摘要： A binder for an electrode of a fuel cell is a basic polymer including a nitrogen-containing functional group and a proton conductive polymer having a phosphoric acid impregnation capacity of 200 wt % or less. An electrode for a fuel cell includes the binder and a catalyst, and a fuel cell includes the electrode. The electrode is manufactured by mixing the binder, a catalyst, and a solvent; and coating the mixture on a carbon support and heat-treating the coated mixture. The binder has excellent proton conductivity by having a phosphoric acid impregnation capacity of 200 wt % or less, and has improved durability without membrane damage and micro-structural changes due to swelling, which occurs when PBI is used as a binder. Accordingly, an electrode including the binder has improved phosphoric acid retention capacity, and increased wetting velocity. Thus, a fuel cell having improved efficiency can be manufactured due to the improved proton conductivity and durability of the electrode.

摘要： An electrolyte membrane includes a cross-linked reaction product of a benzoxazine monomer and a cross-linkable compound. The electrolyte membrane is impregnated with 300 to 600 parts by weight of phosphoric acid based on 100 parts by weight of the electrolyte membrane, and has a yield strain 0.5% or less, and a yield stress 0.3 Mpa or less. The cross-linked material has a strong acid trapping ability with respect to the benzoxazine compound and excellent mechanical properties due to a cross-linkage. Also, the solubility of the cross-linked material in polyphosphoric acid is low, thereby showing excellent chemical stability. Accordingly, when the cross-linked material is used, an electrolyte membrane having an excellent liquid supplementing ability and excellent mechanical and chemical stability at a high temperature can be obtained. The cross-linked material can be obtained by a simple polymerization process by combining a benzoxazine monomer and a crosslinkable compound and by using heat instead of using a polymerization initiator or a cross-linking agent.

摘要： A crosslinked object of a polybenzoxazine-based compound formed of a polymerized resultant of a first monofunctional benzoxazine-based monomer or a second multifunctional benzoxazine-based monomer with a crosslinkable compound, an electrolyte membrane including the crosslinked object, a method of preparing the electrolyte membrane, and a fuel cell employing the electrolyte membrane including the crosslinked object. The crosslinked object has a strong acid trapping capability with respect to the benzoxazine-based compound and high mechanical properties due to the crosslinking. The crosslinked object is very stable chemically because of elimination of solubility in polyphosphoric acid. The electrolyte membrane including the crosslinked object has excellent phosphoric acid supplementing capacity at a high temperature and mechanical and chemical stability. Specifically, even when an impregnated amount of a proton carrier, such as phosphoric acid, is increased to increase proton conductivity, the electrolyte membrane maintains excellent mechanical and chemical stability. Accordingly, the electrolyte membrane can be used in a fuel cell for high temperature and no humidity.
