Description
燃料電池10の構成について、図面を参照しながら説明する。燃料電池10は、いわゆる固体酸化物型燃料電池(SOFC:Solid Oxide Fuel Cell)である。燃料電池10は、縦縞型、横縞型、燃料極支持型、電解質平板型、或いは円筒型などの形態を取りうる。
空気極50の微構造について、図面を参照しながら説明する。図2は、空気極50の断面を模式的に示す図である。
次に、燃料電池10の製造方法の一例について説明する。
また、空気極50を焼成した後、降温中も酸素濃度の高い焼成雰囲気を維持することが好ましい。具体的には、純酸素雰囲気又は酸素濃度が40%以上の酸素リッチ空気雰囲気で空気極50の焼成体を常温まで降温させることによって、第1表面50Sにおける第1の比R1の露出面51Sにおける第2の比R2に対する比を微調整することができる。

以下のようにして、サンプルNo.1〜No.10に係る燃料電池を作製した。
各サンプル10個ずつについて、空気極の外表面を顕微鏡及び目視で観察することによって、外表面におけるクラックの有無を確認した。確認結果を表1に示す。
まず、X線光電子分光分析(Physical Electronics Inc.社製、型式ESCA−5700ci、X線源:MgKα(400W、1254.6eV)、分析径:800μmφ、X線と試料との角度:45°、X線と分光器との角度:54.7°)によって空気極の最表面上の任意の5箇所におけるLa濃度とSr濃度を検出し、La濃度に対するSr濃度の第1の比R1(5箇所における比の算術平均値)を算出した。
サンプルNo.1〜No.10について、燃料極側に窒素ガス、空気極側に空気を供給しながら750℃まで昇温し、750℃に達した時点で燃料極に水素ガスを供給しながら還元処理を3時間行った。
