FIELD: physics.
SUBSTANCE: invention concerns the creation of DEB for the hydrogen-air and alcohol-air fuel cells (FC) with the use of polymeric proton-conducting electrolyte on the basis of polybenzimidazole film doped phosphoric acid and two gas-diffusion electrodes. According to the invention the polymeric proton-conducting electrolyte for manufacturing the membrane FC is made of the polymer "ПБИ-О-ФТ" doped with a strong acid, phosphoric or sulfuric.
EFFECT: creation of simple in assembling the diaphragm-electrode block for the fuel cell with high electrochemical characteristics.
