1. A method of manufacturing a proton exchange membrane with a surface fiber structure, the method comprising:
inserting the membrane into a vacuum chamber having a magnetron sputtering system with a cerium oxide target, the sputtering system having an atmosphere of inert gas and O2 as a reactive gas;
igniting plasma as an ionized atmosphere to provide simultaneous plasma etching of a surface of the membrane and deposition of cerium oxide with a layer thickness in a range of tenths to tens of nanometers on the etched surface of the membrane resulting in formation of fibers; and
magnetron sputtering a layer of catalyst onto the surface of the membrane, wherein the catalyst comprises iridium.
