摘要:
Energy storage modules generally include a housing with component parts arranged therein. The component parts are in this case either capacitors, for example double-layer capacitors and/or electrolyte capacitors. According to the invention, a filler is provided in the housing and binds electrolyte liquid occurring in the even of damage or else electrolyte gases. Beds of material with a large specific surface area, such as zeolites or else active carbons, are suitable as fillers. The surfaces are also possibly catalytically coated.

An energy management system includes a control unit and an electrolysis system having an alkaline electrolysis unit and a PEM electrolysis unit. The control unit controls the electrolysis units independently of one another in such a way that a performance adjustment of an overall performance of the electrolysis system is particularly dynamic.
摘要:
In a method for treating sludge (1), at least two electrodes (2) are provided for generating an electric field. Water present in the biosludge is electrolyzed and OH° radicals (OH°) are generated at least in part.

A method for producing a hydrophobic coating for condensers to obtain a dropwise condensation, a hydrophobic coating for condensers, a hydrophobically-coated condenser, and a coating agent are provided. A coating agent is applied to a condenser. The coating agent includes a liquid solvent and a coating material. The coating material may be applied by a wet-chemical method.
摘要:
A gas diffusion electrode for a PEM fuel cell includes a metallic catalyst, and an electrocatalyst layer having a polymer A for hydrophobicizing the electrocatalyst layer and a uniform thickness of between 3 to 40 μm, especially 25 μm. The polymer A content is less than 10% by weight based on the metallic catalyst content. Methods of producing and of hydrophobicizing the electrode include screen printing a paste onto a carrier and removing the screen-printing medium by heating. The paste includes at least one metallic catalyst with a content of polymer A up to at most 10% by weight, and a screen-printing medium. The electrocatalyst layer of the electrode has a significantly lower content of the catalyst inhibitor TEFLON® because it is not added only to the screen-printing paste but is subsequently applied, with the same surface-specific effect, by dipping the finished electrocatalyst layer in a solution containing TEFLON®.

The invention is directed to a battery with liquid cooling composed of at least two fuel cells that respectively comprise a negative pole plate, a membrane electrode unit and a positive pole plate that are connected to one another mechanically rigidly, gas-tight and electronically insulating by a frame element, whereby the battery is immersed into a coolant bath.
摘要:
Solid electrolyte capacitors are produced in such a way that a formed metallic anode body which has pores passing through it is arranged on a working electrode, and a conductive polymer is deposited in the pores of the anode body by electochemical polymerization of a monomer in the liquid phase, in the presence of a conducting salt. The polymer is provided with a contact point.
