Electrolyte exhibiting a high positive Seebeck coefficient induced by semiclathrate hydrate formation for thermo-electrochemical conversion

In a mixture of water and TBAF (weight ratio of 0.4), the temperature dependence of the redox potential (Seebeck coefficient) of [Fe(CN) 6 ] 4−/3− reached a high positive value of +16 mV K −1 , owing to formation and dissociation of semiclathrate hydrate.
