Abstract
An electrolyte membrane can include a porous support and an oligomeric ionomer with which the support is impregnated, and a method of manufacturing the same. The electrolyte membrane can include a support including a reaction product of a benzimidazole-based polymer and a crosslinking agent, and an oligomeric ionomer with which the support is impregnated and containing a proton conductive group.
Claims20
An electrolyte membrane, comprising:
- a support comprising a reaction product of a benzimidazole-based polymer and a crosslinking agent;
- and
- an oligomeric ionomer formed in the support, the oligomeric ionomer comprising a proton conductive group.
A fuel cell, comprising:
- an electrolyte membrane including a support and an oligomeric ionomer, wherein the support comprises a reaction product of a benzimidazole-based polymer and a crosslinking agent, and wherein the oligomeric ionomer is formed in the support and the oligomeric ionomer comprises a proton conductive group;
- an anode disposed on a first side of the electrolyte membrane;
- and
- a cathode disposed on a second side of the electrolyte membrane, wherein the first side is opposite the second side.
A method of manufacturing an electrolyte membrane, comprising:
- preparing a crosslinked product by reacting a benzimidazole-based polymer, a nanostructure comprising an imidazole group, and a crosslinking agent;
- obtaining a support in which the nanostructure is removed from the crosslinked product by adding a monomer comprising a sulfonic acid group and the crosslinked product to a solvent;
- and
- obtaining the electrolyte membrane in which the support is impregnated with an oligomeric ionomer polymerized from the monomer by reacting the monomer.
