Description
引用した米国仮特許出願第60/580,739号の実施例に従って、一連のガス拡散電極を作製した。違いは、パターン形成された貴金属被膜を得るために、一連のマスクをガス拡散媒体とIBAD源の間に挿入したことである。引用した出願の場合のように、適用する貴金属として白金を選択した。ガス拡散媒体は、410ミクロンの全厚、210g/m2の基本重量、0.54g/cm3の密度、525mΩcmの電気抵抗、0.84ガーレーの空気透過性、6ミクロンの平均孔径で25ミクロンの間隙率、および5000ガーレー秒の平均平滑度である、Shawiniganアセチレンブラックカーボン粒子とPTFEの混合物で被覆された立体カーボン織布から成るものを選択した。そのようにして得られたガス拡散媒体を同量の試験片に分割し、その各試験片を、化学エッチングされたステンレス鋼シートから成る適当なパターン形成されたマスクを重ねた後、白金金属のデュアルIBAD蒸着にかけた。表面を洗浄し、部分的にテクスチャー加工するために、200〜500eVの第1の低エネルギービームが照射され、続いて、1000〜5000eVの白金イオンが、約50nmの全厚に対応する、約0.08mg/cm2の白金の被膜を成長させるまで、照射された。表1に記載された格子パラメータを有する、図3の開示に従う9個の異なる六角形の格子を使用した。
