This work investigates coupling thermogalvanic redox processes with thermogalvanic corrosion. Ferri/ferrocyanide and iodide/triiodide redox couples were investigated at platinum and stainless steel electrodes. Dilute iodine displays a Seebeck coefficient of + 0.26 mV K- 1 at platinum electrodes and + 2.1 mV K- 1 at stainless steel electrodes. An apparent Seebeck coefficient of + 13.6 mV K- 1 could be achieved under optimal conditions. This is demonstrated to be due to a combination of the iodide/triiodide thermogalvanic redox couple and thermogalvanic iodine-induced corrosion of the stainless steel. © 2015 Elsevier B.V.
