A method and device for conversion of water into hydrogen peroxide, wherein a corona discharge zone is generated between a rotating electrode formed as a hollow rotor of a centrifugal fan and a fixed electrode. The rotating electrode is rotated relative to an insulation layer of the fixed electrode, and high voltage AC power is applied to the fixed electrode while conveying vapor through the corona discharge zone. In one aspect, the novelty resides in using the rotating electrode for conversion of water to vapor. In another aspect, conductivity between the two electrodes induces electrolysis, which is used for high voltage AC transmission to the rotating electrode.

The invention relates to a metallic bipolar plate for use in an electrochemical cell, wherein the bipolar plate comprises an electrically conductive graphene-like coating. The graphene-like coating has a layer thickness between 10 nm and 1 μm. Chemical synthesis is initially carried out to produce the graphene-like coating according to the invention comprising one or more at least partially reduced graphene oxide layers. Proceeding from graphite powder, a graphite oxide powder is initially produced, which is subsequently converted into a stable graphene oxide (GO) suspension by way of ultrasonic dispersion. By depositing this suspension on a metallic carrier substrate (bipolar plate), thin graphene oxide layers can then be applied and subsequently be reduced to obtain at least partially reduced graphene oxide (rGO), which is referred to as graphene-like. This coating advantageously has sufficient stability and the necessary electrical conductivity for use in an electrochemical cell.
