Electrolyte composition, solid electrolyte membrane, solid polymer fuel cell and manufacturing method for solid electrolyte membrane |
摘要 |
A method for manufacturing a solid electrolyte membrane made from an electrolyte composition that shows low methanol cross-over and exhibits high proton conductivity. The method includes applying an electrolyte composition including an organic solvent and a perfluorocyclobutane-containing polymer having a specific structure onto a substrate, and then removing the solvent. High proton conductivity is provided by sulfonic acid groups connected to the benzene rings. Reduction of methanol crossover is realized by introduction of a rigid structure with aromatic rings, or a combination of a rigid structure with aromatic rings and a three-dimensional cross-linked structure.
