Continuously operating thermo-electrochemical cells (thermocells) are of interest for harvesting low-grade waste thermal energy because of their potentially low cost compared with conventional thermoelectrics. Pt-free thermocells devised here provide an output power of 12 W m for an interelectrode temperature difference (ΔT) of 81 °C, which is sixfold higher power than previously reported for planar thermocells operating at ambient pressure.
连续运行的热电器件(thermocells)因其成本可能低于传统热电材料而受到关注,可用于回收低品位废热。本文设计的无 Pt 热电器件在 81°C 的电极间温差(ΔT)下提供 12 W m 的输出功率,比以前在环境压力下运行的平面热电器件报告的功率高 6 倍。
