IONOMER COATED ELECTRODE

摘要

The present application relates to a use of an ionomer coated electrode (2) for controlling electrical potential of a fluid (6) in a high-voltage device (1). It also relates to a fluid-filled high-voltage device e.g. a HVDC converter, (1) comprising a plurality of ionomer coated electrodes (2) for controlling electrical potential of the fluid (6). In a preferred embodiment, the electrode comprises a titanium or palladium core coated with NAFION as ionomer. Optionally, the titanium can be coated with an electrocatalytic layer comprising iridium oxide (lr2O3) or ruthenium oxide (RuO2).
