradient. They show that this gradient leads to a limiting diffusion current dependence as it was written by Marchiano and Arvia. Electrochim. Acta 13, 1657 (1968), 14, 741 (1968).

By this way, those functions are shown to be efficient.
