Abstract
A process for the electrolysis of aqueous hydrochloric acid solution in an electrochemical flow reactor comprising a solid polymer electrolyte membrane, an anode, a cathode and backings, wherein the anode is comprised of an electrocatalytic material and an ionomer is disclosed. The process provides high current density at low cell voltage, and low HCl outlet concentration while minimizing side reactions.
