Abstract

Provided is an electrolysis system in which current efficiency of an electrolytic hydrogenation reaction is improved by restricting the amount of water migrating to a cathode while also supplying moisture to an electrolyte membrane and reducing resistance of the electrolyte membrane. Provided is an electrolysis system including an electrolyte membrane having proton conductivity, a cathode containing a catalyst for an electrochemical reaction involving protons, an anode containing a catalyst for oxidizing water to produce protons, and a structure that supplies water vapor to the anode, wherein the anode catalyst layer contains, in part thereof, an ionomer having proton conductivity, and a ratio of (002) diffraction peak intensity of carbon relative to (110) diffraction intensity of Ir oxide of the anode catalyst layer and ohmic resistance of the electrolysis system are within specific ranges.
