Disclosed herein are several aspects processes of preparing a polymer electrolyte electrochemical cell in which supply of a reaction gas and discharge of an obtained gas can be smoothly conducted. This can be achieved by forming through apertures in a cathode or by forming a gradient of ion exchange

Disclosed herein are several aspects processes of preparing a polymer electrolyte electrochemical cell in which supply of a reaction gas and discharge of an obtained gas can be smoothly conducted. This can be achieved by forming through apertures in a cathode or by forming a gradient of ion exchange resin concentration of a catalyst particle cluster size.
