    摘要: A branched multiblock polybenzimidazole-benzamide copolymer, specifically, one consisting of a repeating unit represented by Formula 1, and a method for preparing the same; an electrolyte membrane using the branched multiblock copolymer, a consistent electrolyte paste/gel and a method for preparing the same; a membrane-electrode assembly (MEA) using the electrolyte membrane and the consistent electrolyte paste/gel and a method for preparing the same; and a fuel cell prepared from the membrane-electrode assembly. The electrolyte membrane according to the present invention has high hydrogen ion conductivity over a wide temperature range, and excellent physical properties such as mechanical properties, chemical resistance and thermal stability. Deterioration of the membrane properties is effectively controlled by phosphoric acid doping and high hydrogen ion conductivity is realized even with a low phosphoric acid doping level. This consistent electrolyte paste/gel may be useful in improving the operating performance of a fuel cell by coating the electrolyte uniformly.

    摘要: A novel approach based on the increase of the intrinsic oxidative stability of uncrosslinked membranes is addressed. The co-grafting of styrene with methacrylonitrile (MAN), which possesses a protected α-position and strong dipolar pendant nitrile group, onto 25 μm ETFE base film is disclosed. Styrene/MAN co-grafted membranes were compared to styrene based membrane in durability tests in single H2/O2 fuel cells. The incorporation of MAN improves the chemical stability dramatically. The membrane preparation based on the copolymerization of styrene and MAN shows encouraging results and offers the opportunity of tuning the MAN and crosslinker content to enhance the oxidative stability of the resulting fuel cell membranes.
