Abstract
Official abstract text for this publication.
The fuel cell of the present disclosure includes: a unit cell including: a fuel electrode, an air electrode and electrolyte disposed between the fuel electrode and the air electrodes; a separator for separating a fuel gas flowing though the fuel electrode and air flowing through the air electrode; and a sealing constituted of a glass composition for bonding the separator and the electrolyte, and at least a surface region of the sealing portion exposed to the fuel gas and the air does not contain Ba.
First claim
Opening claim text (preview).
What is claimed is: 1 . A fuel cell comprising a unit cell including: a fuel electrode, an air electrode and electrolyte disposed between the fuel electrode and the air electrodes; a separator for separating a fuel gas flowing though the fuel electrode and air flowing through the air electrode; and a sealing constituted of a glass composition for bonding the separator and the electrolyte, and at least a surface region of the sealing portion exposed to the fuel gas and the air does not contain Ba. 2 . The fuel cell according to claim 1 , wherein the sealing portion contains Ba in a second region that is a remaining region excluding the first region. 3 . The fuel cell according to claim 1 , wherein the electrolyte includes a proton conductor. 4 . The fuel cell according to claim 3 , wherein the proton conductor is represented by a compositional formula: BaZr 1-x M x O 3 , where 0.05≤x≤0.5; M is at least one selected from the group consisting of Sc, In, Lu, Yb, Tm, Er, Y, Ho, Dy, and/or Gd. 5 . The fuel cell according to claim 4 , wherein the proton conductor is represented by a compositional formula: BaZr 1-x M x O 3 , wherein M is Yb.
