PEM水電解水素エレクトロリーでのチタン繊維フェルトの拡散層の製造およびコーティング処理を行います

エキスパートのコアの視点: PEM電解タンクには、二板、ガス拡散層、電極の3つのコアコンポーネントがあります。 現在、ダイプレートとガス拡散層を局在化することができ、国内の膜電極は開発中です。 バイポーラプレートの生産ラインフローは、基本的に半導体やチップの生産ラインフローと同じであり、フィード、洗浄剤、そして徐々に露光、開発、修復、高温焼け入れ、エッチング、 復調、検査、完成品はプロセス完了後に保管されます。材料の選択において、金属バイポーラプレートは、ステンレス鋼、チタン合金、ニッケル系合金など、あらゆる種類の金属および合金に適した幅広いオプションを備えています 一定の耐用年数を確保するために、次のことを行います。 二重プレートおよびガス拡散層は、表面にコーティングする必要があります。通常はプラチナ、イリジウム、金、カーボンベース、およびその他の導電性防錆コーティングを使用します。 コーティング厚みの選択では、現在の一般的な化学電気めっきコーティングは厚さが約0.1 mmで、F ü rthのコーティングプロセスは0.1マイクロメートルを達成でき、金めっきでは100ナノメートルの厚さを達成できるため、コストを削減できます。 真空でのコーティングおよび操作前のプラズマクリーニングにより、ガス堆積は水コーティングよりも結合度が高くなります。 チタン繊維フェルト拡散層のオプション材料には、チタン、ニッケル、ステンレス、合金などがあります。 しかし、ニッケルベースの繊維には技術的な障壁があり、市場価格は高く、繊維材料を個別に処理し、顧客の要求に応じてカスタマイズされた加工製品を提供できるという利点があります。 現在、アルカリ性電解水水素製造技術と比較して、PEM水素製造ではコア材料の規模と位置の大きさが認識されておらず、設備コストも高くなっています。 二重プレートとガス拡散層は、PEM電解水のコアコンポーネントです。 コア部品の技術的最適化と位置決めを実現することで、PEM電解タンク装置のコストを大幅に削減し、水素エネルギー産業を推進することができます。
