Abstract
Lithiated nickel oxide (LixNiyO) electrodes have been successfully use d with molten K2S2O7/V2O5 at 400 degrees C and K2SO4/V2O5 at 480 and 5 20 degrees C in the electrochemical membrane removal of sulfur oxides from simulated flue gases,The porous gas-diffusion electrodes manufact ured in the laboratory from commercial Ni electrode material remained stable and conductive in this environment for periods up to 40 days. P olarizations are reported in these systems for current densities up to 50 mA/cm(2). The results show exchange current densities from 0.113 m A/cm(2) at 400 degrees C to 0.8 mA/cm(2) at 520 degrees C.
