NOVELTY - Hydrogen generator comprise stack (1), anode (2), cathode (3), membrane (4), anode separator (5), cathode separator (6), camera (7), and gas inlet (8).    USE - The generator is useful for modification of a PFSA membrane type (claimed).    ADVANTAGE - The generator is capable of producing hydrogen at a pressure greater than the pressure of the environment surrounding a membrane stacking and appropriate for work with no problems to these pressures.    DETAILED DESCRIPTION - Hydrogen generator comprises a stack (1) of at least one functional element, the stacking (1) comprises an anode (2) for the production of oxygen, a cathode (3) for hydrogen production and a membrane (4) located between the anode (2) and cathode (3), characterized in that the anode (2) communicates with an anode separator (5) and cathode (3) having a cathode separator (6), counting the anode separator (5) with a variable-volume encyclopedia and the cathode separator (6) with a variable-volume encyclopedia, and that the hydrogen generator further comprises a camera (7) sealed with a gas inlet (8) connected to a gas source, placing the stack (1) inside the chamber (7), and a processor configured to maintain a relationship between the free variable volume splitter cathode (6) and the free variable volume splitter anode (5) greater than or equal to 2:1. INDEPENDENT CLAIMS are:    (1) a method for the modification of a perfluorosulfunic acid (PFSA) membrane type comprising: (a) placing the membrane in a solution of a strong acid to 1-20%, (b) treating the membrane with ethanol at 96 degrees C, (c) permeating the membrane in a solution of zirconium oxychloride, (d) washing membrane with 10-60% phosphoric acid, (e) protonated membrane by bathing it in a solution of a strong acid to a 20%, and (f) drying of the membrane; and    (2) a membrane obtained by the method.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the hydrogen generator.
