While conversion of low-grade waste heat into electricity is an important energy harvesting strategy, the thermo-electrochemical cells are one of the most promising devices for this application. This paper shows the study on thermo-electrochemical cell with polymer electrodes coated by oxidized multi-walled carbon nanotubes and the Fe(CN) 6 3- /Fe(CN) 6 4- based electrolyte. The developed cell demonstrates the current density values of more than 13 A/m 2 and a specific power of 140 mW/m 2 . Hypothetical Seebeck coefficient was found equal to 0.7 mV/K by the calculation based on the temperature dependencies of the open circuit voltage.
