Title:
POLYMER ELECTROLYTE MEMBRANE, AND UTILIZATION OF THE SAME
Document Type and Number:
Japanese Patent JP2010102987
Kind Code:
A
Abstract:

To provide a polymer electrolyte membrane useful as material of solid polymer electrolyte fuel cell, that is, the polymer electrolyte membrane having low permeability of fuel and excellent durability while having sufficient proton conductivity as the solid polymer electrolyte fuel cell.

A composite electrolyte membrane includes at least a polymer electrolyte and a polymer non-electrolyte. The polymer electrolyte includes a structure with a sulfonic acid group introduced into a polymer of an aromatic vinyl compound structured not to have tertiary carbon when polymerized, or a copolymer mainly composed of an aromatic vinyl compound structured not to have tertiary carbon when polymerized.
