Abstract
Description
また、本発明は、前記複合コーティング層がコーティングされた固体酸化物燃料電池のHot-BOPを提供する。
一方、前記ニッケル層の被覆方法は特に限定されないが、一例として、電気蒸着法、無電解メッキ法などを使用することができる。
固体酸化物燃料電池のスタックの製造に使用されるSUS430に、以下の方法でコーティング層を形成した。
円筒形SUS(直径3/4インチ)を#320の軽い紙やすりを用いて研磨した。次に、前記円筒形SUSを1%濃度に希釈したフッ酸(HF)水溶液に4時間露出させて表面処理を進行させた。
次に、Niコーティング層を電気メッキ法により導入した。具体的には、1M硫酸ニッケル、0.2M塩化ニッケル水溶液にホウ酸を溶かして、pHを約4.0に調節した。これに、前記段階1で処理した円筒形SUSを陰極として入れて、50℃で円筒形SUSに5.4A/dm2の電流を加え、この時、正極はニッケルとしてニッケル電気メッキを進行させた。電気メッキ後、円筒形SUSを完全乾燥した。
次に、前記段階2で処理した円筒形SUSを1MのLa Nitrate水溶液に浸漬した後、電圧を印加した。具体的には、-1.1V、総蒸着電荷量4.0C、約20分の蒸着条件により蒸着を進行させ、表面に安定的なLa2O3酸化物がコーティングされたことを確認した。すべての蒸着過程は常温(23℃)、常圧(1atm)で行った。
前記実施例1においてNiコーティング層を導入することを除けば同様の方法でコーティング層を形成し、これを比較例1とした。
何ら処理していない円筒形SUSを比較例2とした。
前記製造した円筒形SUSを用いて、以下のようにクロム揮発程度を評価した。
前記実施例1で製造した円筒形SUSの複合コーティング層を以下のように観察した。
