  • ANODE FOR ELECTROLYSIS AND METHOD OF PREPARING THE SAME
    Publication number: 20200208281
    Abstract: Provided is an anode for electrolysis having reduced overvoltage and improved lifetime while exhibiting high efficiency, and a method of preparing the same. Because the anode for electrolysis is prepared by electrostatic spray deposition, an active material can be uniformly distributed in a catalyst layer, and thus, an overvoltage can be reduced and lifetime can be improved while exhibiting high efficiency.
