    摘要： Provided are a dendrimer solid acid and a polymer electrolyte membrane using the same. The polymer electrolyte membrane includes a macromolecule of a dendrimer solid acid having ionically conductive terminal groups at the surface thereof and a minimum amount of ionically conductive terminal groups required for ionic conduction, thus suppressing swelling and allowing a uniform distribution of the dendrimer solid acid, thereby improving ionic conductivity. Since the number of ionically conductive terminal groups in the polymer electrolyte membrane is minimized and the polymer matrix in which swelling is suppressed is used, methanol crossover and difficulties of outflow due to a large volume may be reduced, and a macromolecule of the dendrimer solid acid having the ionically conductive terminal groups on the surface thereof is uniformly distributed. Accordingly, ionic conductivity is high and thus, the polymer electrolyte membrane shows good ionic conductivity even in non-humidified conditions.

    摘要： An oligomer solid acid and a polymer electrolyte membrane using the same. The polymer electrolyte membrane includes a macromolecule of oligomer solid acid having an ionically conductive terminal group at its terminal end and the minimum amount of ionically conductive terminal groups required for ion conduction, thus suppressing swelling and allowing a uniform distribution of the oligomer solid acid, thereby improving ionic conductivity. Since the number of ionically conductive terminal groups in the polymer electrolyte membrane is minimized and the polymer matrix in which swelling is suppressed is used, methanol crossover and difficulties of outflow due to a large volume are minimized, and a macromolecule of the oligomer solid acid having the ionically conductive terminal groups on the surface thereof is uniformly distributed. Accordingly, ionic conductivity is high and thus, the polymer electrolyte membrane shows good ionic conductivity even in low humidity conditions.

    摘要： An ion-conducting, sulfonated and crosslinked copolymer for use in a fuel cell is disclosed. The ion-conducting, sulfonated and crosslinked copolymer is made up of four monomers. The first monomer is an aromatic diol. The second monomer includes two groups, each group capable of reacting with the hydroxy groups of the first monomer, and each group independently selected from a nitro group and a halogen group. The third monomer is one of the first monomer or the second monomer, except that one of the hydrogen atoms attached to a benzene ring is substituted with —SO3Y, where Y is selected from hydrogen (H), lithium (Li), sodium (Na), potassium (K) and trialkyl ammonium of the form HNR3 where R is an alkyl group having from 1 to 5 carbon atoms. The fourth monomer includes at least three groups, each independently selected from a hydroxy group, a nitro group, and a halogen group.
