In the planned transition toward a CO2 neutral economy and industry, hydrogen plays a significant part. In the production of hydrogen catalysis is of great importance, necessitating better and cheaper catalysts. To make high-performance electrodes cheaper, they will need to be produced in series. To establish this the H2Giga project was started. One promising method here in is the plasma treatment of the electrodes, with which various material properties can be enhanced, such as increasing the surface area or improving the adhesion of catalyst particle coatings. The method is viable for scaling and roll to roll production. The experimental setup and procedure used for the plasma treatment is discussed. Various electrode materials are treated, such as nickel, nickel with catalyst particle coatings, copper and others. The results are investigated using a scanning electron microscope, electrochemical tests and adhesion tests. The results are presented and possible future steps are discussed.
