Abstract
Official abstract text for this publication.
The present specification relates to a solid oxide fuel cell and a cell module including the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrolyte support-type solid oxide fuel cell comprising: a fuel electrode; an electrolyte support; and an air electrode provided in a consecutive order, wherein the electrolyte support includes a gadolinium-doped ceria-based electrolyte layer and a yttria-stabilized zirconia-based electrolyte layer each provided on both surfaces of the gadolinium-doped ceria-based electrolyte layer, wherein the yttria-stabilized zirconia-based electrolyte layers each have a thickness of 5 μm or more and 20 μm or less, wherein the gadolinium-doped ceria-based electrolyte layer has a thickness of 500 μm or more and 1000 μm or less, and wherein a thickness ratio of the gadolinium-doped ceria-based electrolyte layer: the one yttria-stabilized zirconia-based electrolyte layer is 1: 0.001 or more and 1: 0.1 or less. 2. The electrolyte support-type solid oxide fuel cell of claim 1 , wherein the gadolinium-doped ceria-based electrolyte layer includes (Gd 2 O 3 ) x (CeO 2 ) 1-x (x=0.02 to 0.4). 3. The electrolyte support-type solid oxide fuel cell of claim 1 , wherein the yttria-stabilized zirconia-based electrolyte layers each include (Y 2 O 3 ) x (ZrO 2 ) 1-x (x=0.05 to 0.15). 4. A cell module comprising the solid oxide fuel cell of claim 1 as a unit cell.
