摘要： An embodiment method for preparing a polymer electrolyte membrane includes preparing a nanostructure including an imidazole group, mixing a benzimidazole-based polymer, the nanostructure, and a crosslinking agent including an isocyanate group to prepare a mixture, and forming the mixture in a form of a film. An embodiment fuel cell includes a polymer electrolyte membrane including a reaction product of a benzimidazole-based polymer, a nanostructure including an imidazole group, and a crosslinking agent including an isocyanate group, a cathode on a first surface of the polymer electrolyte membrane, and an anode on a second surface of the polymer electrolyte membrane opposite the first surface.

摘要： Disclosed is a polyamide composite resin composition that reduces an evaporative gas and an oligomer that can be generated from a fuel tube for a vehicle. The polyamide composite resin composition may include an amount of about 45 to 70% by weight of a polyamide resin; an amount of about 10 to 30% by weight of a nylon component; an amount of about 15 to 30% by weight of a thermoplastic elastomer; an amount of about 3 to 10% by weight of a clay component; and an amount of about 0.3 to 2.5% by weight of a carbon nanotube (CNT), all the % by weight based on the total weight of the polyamide composite resin composition.
