Abstract: Described is a method of coating the inside of an exhaust gas purification catalyst filter with a predetermined amount of catalyst slurry while adjusting the distribution of catalyst components in or on a cell wall of the filter. A predetermined amount of catalyst slurry can be injected into an internal channel of a filter to solve conventional problems caused by excess or surplus slurry injection. The predetermined amount of slurry injected into the internal channel of the filter is coated on or in the cell wall, depending on the viscosity and particle size of the slurry. This enables a coating profile in which the slurry distribution at a front portion of the filter and the slurry distribution at a back portion of the filter differ from each other.

Abstract: Disclosed is an exhaust gas purification catalyst with a multilayered structure including an ultra-thin layer with a thickness of 20 micrometers or less and containing Rh, Pd, or both as at least one precious metal component, and to a method of manufacturing the same. The method includes a step of forming an ultra-thin layer having a thickness of 20 micrometers or less as the top layer of the catalyst by applying a polymer coating solution containing a polymer having a functional group capable of chelating with the precious metal component(s) on the surface of the multilayer structure of the catalyst. The disclosed catalyst exhibits improved removal efficiency for THC, CO, and NOx contained compared to an existing thin film-type catalyst. Since the disclosed catalyst is coated with a thin coating layer containing at least a portion of precious metal components, the disclosed catalyst exhibits improved performance while using the same amount of precious metal components as in conventional catalysts.

Abstract: A catalyst for fuel cells and a method of manufacturing the catalyst are disclosed. The catalyst forms shells in a dense structure so as to prevent elution of a transition metal and increases dispersibility through hydrophilization of the surface of the catalyst so as to be uniformly dispersed when an ink for forming a fuel cell electrode is manufactured. The catalyst may thus increase the performance and durability of a fuel cell.
