Abstract: Disclosed herein are a solid oxide fuel cell and a method for manufacturing the same. The solid oxide fuel cell includes an anode layer; a cathode layer; an electrolyte layer interposed between the anode layer and the cathode layer; wherein the anode layer includes an Si-based compound selected from a group consisting of SiC, Si3N4, and a mixture thereof. The present invention performs a role of the chain at the boundary of the anode layer and the electrolyte layer by applying the Si-based compound to the anode layer to improve the wettability of metal particles and suppressing the grain growth, thereby making it possible to improve the long-term reliability of the fuel cell.

Abstract: Disclosed is a metal oxide-yttria stabilized zirconia composite, including 25˜75 wt % of a metal oxide-3 mol % yttria stabilized zirconia composite, and 75˜25 wt % of a metal oxide-8 mol % yttria stabilized zirconia composite. A solid oxide fuel cell is also provided, which includes the metal oxide-yttria stabilized zirconia composite as an anode layer or a support layer of an anode layer.

Abstract: Disclosed herein is a solid oxide fuel cell, including: one or more unit cells, each being provided with a ceramic tubular support; a metal layer which is formed on an outer circumference of one end of each of the unit cells and collects a first electric current; a metal foam which is formed in each of the unit cells and collects a second electric current; and a manifold which is connected with one end of each of the unit cells to receive the first current collected in the metal layer and which is connected with the other end of each of the unit cells to receive the second current collected in the metal foam. The solid oxide fuel cell is advantageous in that since the metal foam and metal tube are employed, an additional current collector is not required, and the electric current generated from an internal electrode can be easily collected through a manifold by connecting the metal foam and metal tube with the manifold.

Abstract: Disclosed is a solid oxide fuel cell, including a polygonal tubular support an outer surface of which has a plurality of planes, a plurality of unit cells respectively formed on the plurality of planes of the tubular support, inner connectors for connecting the plurality of unit cells in series, and a pair of outer connectors for connecting the plurality of unit cells connected in series to a current collector, so that respective unit cells are connected in series on the planes of the tubular support, thus exhibiting excellent cell performance and high power density per unit volume, and maintaining high voltage upon collection of current to thereby reduce power loss due to electrical resistance. A method of manufacturing the solid oxide fuel cell is also provided.
