Abstract: This application relates to a separator for a fuel cell and a fuel cell stack with improved durability, which contains the same, particularly to a solid oxide fuel cell stack. Specifically, this application allows an oxidizer and a fuel to flow in a counter-flow manner and a cross-flow manner in the fuel cell stack by forming an outlet manifold and an inlet manifold to have a specific shape, location and size in the separator. As a result, interlayer peeling, microcracking, etc. are prevented because no variation in temperature, reactant concentration, power, etc. occurs between each unit cell and the power density per unit volume is significantly improved because the volume is minimized.

Abstract: Provided is a method for manufacturing a sintered body for an electrolyte and an electrolyte for a fuel cell using the same. More particularly, the following disclosure relates to a method for preparing an electrolyte having a firm thin film layer by using a sintered body having controlled sintering characteristics, and application of the electrolyte to a solid oxide fuel cell. It is possible to control the sintering characteristics of a sintered body through a simple method, such as controlling the amounts of crude particles and nanoparticles. In addition, an electrode using the obtained sintered body having controlled sintering characteristics is effective for forming a firm thin film layer. Further, such an electrolyte having a firm thin film layer formed thereon inhibits combustion of fuel with oxygen when it is applied to a fuel cell, and thus shows significantly effective for improving the quality of a cell.

Abstract: Disclosed is an electrode catalyst for a hydrocarbon-fueled solid oxide fuel cell. The electrode catalyst includes ceria supports and iridium-nickel alloy nanoparticles dispersed on the surfaces of the ceria supports. The electrode catalyst can be inhibited from carbon deposition, a general phenomenon in conventional hydrocarbon-fueled solid oxide fuel cells. Therefore, the catalytic activity of the electrode catalyst can be maintained even at high temperature for a long period of time. In addition, the electrode catalyst contains a minimum amount of a platinum group metal for inhibiting the occurrence of carbon deposition and has a maximized surface area. Therefore, the electrode catalyst exhibits improved catalytic activity and can be produced at greatly reduced cost while suppressing the occurrence of carbon deposition.

Abstract: A metal/support catalyst for conversion of carbon dioxide to methane contains a metal including a transition metal and a support containing a perovskite-type oxide, on which the metal is supported. The metal/support catalyst for conversion of carbon dioxide to methane is capable of increasing the catalytic activity of the Sabatier reaction by promoting the formation of hydroxide ions and helping the production of formate, which is a reaction intermediate in the conversion of carbon dioxide to methane, without using a precious metal. In addition, it is capable of conducting the reaction stably for a long period of time.

Abstract: A metal-ceramic composite for a fuel cell anode is disclosed. In the metal-ceramic composite, the content of the metal is greatly reduced and the intervals between the metal particles are maintained constant, achieving improved activity and conductivity. The metal-ceramic composite includes a metal catalyst raw material and a mixed-conductive ceramic. The metal catalyst raw material is present in an amount such that the content of the metal catalyst nanoparticles in the metal-ceramic composite is significantly lower than in conventional metal-ceramic composites. The presence of a small amount of the metal catalyst nanoparticles in the metal-ceramic composite minimizes the occurrence of stress resulting from a change in the volume of the metal catalyst and provides a solution to the problem of defects, achieving improved life characteristics. Also disclosed is a method for preparing the metal-ceramic composite.
