Abstract
This paper presents the IR-spectroscopy investigation of interaction between polymer protonconducting membranes (Nafion® brand) and various solvents. The solvent effect on the formed membrane structure is determined. The advantages of saturating membranes with methanol vapors over dipping into water/water-methanol mixture for membrane properties as a solid polymer electrolyte in the fuel cell are shown. An original method of feeding methanol vapors to a fuel cell by a hydrogen flow is proposed. Keywords: membrane, solid polymer el
