Abstract
【解決手段】燃料電池用電極は、1乃至5nmの平均粒径を有する白金ブラックまたは白金−遷移金属ブラック触媒を含む触媒層及び導電性機材からなる電極支持体を含む。また、ブラック触媒を製造した後、カーボン支持体を合わせようとする組成にすることで、カーボン担持された触媒も容易に製造できる。
【選択図】図2
Description
ミネラルオイル中に分散されている常用化された鉄−ナノサイズの活性鉄粉末(Aldrich社)を使用した。この鉄粒子のTEM写真を図3に示したが、図3によれば、粒子が非常に大きいことが分かる。
実施例1の触媒を1Mの硫酸条件で処理して、白金ブラック触媒を製造した。
ミネラルオイル中に分散されている常用化された鉄−ナノサイズ活性鉄粉末(Aldrich社)とテトラアミン塩化白金(II)水和水溶液を容器中で機械的方法で混合した。
