Abstract: A polymer electrolyte membrane, a method for manufacturing the same, and a membrane electrode assembly containing the polymer electrolyte membrane are disclsosed. The polymer electrolyte membrane includes: a fluorine-based support containing a plurality of pores due to polymer microfibrillar structures; a hybrid porous support placed on one side or both surfaces of the fluorine-based support and comprising nanowebs obtained by integrating nanofibers into a nonwoven fabric containing a plurality of pores; and ion conductors with which the pores of the porous support are filled. The polymer electrolyte membrane can reduce hydrogen permeability while being excellent in both durability and ion conductivity.

Abstract: A catalyst, a preparation method therefor, an electrode containing the catalyst, a membrane-electrode assembly, and a fuel cell are disclosed. The catalyst contains a support; metal particles supported by the support; and a coating layer located on the metal particles, and includes any one selected from the group consisting of phthalocyanine, M-phthalocyanine (wherein M is a transition metal) and a mixture thereof. The catalyst has improved durability since a coating layer is formed on the surface of a commercial catalyst or a conventional catalyst through a relatively easy method without separate treatment. A carbon coating layer formed by post-treating a catalyst including the coating layer further improves durability. Material transfer ability and performance are also improved by a carbon nanofiber or a carbon nanotube generated during post-treatment.

Abstract: A hydrogenated petroleum resin, and a manufacturing method and use thereof, are provided. More specifically, a hydrogenated petroleum resin manufactured by subjecting dicyclopentadiene and an olefinic monomer to thermal polymerization and then carrying out a hydrogenation reaction, and a manufacturing method and use therefor are provided. The hydrogenated petroleum resin has the advantage of being useful in practical applications, since the petroleum resin is manufactured via thermal polymerization using inexpensive raw materials and on the contrary to conventional catalytic polymerization, a catalyst elimination process can be excluded. The hydrogenated petroleum resin produced in this way can be applied to, for example, an adhesive agent used in environmentally friendly sanitary goods, because the petroleum resin has excellent compatibility, adhesiveness and heat resistance, and has no bad odor.

Abstract: Disclosed is a hollow fiber membrane module. The hollow fiber membrane module includes a housing including a first fluid inlet, a first fluid outlet, a second fluid inlet and a second fluid outlet, and hollow fiber membrane bundles, each hollow fiber membrane bundle including a plurality of hollow fiber membranes, disposed within the housing so that a first fluid flows inside the hollow fiber membranes and a second fluid flows outside the hollow fiber membranes, and each hollow fiber membrane bundle further includes porous tubes having both ends closed and including a plurality of pores formed on the side surfaces thereof. The hollow fiber membrane module removes a region, into which a fluid flowing outside a hollow fiber membrane bundle has difficulty in permeating, thus allowing the fluid to uniformly flow. Therefore, even if hollow flow membranes are highly integrated, performance of the hollow fiber membrane module may be maximized.
