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.
