ELECTROCHEMICAL CELL, ELECTROCHEMICAL STACK, AND METHOD FOR MANUFACTURING ELECTROCHEMICAL CELL
PROBLEM TO BE SOLVED: To suppress the worsening of a power generation capacity of an electrochemical cell by suppressing the diffusion of a transition metal element into an electrolyte layer.SOLUTION: An electrochemical cell comprises: an electrolyte layer including a solid oxide; and an air electrode and a fuel electrode which are opposed to each other through the electrolyte layer in a first direction. In the electrochemical cell, the solid oxide includes a lanthanum gallate-based perovskite oxide. The thickness of the fuel electrode is thicker than that of the electrolyte layer in the first direction. The electrolyte layer includes particles of which the average particle diameter is 2.0 to 8.0(μm).SELECTED DRAWING: Figure 3
【課題】電解質層への遷移金属元素の拡散が抑えられ、電気化学セルの発電能力が低下することを抑制する。【解決手段】電気化学セルは、固体酸化物を含む電解質層と、電解質層を挟んで第１の方向に互いに対向する空気極および燃料極と、を備える電気化学セルにおいて、固体酸化物は、ランタンガレート系ペロブスカイト型酸化物を含み、燃料極の第１の方向の厚さは、電解質層の第１の方向の厚さより厚く、電解質層を構成する粒子の平均粒径は、２．０（μｍ）以上、かつ、８．０（μｍ）以下である。【選択図】図３
