Description
まず、直径1インチ(2.54cm)の多孔質ステンレス鋼基板上にイットリア安定化ジルコニア(YSZ)APS電解質(厚さ65μm)を堆積した。電解質の透過率(空気中測定)は7.3×10−10cm2Pa−1sec−1であった。1モル濃度の硝酸ガドリニウムと硝酸セリウムの前駆体水溶液を調製し、硝酸塩分解後の最終組成物としてGd0.20Ce0.80酸化物(20GDC)を生成するのに適切な比率で配合した。8YSZのAPSコーティング上に硝酸塩溶液を約3.5mg/cm2の量で塗布し、真空下室温、次いで空気中70℃でそれぞれ約5分間乾燥し、このサンプルを水酸化テトラメチルアンモニウム(TMAH)が入ったメスフラスコに接続された封止ガラス管に入れた。TMAHが沸騰するまで加熱し、塩基の蒸気を80℃に加熱した浸透基板上に流し、硝酸塩が酸化物へ化学転化するのを促進した。20分後、サンプルを取り出した。浸透から化学変化までの操作を5回繰り返した。電解質をX線回折(XRD)したところ、微結晶サイズ(ブロードな反射ピークによって示された)の20GDC酸化物が認められ、硝酸塩の20GDCへの低温分解が起きたことが確認された。続いて、サンプルを500℃に上げ、室温に戻す熱サイクルにさらし、固体酸化物型燃料電池が作動中に暴露される高温環境の模擬実験を行った。浸透物の高密度化後のガス透過率(空気中測定)は1.3×10−10cm2Pa−1sec−1であった。追加の浸透と化学転化を行い、透過率をさらに低減した。
