FIELD: electrolytic materials.
SUBSTANCE: invention relates to an electrolytic material for carrying out the transfer of positively charged hydrogen ions between the electrodes of a hydrogen fuel cell. A proton-exchange composite membrane SPES/HKUST-1 for solid polymer fuel cells with a thickness of 48-52 µm is proposed. The membrane contains an HKUST-1 organometallic frame structure doped with a sulfonated multiblock copolymer of polysulfone and polyphenylsulfone (SPES), in the following ratio, wt.%: HKUST-1 - 4.5-5.5, SPES - 94.5-95.5.
EFFECT: production of a proton-exchange membrane, which, due to its high ionic conductivity and exchange capacity, provides an increase in the efficiency of power generation by fuel cells, while significantly reducing carbon monoxide emissions, which has a positive effect on the environment.
