Electrolysis apparatus having anode catalyst for optimization of reverse water-gas shift reaction

摘要

The present invention relates to a high temperature electrolysis apparatus having an anode catalyst for maximizing a reverse water-gas reaction, which comprises an anode for performing a first reaction formula, H_2O + 2e- → H_2+ O^(-2) (steam electrolysis, favorable kinetics), a second reaction formula, CO_2+ 2e- → CO + O^(-2) (CO_2 electrolysis, slow kinetics), and a third reaction formula, CO_2+ H_2→ CO + H_2O (reverse water-gas shift, RWGS fast kinetics), and performs an electrolytic purification reaction through H_2O and CO_2 supplied to the anode, wherein an anode catalyst can be an LSCM.
