Title:
含リン原子フッ素化陽イオン交換膜,その製造方法およびそれを用いたプロトン伝導型燃料電池
Document Type and Number:
Japanese Patent JP3786838
Kind Code:
B2
Abstract:
A phosphorus atom-containing fluorinated cation exchange membrane substantially constituted with the following repeating units (A) and (B), and a proton conduction type fuel cell using the membrane as a solid polymeric electrolyte are provided. One embodiment for the membrane is useful as a perfluoro cationic exchange membrane for use in electrolysis of sodium chloride even under severe electrolytic conditions of higher concentration, higher temperature and higher electric density.(in which m is 0 or 1, n is 2 or 3, X, Y represents H or C6H4SO3H and the ratio for the number of repeating units is (A)/(B)=1.5 to 15).
