FIELD: electricity.SUBSTANCE: present invention relates to material for making a proton-exchange membrane for an electrochemical device, particularly a fuel cell, an electrolysis cell or an accumulator. Activated boron contained in a matrix is boron nitride which is activated by a liquid containing radicals and/or ions of an acidic or alkaline solution for forming bonds in the boron nitride in the presence of an electric field, before use thereof to make said electrochemical device. The membrane is impermeable to hydrogen at pressure of 1 bar.EFFECT: proton-exchange membrane according to the present invention provides high mechanical and thermal stability and operates at a relatively high temperature and at room temperature.29 cl, 11 dwg, 4 ex, 2 tbl |
