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 that includes: a fuel electrode, an air electrode, and electrolyte disposed between the fuel electrode and the air electrode; a separator for separating a fuel gas flowing through the fuel electrode and air flowing through the air electrode; and a sealing portion constituted of a glass composition for bonding the separator and the electrolyte, wherein the sealing portion includes a first region and a second region, the first region is exposed to the fuel gas and the air, the first region does not contain Ba, and the first region includes a surface of the sealing portion, the second region is sandwiched between two first regions, the first region of the two first regions that is exposed to the air is sandwiched between the separator and the electrolyte, and the second region is a remaining region of the sealing portion excluding the two first regions and the second region contains Ba. 2. The fuel cell according to claim 1 , wherein the electrolyte includes a proton conductor. 3. The fuel cell according to claim 2 , 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 Gd. 4. The fuel cell according to claim 3 , wherein M is Yb.
