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