摘要: Waste heat recovery with thermo-electrochemical cells is limited by their low power and conversion efficiencies. Here we explore ionic liquid electrolytes mixed multiwall carbon nanotubes (MWCNTs) as alternative for cells. The results show that, upon addition of MWCNTs, the combination interfacial polarization ion pair dissociation reduces mass transfer resistances enhances at weight percentage MWCNTs up to 30%. This occurs in spite reduced open circuit voltage due percolated networks.
