Abstract
【解決手段】低温領域でのSOECの酸素発生反応(OER)活性の低下を回避するため、酸素極用の電極触媒として表面にCeOXとの界面を形成したPt粒子をGDC粒子と混合したものを使用する。
【選択図】図4
Description
ここで、前記混合導電体はGDCであってよい。
本発明の他の側面によれば、白金粒子とCeOX粒子とからなる粉末に水中で電位の掃引を行うことにより前記白金粒子の表面に前記CeOX粒子との界面を形成する、請求項1または2に記載の電極触媒の製造方法が与えられる。
ここで、前記白金粒子とCeOX粒子とからなる粉末は、前記CeOX粒子を塩化白金酸溶液に分散して乾燥し、その後水素還元を行うことによって得られる粉末であってよい。
また、前記CeOX粒子は沈殿法により調整してよい。
また、電気水中で行う電位の掃引は、電極上に前記白金粒子とCeOXとからなる粉末を搭載し、前記電極を硫酸水溶液に浸漬した状態で複数回電位の掃引をおこなってよい。
本発明の更に他の側面によれば、前記何れかの電極触媒を使用した固体酸化物形水蒸気電解セルが与えられる。
一方、SOECデバイスを作成する目的で、1500℃で焼結したGDCペレット(相対密度:95%以上)上にスラリー状にした電極(水素極:NiO(キシダ化学工業製)−GDC粉末、酸素極:Pt−CeOX−GDC粉末、Pt−GDC粉末(3/1))をそれぞれ塗布し、焼き付け処理(水素極作成:1250℃、1h、酸素極作成:1100℃、1h)を行った。このようにして作製した酸素極の断面のSEM像を図2に示す。図2において、下側1/4ほどを占める比較的一様な比較的濃色の部分がGDCからなる電解質領域であり、それより上にある多孔質の比較的淡色の部分がPt−CeOX−GDCからなる酸素極領域である。
O2− → 1/2O2+2e−
によって酸素ガスが発生することで酸素ガスが発生する様子を図4に模式的に示す。
