Abstract
【解決手段】3.856〜3.885Åの格子定数値を有し,粒子サイズが2〜5nmであり,担体に担持されたPt/Ru合金触媒は耐CO被毒性にすぐれる耐CO被毒性がすぐれるために,使用上でさらに活性が優秀である。すなわち,少量の触媒を使用しても寿命のさらに長い電極及びこれを採用した燃料電池を製造できる。
【選択図】図2
Description
塩化白金酸水和物(H2PtCl6・xH2O)1gを水25mlに入れて撹拌させて完全に溶解させ,これと別途に塩化ルテニウム水和物(RuCl3・H2O)0.44gをやはり水25mlに入れて撹拌させて完全に溶解させた。前記の通りに製造されたそれぞれの溶液を混合して金属塩溶液を製造した(図2のS1)。
実施例1と熱処理した時間及び温度だけを下記表1のように異ならせ,格子定数とPt/Ru含有量とを測定した。その結果,下記表1に表したような結果を得た。
実施例1とは,下記表2に表した点でのみ異ならせ,実施例6〜実施例9とした。
商用触媒を利用して物性を測定した。ラベル上では,PtとRuとの合金比が50対50(比較例1及び比較例2),または33対67(比較例3)と記載されているが,Gasteigerらの論文の分析通り実体測定された合金比などを分析してみた結果,下記表4に表した通りである。
前記実施例4で製造したPt/Ru触媒を利用して燃料電池用電極を製造した。担持触媒で,Pt/Ruの質量比は,70質量%であった。アノード電極への触媒ローディング量は,3.8mg/cm2であり,カソード電極には,白金ブラック触媒が6.3mg/cm2ローディングされていた。
