Poly(3,4-ethylenedioxythiophene)-tosylate (PEDOT-Tos) electrodes in thermogalvanic cells

The interest in thermogalvanic cells (TGCs) has grown because it is a candidate technology for harvesting electricity from natural and waste heat. The polymer electrode PEDOT is investigated as potential material to replace Pt electrode in TGCs. The power of the TGC increases with thickness and PEDOT provides an efficient electron transfer to Fe(CN)₆³⁻.
