Abstract:
PURPOSE: A manufacturing method of a metal-supported solid oxide fuel cell is provided to easily control thickness of each layer, to improve productivity, and to prevent excessive growth of Ni particles in a fuel electrode layer, by decreasing cell-manufacturing temperature. CONSTITUTION: A manufacturing method of a metal-supported solid oxide fuel cell, which comprises a metal support, a diffusion-preventing layer, a fuel electrode layer, a solid electrolyte layer, and an air electrode layer, comprises a step of laminating and attaching the diffusion-preventing layer, the fuel electrode layer, and the solid electrolyte layer in order, by using a green sheet which is manufactured through a warm isotactic press process by tape casting raw material powder composing at least one or more layers of the diffusion-preventing layer, a fuel electrode layer, a solid electrolyte layer, on one side of the metal support; and a step of sintering the laminate.
Abstract:
PURPOSE: A membrane-electrode assembly for slid oxide fuel cell is provided to improve performance of a solid oxide fuel cell by increasing the specific surface area of cathode powder. CONSTITUTION: A membrane-electrode assembly for slid oxide fuel cell comprises a cathode, an anode, and electrolyte membrane comprising solid oxide. The cathode comprises a specific surface area of 50 m^2/g or more, and perovskite type oxide comprising lanthanum(La) and strontium(Sr). The perovskite type oxide has a specific surface area of 60-150 m^2/g. The perovskite type oxide additionally comprises one or more elements selected from a group consisting of Co, Fe, Mn, Ni, Ti and combinations thereof.
