Abstract: A method for monitoring voltage drift includes measuring a voltage across a diode of a power device, providing the measured voltage as an input to a controller, the controller being configured to run a transformer-based model, and forecasting a range of expected future values of the voltage across the diode of the power device with the transformer-based model. The transformer-based model may include a temporal fusion transformer with a temporal convolutional neural network and an adversarial compensation model with a backpropagation algorithm.

Abstract: An anode for oxygen evolution in electrolytic processes comprising a nickel-based planar substrate having a first side and second side and a porous catalytic coating formed on at least one side of the substrate, wherein the porous catalytic coating exhibits a lamellar morphology made from metallic patches and void patches, the metallic patches being made from a material selected from nickel, nickel oxide, a nickel-aluminium alloy, or combinations thereof.
