The preset invention relates to a solid oxide fuel cell stack capable of producing electricity, in which unit cell modules are connected in series and in parallel, and to a manufacturing method thereof. The solid oxide fuel cell stack is manufactured by: making a unit cell module comprising at least one unit cell formed on the outer surfaces of a flat tubular support, a first electrical interconnector formed on the front end of the support and at least a portion of the outer surfaces so as to be connected to a first electrode of the unit cell, and a second electrical interconnector formed on the rear end of the support and at least a portion of the outer surfaces so as to be connected to a second electrode of the unit cell; and stacking the unit cell modules such that the electrical interconnectors come into contact with each other.

Stack for a solid oxide fuel cell using a flat tubular structure

The invention relates to a stack for a solid oxide fuel cell and a manufacturing method thereof, and more specifically, to a stack for a high-capacity solid oxide fuel cell and a manufacturing method thereof, in which cell modules including a fiat-tubular reformer integrated with flat-tubular reactors are electrically connected to form a cell bundle.

Huge stack for flat-tubular solid oxide fuel cell and manufacturing method thereof

The present invention provides a large-scale solid oxide fuel cell stack and a method of manufacturing the stack. In the present invention, a segmented cell tube () is formed in such a way that unit cells connected to each other are formed on a cylindrical or flat tubular porous support (). A reformer tube () is configured such that reforming catalyst () is provided in a support (). The cell tube and the reformer tube are disposed at positions spaced apart from each other such that an air passage is formed on the outer surface of the reformer tube. A cell module () is formed by arranging the tubes such that a fuel gas flow passage is formed between the tubes. The solid oxide fuel cell stack is formed by integrating cell modules with each other.

Disclosed herein is an oxidation catalyst for use in removing fine soot particulates from exhaust gases of diesel engines, incinerators, boilers or other combustion devices, and to a method of removing fine soot particulates using the oxidation catalyst. The oxidation catalyst of the current invention functions to effectively remove fine soot particulates at a low temperature, and also, has thermal durability, and thus, the activity of the catalyst may be stably maintained even under thermal stress for a long time period. Further, the catalyst prevents poisoning due to a sulfur compound present in exhaust gases, and can maintain stable activity.

Disclosed is a method of coating a porous carrier layer of metal-metal oxide and depositing an active catalyst component on metal substrates, and a monolith module useful as a catalytic reactor with low pressure drop prepared using the metal substrate having the deposited catalyst. By forming the porous carrier particle layer on the metal substrate and depositing the catalyst particles thereon, the catalyst particles are drastically increased in deposition strength and impact durability. Also, the disclosed monolith catalyst module is used for a long time while the catalyst is not detached under high mechanical or thermal impact and high conversion efficiency thereof is maintained at a desired level, due to securely deposited catalyst particles.
