Description
アノード:H2→2H++2e− (1)
カソード:O2+4H++4e−→2H2O (2)
E゜アノード=0V/ENH
E゜カソード=1.23V/ENH
H2+1/2O2→H2O E゜eq=E゜カソード−E゜アノード=1.23V
以下の構造を有する第1のイオノマーと、
‐ポリマー膜と、
‐少なくとも2つのペルフルオロスルホン酸イオノマーを含む、本発明による活性層から形成される‐カソードと、
場合によっては本発明による活性層から形成されるアノードと、を少なくとも含む。
MEA(膜電極接合体)の形成は、3つのステップで実施される。
第1のステップは、イオノマーおよび炭素質担持体上の触媒を溶媒中に含む、触媒インクを調製する段階を含む。
第2のステップは、以降で説明する方法によって、拡散層上にインクを堆積することによって電極を製造する段階である。
第3の製造ステップは、活性層中に存在するイオノマーの1つと同一のポリマーから一般的にできている膜を挟んで2つの電極(カソードおよびアノード)を組み立てる段階である。
本発明によると、アノードの組成は、カソードの組成と異なる。以下の割合は、乾燥触媒層における重量として理解されるべきである。
単一のイオノマーを含むMEAの製造手順は、前述と同一である。唯一異なる点は、カソードを製造する段階である。カソードはアノードと同一の材料、つまり触媒75%およびイオノマー25%で作製される。
装置の性能は、自動車向け用途に推奨されるものに近い条件で調査される。
