The interest in thermogalvanic cells (TGCs) has grown because it is a candidate technology for harvesting electricity from natural and waste heat. However, the cost of TGCs has a major component due to the use of the platinum electrode. Here, we investigate new alternative electrode material based on conducting polymers, more especially poly(3,4-ethylenedioxythiophene)-tosylate (PEDOT-Tos) together with the ferro/ferricyanide redox electrolyte. The power generated by the PEDOT-Tos based TGCs increases with the conducting polymer thickness/multilayer and reaches values similar to the flat platinum electrode based TGCs. The physics and chemistry behind this exciting result as well as the identification of the limiting phenomena are investigated by various electrochemical techniques. Furthermore, a preliminary study is provided for the stability of the PEDOT-Tos based TGCs.

热原电池中的聚（3,4-乙撑二氧噻吩）-甲苯磺酸酯（PEDOT-Tos）电极

人们对热原电池（TGC）的兴趣不断增长，因为它是从自然和废热中收集电能的候选技术。然而，由于使用了铂电极，TGC的成本是主要的组成部分。在这里，我们研究基于导电聚合物，尤其是聚（3,4-乙撑二氧噻吩）-甲苯磺酸酯（PEDOT-Tos）和铁/铁氰化物氧化还原电解质的新型替代电极材料。基于PEDOT-Tos的TGC产生的功率随导电聚合物厚度/多层的增加而增加，并达到与基于扁平铂电极的TGC相似的值。通过各种电化学技术研究了这个令人兴奋的结果背后的物理和化学以及对极限现象的识别。此外，
