Description
2H2O → 2H2 + O2
この反応式は、水素と酸素が一定の体積比率(酸素の体積が1であるのに対して水素の体積は2)で生成されることを示す。
‐金属の基材、及び
‐上記基材上に設けられ、実質的に純粋な酸化ルテニウムからなるコーティング層
を備える。
a)金属基材の前処理;
b)酸化ルテニウムの適切な前駆体を溶媒へ溶解させることによる、活性溶液の調製;
c)金属基材への上記活性溶液の塗布;
d)金属基材へコーティングを固定するための最終熱処理の実行
を含む。
水の電解装置は、100cm2の作用表面を有し電極を収容する、60個の双極セルを備えるセルスタックと共に用いられた。電極を、円形状を有しており、微細孔を有する厚さ0.2mmのニッケルシートから切り出した。目打ち孔は、0.5mmの直径及び1mmの三角形ピッチを有する。各セルのカソード及びアノードは、厚さ0.5mmのポリスルフォン布の隔壁の介在によって分離される。薄いナイロンネットは、各電極と隔壁との間に挿入される。双極セルは、厚み0.5mmのニッケルシートの双極プレートによって互いに分離される。ニッケルの電極コレクタによって、電極と双極プレートとの間の良好な接触が維持される。
本実施例の水の電解装置は、600cm2の作用領域の電極を収容する48個の双極セルを備えるセルスタックを主体とする。電極は、円形であり、延伸された厚み0.2mmのニッケルシートから切り出され、横軸ピッチが1.3mmで縦軸ピッチが0.65mmであり、進展が0.25mmであるひし形の開口を有する。
24個のカソードを一組として鉛直方向に収容する支持体にカソードを挿入した。余剰の溶液を滴下除去した後、炉に入れて、300℃に保ち、6分間、わずかな空気循環下で乾燥させた。この操作の最後に、カソードを収容する支持体を炉から出し、開放空気中、室温下に放置して冷却した。
[実施例3]
室内実験を、100cm2の電極領域を有する10個の双極型の電解セルを備えるセルスタックを用いて準備した。スタックは、電解試験台に組み込まれ、電解試験台は、電源供給シミュレータを通じて120AまでのDC電流を供給可能である。再生可能であり、20分の期間中に圧縮された風力タービンの出力は、24時間の期間で記録された。実際、風力タービンの出力は、電解セルにおける高い様々な負荷を含み、対応する応力を伴う太陽光発電の出力よりも時間の制限が少ない。瞬間的な負荷は、DC電界全体における偏位を含み、不純物の混ざった水素の生成を避けるための、DC電流が5A未満に低下したときの自動中断を含む。試験期間における負荷中断は4回であった。
