A fuel cell electrode catalyst includes: a noble-metal-supported catalyst including a carbon support and a noble metal supported on the carbon support; and a water-repellent material with which the noble-metal-supported catalyst is modified. The carbon support is mesoporous carbon in which a pore volume of pores having a pore size of 2 nm to 5 nm is 2.1 ml/g to 2.4 ml/g. An amount of the water-repellent material is 3% by weight to 7% by weight with respect to a total weight of the mesoporous carbon and the water-repellent material.

Fuel cell electrode catalyst

A manufacturing method of a tank including a tubular body portion, and dome-shaped side end portions formed on both sides of the body portion, the manufacturing method includes forming a tubular compact serving as at least part of the body portion from one fiber reinforced resin sheet by winding the fiber reinforced resin sheet including reinforced fibers impregnated with thermoplastic resin is wound several times around a peripheral surface of a core from a direction perpendicular to an axial center of the core in a state where the thermoplastic resin is melted.

Tank manufacturing method and tank

An excellent oxygen storage capacity is achieved even in the case used for a long period of time under high temperature conditions. An oxygen storage material contains a first particle made of a composite oxide of cerium and zirconium or a composite oxide of cerium, a rare-earth element other than cerium and zirconium, a second particle including a composite oxide of a rare-earth element, an alkaline-earth element and zirconium, and a precious metal. A part of the precious metal forms a solid solution with the composite oxide included in the second particle.

Oxygen storage material

An internal combustion engine in an engine exhaust passage of which an NOadsorption catalyst () adsorbing NOcontained in exhaust gas at the time of a low temperature and desorbing the adsorbed NOwhen the temperature rises and an NOstorage catalyst () are arranged. When the NOstorage catalyst () can store NO, the temperature of the NOadsorption catalyst () is made to forcibly rise to a target temperature at which the amount of NOwhich the NOstorage catalyst () can store is desorbed, and the NOdesorbed from the NOadsorption catalyst () is stored in the NOstorage catalyst ().

Exhaust purification device of internal combustion engine

The present invention provides an exhaust gas purification catalyst comprising a base material, and a two or more layered catalyst coating layer, formed on the base material, wherein the two or more layers have upper and lower layers, and wherein the upper layer contains a large amount of noble metal per liter of the base material more than that of the lower layer, and the lower layer contains a large amount of an oxygen storage/release material per liter of the base material more than that of the upper layer. This exhaust gas purification catalyst has more excellent HS purifying performance than conventional catalysts while maintaining purifying performance against NOx and the other exhaust gas components.

Catalyst for purifying exhaust gas

The present invention provides an exhaust gas purifying apparatuswhich can effectively purify an exhaust gas with the use of a plasma. The present exhaust gas purifying apparatuscomprises a NOpurifying catalystdisposed in an exhaust gas pipefor an internal combustion engine (ENG); a plasma generatorfor converting a gas into a plasma and supplying the plasma to the exhaust pipe at the upstream of the NOpurifying catalyst; a switching devicefor selectively supplying one of a recirculated exhaust gasand airas a gas to be converted into a plasma to the plasma generator; and an injectorfor adding a reducing agent to the gasto be converted into a plasma or a plasmaconverted from the gas by the plasma generator. The present invention further provides a method for controlling the exhaust gas purifying apparatus.

Exhaust gas purifying apparatus and method for controlling it

A catalyst for purifying exhaust gases includes a support including at le one composite selected from the group consisting of TiO.sub.2 --Al.sub.2 O.sub.3, ZrO.sub.2 --Al.sub.2 O.sub.3 and SiO.sub.2 --Al.sub.2 O.sub.3 composites, an NO.sub.x adsorbent including at least one member selected from the group consisting of alkali metals, alkaline-earth metals and rare-earth elements and loaded on the support, and a noble metal catalyst ingredient loaded on the support. The composites constituting the support improve initial NO.sub.x conversion of the catalyst, but also inhibit NO.sub.x purifying performance thereof from degrading even after a durability test.

Catalyst for purifying exhaust gases

A catalyst for purifying exhaust gases includes a porous support, an NO.sub.x storage component including at least one member selected from the group consisting of alkaline-earth metals, rare-earth elements and alkali metals, and loaded on the porous support, a noble metal catalyst ingredient loaded on the porous support, and disposed adjacent to the NO.sub.x storage component, and ceria (CeO.sub.2) disposed away from the noble metal catalyst ingredient. By disposing the noble metal catalyst ingredient adjacent to the NO.sub.x storage component, the reduction reactions of NO.sub.x can be facilitated in fuel-rich (i.e., oxygen-lean) atmospheres without being interfered by the ceria. By disposing the ceria away from the noble metal catalyst ingredient, oxygen, which has been stored thereon in fuel-lean (i.e., oxygen-rich) atmospheres, can be released from the ceria at a controlled rate in a controlled amount in fuel-rich (i.e., oxygen-lean) atmospheres, and thereby the released oxygen can be inhibited from reacting with HC and CO in fuel-rich (i.e., oxygen-lean) atmospheres. Thus, the catalyst is improved in terms of NO.sub.x purifying performance.

A method for purifying an exhaust gas containing an excess amount of oxygen, to remove nitrogen oxides, carbon monoxide and hydrocarbons therefrom, by bringing a catalyst into contact with the exhaust gas, the catalyst comprising a zeolite ion-exchanged with (a) cobalt or (b) both cobalt and at least one metal selected from the group consisting of alkaline earth metals and rare earth metals, the zeolite being selected from the group consisting of ferrierite, ZSM-5, ZSM-11, ZSM-12 and ZSM-20, and having a silica-to-alumina molar ratio of from 15 to 1,000.

Method of purifying oxygen-excess exhaust gas

A method for the catalytic purification of an oxygen-rich exhaust gas, wherein the catalyst comprises: a catalyst support, a zeolyte layer formed on the catalyst support and noble metals such as platinum, palladium and rhodium loaded on the catalyst. The catalyst for purifying the exhaust gas maintains a superior exhaust gas conversion performance over a long period of time.

Method for purifying exhaust gases

A catalyst for reducing nitrogen oxides from an exhaust gas containing the same in an oxygen rich atmosphere comprising (i) a zeolite having a molar ratio of SiO.sub.2 /Al.sub.2 O.sub.3 of at least 10, (ii) copper, and (iii) a rare earth ion, an alkaline earth metal and/or a valence variable metal.
