PROTON CONDUCTOR COMPOSITION AND PROTON-CONDUCTIVE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a proton-conductive membrane capable of preventing short-circuiting of electrodes caused by penetration of the electrode through the proton-conductive membrane even if the membrane is thinned and obtaining satisfactory power-generating performance, and to provide a composition therefor.

SOLUTION: This proton conductor composition comprises a non-conductive filler and a polyarylene having a sulfonic group. This proton-conductive membrane is composed of the proton conductor composition, wherein the non-conductive filler content in the membrane is 3-50 vol.% and the particle diameter of the non-conductive filler is 3-90% of the thickness of the membrane.
