收集100-200 °C的低品位废热的需求备受关注。本文研究了三氟甲磺酸铁（Fe（CF 3SO 3）2/Fe（CF 3SO 3）3）氧化还原电对在100 °C以上的温度下在各种有机溶剂中的热电化学电池（TEC）的性能。在二甲基甲酰胺（DMF）中的TEC显示出1.51 mV K−1的最大塞贝克系数，并且在ΔT = 120 K（热侧145 °C）下使用DMF中的0.5 M三氟甲磺酸铁实现了660 mW m−1的最大功率密度。
The need to harvest low-grade waste heat at 100–200 °C has attracted much attention. In this paper, the performance of thermo-electrochemical cells (TECs) with an iron triflate (Fe(CF3SO3)2/Fe(CF3SO3)3) redox couple is investigated in various organic solvents at temperatures exceeding 100 °C. The TECs in dimethylformamide (DMF) showed the maximum Seebeck coefficient of 1.51 mV K−1, and the maximum power density of 660 mW m−1 was achieved using 0.5 M iron triflate in DMF at ΔT = 120 K (145 °C on the hot-side).
