摘要

PROBLEM TO BE SOLVED: To provide a permeable membrane that allows selectively to permeate hydrogen from a vapor of water or ethylene glycol, a fuel cell system and an electrolytic capacitor containing the permeable membrane. SOLUTION: The permeable membrane having a ratio between a hydrogen permeation speed and a water vapor permeation speed which is not less than a specific ratio is used.
