Spontaneous penetration of hydrogen or oxygen through porous Teflon membranes into water or KOH solution was studied by a new method based on the measurement of the minimum gas overpressure necessary for the penetration at various temperatures. The results were compared with measurements on hydrogen-oxygen fuel cells and are in qualitative agreement with theoretical studies. The penetration of gases into the electrolyte can be prevented by their humidification before introducing them into the cells.
