Abstract
Description
2H2O ⇒ O2 + 4H+ + 4e− (OER)
4H+ + 4e− ⇒ 2H2 (HER)。
(a)OERにおいてアノード側で形成された酸素により引き起こされ得る腐食に起因して、炭素ベースの材料(例えば、カーボンブラック上に担持されたPt/C触媒、または炭素繊維ベースのガス拡散層「GDL」)は、電解MEEのアノード側で使用できない。
(b)電解プロセスは、頻繁に、水素の貯蔵のための与圧を実施するために、水素側で、高圧下で実施される。現在のところ、15バールまでの圧力(例外の場合、30バールまで)に到達している。このことは、電解MEEが、従来のPEM燃料電池の作動よりも約5〜10倍高い、アノードとカソードとの間の差圧に供されることを意味している。このことは、MEEの安定性および圧力抵抗性に対する要求を増加させる。従って、比較的厚い膜材料(200μmの厚さまで)を使用することが好ましい。しかし、本願に記載される新規MEE構成の概念はまた、この圧力安定性を増加させる必要がある。
(c)水素だけではなく、酸素までもが、電解プロセスの間に解放されるので、漏電の場合には、潜在的な水素/酸素ガス爆発の危険がある。反応物質は、このような作用を避けるために、互いに厳密に分離されていなければならない。このことは、電解MEEの気密性に対する要求を増加させる。
(d)さらに、電解MEEのために、異なる触媒が使用されなければならない。イリジウムは、塩素および酸素の生成のためのプロセスに関してその固有の電解特性が知られている。従って、イリジウムは、純粋な金属(「ブラック」として)または酸化物の形態のいずれかで、適切な場合は、他の酸化物との混合物として、アノード側での酸素放出反応(OER)のための好ましい材料である。電解MEEのための適切なアノード触媒は、例えば、本出願人による独国特許出願公開第P 1 0350 563.6号に記載される。全ての貴金属の中でも、白金は、カソード側の水素放出反応(HER)に最も活性な触媒であり、電解MEEのカソード触媒として頻繁に使用されている。
4層の電解MEE(図1を参照のこと(ただし、ガス拡散層(5)なし))を製造するために、第1の工程において、片側をコーティングした膜を製造する。対応する膜(Nafion(登録商標)N117,DuPont)を、EP 1 1027 385に記載されるようなスクリーン印刷によって、その全領域にわたってアノード触媒でコーティングする。酸化イリジウム粉末(BET表面積 30約m2/g、Umicore製)を使用する。この触媒インクは、以下の組成を有する:
5層電解MEE(図2を参照のこと)の製造を、原則的には実施例1に記載したように実施する。しかし、炭素ベースでないガス拡散層(この場合は、5×5cmの寸法、厚さ0.09mmを有する多孔性の不織布構造体、Bekinit(登録商標)チタン繊維から製造される、Baekaert,Zwevegem,オランダ製)を、第4の工程(すなわち、シーリング材の塗布)を実施する前に、アノード側のアノード触媒層に直接置く。シーリング材の枠の全体の高さは、実施例1と比較すると、チタン不織布の厚みだけ増加する。
