Benzoxazine-based monomer, polymer thereof, electrode for fuel cell including the polymer, electrolyte membrane for fuel cell including the polymer, and fuel cell using the electrode
A benzoxazine-based monomer includes a halogen atom-containing functional group and a nitrogen-containing heterocyclic group. A polymer formed from the benzoxazine-based monomer may be used in an electrode for a fuel cell and electrolyte membrane for a fuel cell.
