Аннотация: The effect of preliminary high-power ultrasonic treatment of Nafion® alcohol solutions on the properties of membranes and characteristics of membrane-electrode assemblies of membrane-based fuel cells has been explored. The changes in the microstructure of Nafion® membranes upon ultrasonic treatment of their solutions lead to an increase in their proton conductivity, gas permeability and the membrane-based fuel cells power by almost 10%.

Ключевые слова: proton exchange membrane fuel cell, perfluorinated sulfonic acid membrane, functional polymer, ultrasonication, fuel cell performance, proton conductivity, Nafion®.
