Description
本発明は、固体酸化物セル(SOC)、特に固体酸化物燃料電池(SOFC)又は固体酸化物電解槽セル(SOEC)における電極材料としての使用に適した複合材料に関する。SOFC又はSOECは固体酸化物電解質及び2つの電極からできており、当該電極のうち少なくとも1つは前記複合材料を含む。
固体酸化物セルとして、一般には、種々の用途のために設計されたセル、例えば、固体酸化物燃料電池又は固体酸化物電解槽セルが挙げられる。これらのタイプのセルは当該技術分野で公知である。典型的には、固体酸化物セルは2つの電極層に挟まれた電解質層を含む。動作の間、約400℃〜約1100℃の温度が用いられる。一方の電極は空気と接触しており、他方の電極は燃料ガスと接触している。
本発明は、SOCにおける電極材料として適した複合材料に関する。複合材料は、少なくとも2つの非混和性の混合イオン電子伝導体(MIEC)からなる。
本発明は、固体酸化物セルにおける電極材料としての使用に適した複合材料であって、少なくとも2つの非混和性の混合イオン電子伝導体(MIEC)からなる複合材料に関する。本発明において、MIECは、SOFC電極動作条件下で10−3S/cm以上の比イオン伝導率及び10−2S/cm以上の比電子伝導率の両方を有する材料を意味する。
実施例1
本発明による「(Gd 0.6 Sr 0.4 ) 0.99 Fe 0.8 Co 0.2 O 3−δ 」ペロブスカイトの調製
組成(Gd0.6Sr0.4)0.99Fe0.8Co0.2O3−δを有する鉄コバルト系ペロブスカイトの粉末を、L.A.Chick、L.R.Pederson、G.D.Maupin、J.L.Bates、L.E.Thomas、G.J.ExarhosによってMaterials Letters、10 6(1990)に開示されているグリシン硝酸塩燃焼経路を用いて調製した。
錐体の製造のために、10mmの直径を有するシリンダを、適切なダイを用いて単軸方向に押した。シリンダを60〜65トンの圧力で平衡に押した。その後シリンダを1250℃/12時間で焼結した後、ダイヤモンド工具を用いることにより機械加工して錐体にした。焼結後のシリンダの密度をアルキメデスの方法によって決定した。シリンダの密度はXRDから測定した値の90%を超えた。
(式中、Rsは高周波での実軸との切片であり、σ*は、電解質の比伝導率である)を用いて決定した。円錐形電極の微細構造を、JEOL JSM−840走査型電子顕微鏡(SEM)を用いて調べた。
