Abstract
Description
図1に示す有機ハイドライド製造装置(電解セル)に準じた構造を実施例1とした。以下、実施例1の有機ハイドライド製造装置の詳細について説明する。
実施例2の有機ハイドライド製造装置は、アノード基板として、短目方向中心間距離2.0mm、長目方向中心間距離4.0mm、板厚0.6mm、刻み幅0.6mm、開口率45%のエキスパンドメッシュを使用したこと以外は、実施例1と同様な構成である(表1参照)。
実施例3の有機ハイドライド製造装置は、電解質膜とアノードとの間のギャップを0.2mmとしたこと以外は、実施例2と同様な構成である(表1参照)。
実施例4の有機ハイドライド製造装置は、アノード基板として、短目方向中心間距離6.0mm、長目方向中心間距離10mm、板厚0.6mm、刻み幅1.0mm、開口率60%のエキスパンドメッシュを使用し、電解質膜とアノードとの間のギャップを0.02mmとしたこと以外は、実施例1と同様な構成である(表1参照)。
比較例1となる有機ハイドライド製造装置は、アノードとして日本べカルト社製Ti繊維焼結シートにIrO2をコーティングした電極を用いたことを除いて実施例1の有機ハイドライド製造装置と同様な構成とした。Ti焼結シートの多孔度は65%、平均孔径は約30mmである。
比較例2の有機ハイドライド製造装置は、アノードスペーサーを設けず、電解質膜とアノードとを密着させたこと以外は、実施例1と同様な構成である(表1参照)。
比較例3の有機ハイドライド製造装置は、アノード基板として、短目方向中心間距離3.0mm、長目方向中心間距離3.5mm、板厚1.0mm、刻み幅1.1mm、開口率20%のエキスパンドメッシュを使用したこと以外は、実施例1と同様な構成である(表1参照)。
比較例4の有機ハイドライド製造装置は、アノード基板として、短目方向中心間距離8.0mm、長目方向中心間距離12mm、板厚1.0mm、刻み幅1.1mm、開口率71%のエキスパンドメッシュを使用したこと以外は、実施例1と同様な構成である(表1参照)。
比較例5の有機ハイドライド製造装置は、電解質膜とアノードとの間のギャップを1.0mmとしたこと以外は、実施例2と同様な構成である(表1参照)。
図3に、定電圧電源によりアノードとカソードとの間に1.7Vを印加したときの実施例1の有機ハイドライド製造装置における電流密度の経時変化と定電圧電源によりアノードとカソードとの間に1.75Vを印加したときの比較例1の有機ハイドライド製造装置における電流密度の経時変化を示す。実施例1の方が比較例1よりアノードとカソードとの間の電圧が低いにもかかわらず、比較例1より高い電流密度が得られた。また、比較例1では初期に大きな電圧低下が認められ、試験終了後の観察から、Ti繊維焼結シート内に気泡の残留が認められた。このことから、実施例1は比較例1に比べて、アノード側で発生する酸素ガスが電極近傍に滞留することなく上部へ抜けるために、主としてアノード側ガスブロッキングに伴う過電圧上昇が起こらず、低い極間電圧でも高い電流密度が得られたと考察できる。また、実施例1において、カソード側の電位が不安定になることによる瞬時的な水素発生(有機物還元に対するファラデー効率の低下)は見られず、電解反応中のアノード状態が良好であることによって、カソード反応も好ましく進行していることが確認された。
