Abstract: The present invention relates to an improvement in a process for the thermal fixation of a catalytically active component onto an alumina support and, more specifically, to an improvement in a process for the thermal fixation of a catalytically active component onto an alumina support for preparing a thermally stable catalyst for treating exhaust gas from an internal combustion engine, by means of thermally stable dispersion and fixation of the catalytically active component(s) for treating exhaust gas from an internal combustion engine, onto a surface or an internal space of the alumina support.

Abstract: Disclosed herein is a method of coating a catalyst support, in which a monolithic catalyst support provided therein with a plurality of longitudinally formed channels is quantitatively coated with catalyst slurry applied to post-treatment of exhaust gas, including the steps of: introducing catalyst slurry into a quantitative container whose bottom is vertically moved; moving a catalyst support to the top of a container such that the bottom of the catalyst support and top of the container are horizontally disposed each other; sealing the bottom of the catalyst support and the top of the container from the outside; moving the bottom of the container upward; and applying a vacuum to the channels of the catalyst support.

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.
