催化涂覆的阴离子交换膜的生产

Absstract of: WO2025153355A1

The invention relates to catalytically coated anion exchange membranes and to the production thereof. The catalytically actively coated anion exchange membranes are used in electrochemical cells, especially for water electrolysis. The invention addresses the problem of providing a method for producing an electrocatalytically actively coated anion exchange membrane, the coating of which is porous and thus the electrocatalytically active centres located in the coating are easily accessible for the reactants. A basic concept of the method according to the invention consists in incorporating particulate inorganic material into the catalyst coating as a placeholder, solidifying the coating, and subsequently leaching the inorganic material out of the coating again. As a result of the leaching, the inorganic material is converted into a water-soluble product which can easily be washed out of the coating. Cavities (pores) remain at the points where the particulate inorganic material was previously located within the coating. Within the coating composition, the inorganic material therefore assumes the function of a structuring means which is lost in the course of the catalytically active coating.

Absstract of: EP4790036A1

The present invention relates to the technical field of sealing materials, and discloses a high-temperature vermiculite sealing material for SOFC, and a preparation method thereof. The material is prepared from modified chemically expanded vermiculite and negative-ion high-temperature expanded vermiculite. The modified chemically expanded vermiculite carries positive charges, and the negative-ion high-temperature expanded vermiculite carries negative charges. After the modified chemically expanded vermiculite and the negative-ion high-temperature expanded vermiculite are mixed, electrostatic attraction is generated to achieve combination. The material does not use binders, so that the loss on ignition is significantly reduced without changing the combined strength of the sealing material. The stearate serves as an intercalation agent of chemically expanded vermiculite. The modified chemically expanded vermiculite prepared from the stearate has high-temperature resistant compressive strength at 700°C. The negative-ion high-temperature expanded vermiculite is formed by using negative ion air to treat high-temperature expanded vermiculite to enable the high-temperature expanded vermiculite to load and accumulate negative charges. Using the negative ion air to treat the high-temperature expanded vermiculite does not require the use of chemical agents, the process is simple, and large-scale production can be achieved.

In the first state, power is supplied from an electric path (70) to a storage battery facility (30). In the first state, a water electrolysis facility (40) does not perform water electrolysis. In the second state, power is supplied from the electric path (70) to the storage battery facility (30). In the second state, power supplied from the electric path (70) to the water electrolysis facility (40) is larger than power supplied from the electric path (70) to the water electrolysis facility (40) in the first state.
