Description
燃料電池の電極に配合されたニッケル触媒成分は、燃料電池に組み込まれた初期には、酸化物として存在する。上記ニッケルの触媒機能を発現させて、燃料電池から電力を取り出すには、電極中のニッケル酸化物をニッケル金属に還元する必要がある。このため、燃料電池の電解質−電極積層体を加熱するとともに水素を作用させることにより、初期還元工程が行われる。この初期還元工程におけるニッケル酸化物の還元が十分に行われない場合、燃料電池の性能が低下することから、ニッケル酸化物の還元程度が高いほど、燃料電池の性能が向上すると考えられる。
本実施形態では、X線吸収微細構造解析(X−ray Absorption Fine Structure:以下、「XAFS」という。)を利用し、燃料電池中の電極の還元雰囲気等を再現した装置によってニッケル酸化物の還元率を求める。なお、還元率は、添加した触媒のニッケル金属成分の質量に対して、還元されたニッケル金属の質量%で示される値である。
以下、本実施形態における還元率の測定手順について説明する。本実施形態では、試料を400℃に加熱するとともに、H2ガスを10%含むHeガスの雰囲気下で測定を行う。ニッケル酸化物(NiO)を上記条件下で還元する過程における上記XANSのK吸収端スペクトルの変化の一例を図1に示す。
本願発明は、燃料電池の電極用触媒材料であって、ニッケル酸化物とコバルト酸化物とを含んで構成されるとともに、ニッケル金属成分とコバルト金属成分の合計質量に対して、コバルト金属成分を2〜15質量%含むものである。
以下、実施形態の詳細を説明する。
図3に示すように、所定量のNiO粉末に、Co(NO3)2・6H2Oと、Fe(NO3 )3・9H2Oとをそれぞれ所定量秤量して、Co成分とFe成分を配合した触媒材料を調整する。なお、試料名称の末尾の2桁の数字は、Ni金属成分とCo金属成分の合計質量に対するCo金属成分の質量%、及びNi金属成分とFe金属成分の合計質量に対するFe金属成分の質量%を示している。
上記各試料は、図4に示すように、ニッケル酸化物粒子の表面に、コバルト酸化物粒子又は鉄酸化物粒子が分散担持された形態を備えている。
上記操作によって得られた触媒材料にバインダとしてECヒビクル(日進化成株式会社ECヒビクル 試作3−097)を添加して1軸圧縮成形し、直径10mm厚み1mmの圧粉成形体を得た。
本実施形態に係る測定装置3は、燃料電池の初期還元工程を再現するため、図5に示すように、水素ガスを上記各試料2に作用させながらヒータ6によって加熱し、還元率を測定する。このため、水素ガスを流動させることができる容器1内に、上記試料2を設置し、この容器ごとXAFS測定装置3aの検出器4,5間に設置して測定を行った。
図6に示すように、還元率は、試料2を窒素雰囲気下、所定時間をかけて400℃まで昇温させ、400℃の温度下において、水素3%を含むヘリウムガスを流動させ、上述した手法によって、90秒ごとに測定を行った。測定は、ニッケル酸化物(NiO標準試料)と、上記各試料について行い、上述した手法によって各試料におけるNiの還元率を求めた。また、添加したコバルト酸化物及び鉄酸化物についても還元率を求め、これら還元率から触媒金属の全質量に対するトータル還元率も求めた。
図7は、ニッケル酸化物とコバルト酸化物から構成される複合触媒の還元率の経時変化を示すグラフである。図8は、ニッケル酸化物と鉄酸化物から構成される複合触媒の還元率の経時変化を示すグラフである。また、図9に、図7に係るコバルト酸化物の還元率の経時変化を、図10に、図8に係る鉄酸化物の還元率の経時変化を示す。
また、触媒の還元率と還元操作時間の関係が判明するため、初期還元工程の所要時間を短縮することも可能となる。
