アルカリ水電解は, 水素ガスを生成するための確立された工業プロセスです. セル内では, 陰極で水素ガスが, 陽極で酸素ガスが生成されます. 電解液は水溶液であり, 発生したガスが泡状になると, 実効イオン伝導率が低下します. また, 発生したガスは, 電極反応がアクセス可能な表面積を減少させることから, セルの性能に悪影響を及ぼす可能性があります. この例では, ガス生成がアルカリ電解セルの性能に与える影響を調査します. 詳細を見る

Impressed current cathodic protection is a commonly employed strategy to mitigate the ship hull corrosion where an external current is applied to the hull surface, polarizing it to a lower potential. In this model, the effect of propeller coating on the current demand is demonstrated. 詳細を見る
