Gels as battery separators for soluble electrode cells [PDF]
, 1977 Gels are formed from silica powders and hydrochloric acid. The gels are then impregnated into a polymeric foam and the resultant sheet material is then used in applications where the transport of chloride ions is desired.

Perfluorinated ion exchange membrane.
Journal of Ion Exchange, 1995 フッ素系イオン交換膜の膜素材ポリマーの特性と, 食塩電解用隔膜の膜構造について概説した。電解用隔膜には, 高い電流効率と低い電気抵抗, および高い機械的強度が要求される。これらを達成するため現状の工業用膜は, 多層の樹脂層をPTFE織布で補強した複合膜構造となっている。陰極側の樹脂層には, カルボン酸をイオン交換基とするポリマーのみが高濃度の苛性ソーダ中で高い電流効率を実現するため, カルボン酸ポリマーが用いられる。陽極側の樹脂層には, イオン導伝性の高いカルボン酸あるいはスルホン酸ポリマーが用いられている。また, より高度な複合膜設計に基づいて, 50%力性ソーダを直接電解で製造可能な膜も開発されつつある。加えて近年, 燃料電池の固体電解質としてフッ素系スルホン酸ポリマーの適用が期待されており ...

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production
Advanced Functional Materials, EarlyView.Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister
