Abstract
Official abstract text for this publication.
The solid oxide fuel cell includes a support of which a main component is a metal, an anode layer that is supported by the support, an electrolyte layer of solid oxide that is provided on the anode layer and has oxygen ion conductivity, a cathode layer that is provided on the electrolyte layer, and a porous layer of a metal that covers the cathode layer and a part of the electrolyte layer around the cathode.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A solid oxide fuel cell comprising: a support of which a main component is a metal; an anode layer that is supported by the support; an electrolyte layer of solid oxide that is provided on the anode layer and has oxygen ion conductivity; a cathode layer that is provided on the electrolyte layer; and a porous layer of a metal that covers the cathode layer and a part of the electrolyte layer around the cathode, wherein a thickness of the porous layer is 5 μm or more and 70 μm or less, and wherein the support, the anode layer and the electrolyte layer are integral sintered bodies made by sintering powder materials. 2 . The solid oxide fuel cell as claimed in claim 1 , wherein, in a cross section of the porous layer, voids of the porous layer occupies 20% or more of a total area of the voids and the metal. 3 . The solid oxide fuel cell as claimed in claim 1 wherein the metal of the porous layer includes silver. 4 . The solid oxide fuel cell as claimed in claim 1 , wherein the metal of the porous layer includes at least one of gold, platinum, palladium, or silver-palladium alloy. 5 . The solid oxide fuel cell as claimed in claim 1 , wherein a reaction resistance of the cathode layer is 0.27 Ω·cm 2 or less. 6 . The solid oxide fuel cell as claimed in claim 1 , wherein an ohmic resistance of the cathode layer is 0.25 Ω·cm 2 or less. 7 . The solid oxide fuel cell as claimed in claim 1 , wherein a porosity of the porous layer is 20% or more and 40% or less, and wherein the thickness of the porous layer is 5 μm or more and 20 μm or less.
