Title:
SOLID POLYMER ELECTROLYTE, METHOD FOR PRODUCTION THEREOF, AND SOLID POLYMER FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2008/143362
Kind Code:
A1
Abstract:
Disclosed is a solid polymer electrolyte which has a water cluster structure formed by a hydrophilic group and occluded water in the solid polymer electrolyte, and which has a "water cluster structure difference" of 15.4 x 0.072 nm or less, wherein the "water cluster structure difference" is a difference between the diameter of a pore in the water cluster structure and the diameter of a bottleneck part in the water cluster structure both calculated by a dissipative particle dynamics method. The solid polymer electrolyte has improved ionic conductivity.
