Es wird ein Verfahren zur Herstellung einer elektrisch leitfähigen Kontaktschicht auf einem oxidationsbelasteten Bauteil vorgeschlagen, bei dem ein Bauteils umfassend eine Legierung (27) auf Titanbasis, die als Legierungselement zumindest ein Edelmetall in einer Titanmatrix (33) aufweist, bereitgestellt wird. Es wird ein Ätzmittel auf einer Oberfläche (35) des Bauteils angewendet, wobei Material der Titanmatrix (33) selektiv abgetragen wird. Dabei wird von Material des Legierungselements derart freigelegt, dass oberflächennah eine elektrisch leitfähige Kontaktschicht (29) ausgebildet wird, die das Edelmetall aufweist. Die Kontaktschicht (29) kann wahlweise als eine poröse Schicht ausgebildet sein mit einer über den Ätzprozess einstellbaren Porosität.Das Verfahren ist anwendbar zur Herstellung einer Kontaktschicht auf oxidationsbelasteten Bauteilen einer elektrochemischen Zelle, wie etwa Bauteile einer Elektrolysezelle (1) oder einer Brennstoffzelle, insbesondere eine Bipolarplatte (21a, 21b) oder eine Gasdiffusionslage (11a, 11b) mit einer Legierung (27) auf Titanbasis.

VALVE DEVICE FOR SELECTIVELY OPENING AND CLOSING LINES IN A FLOW BATTERY, AND FLOW BATTERY HAVING A VALVE DEVICE

Resumen de: WO2025195611A1

The invention relates to a valve device (1) for selectively opening and closing two lines (111) in a flow battery (100). The flow battery may be a redox flow battery, a semi-solid flow battery, or a solid flow battery, and the flow battery comprises two valves (2), each of which is designed to selectively open and close an electrolyte-conducting line. The valve device further comprises a drive (3), said drive being coupled, as a common drive, to both valves in order to control the valve position of both valves.

The first tightening unit (5) and the second tightening unit (4) are independent of each other.

RECYCLING OF CATALYST COATED MEMBRANE COMPONENTS

Resumen de: CN119948093A

A method of recovering a fluorinated polymer from a membrane comprising the fluorinated polymer, the fluorinated polymer comprising a fluorinated polymer backbone and a plurality of groups represented by the formula-SO3Z wherein Z is hydrogen, the method comprising: contacting the membrane with an agent providing a source of cations to form a fluorinated polymer salt wherein Z is a cation, wherein the agent is maintained at a temperature sufficiently low such that the membrane remains in a solid, undispersed form; removing excess unreacted reagent from the solid fluorinated polymer salt; and after removing the excess reagent, dispersing the solid fluorinated polymer salt in a solvent.
