  • Patent number: 11208713
    Abstract: A method is described that can be used in electrodes for electrochemical devices and includes disposing a precious metal on a top surface of a corrosion-resistant metal substrate. The precious metal can be thermally sprayed onto the surface of the corrosion-resistant metal substrate to produce multiple metal splats. The thermal spraying can be based on a salt solution or on a metal particle suspension. A separate bonding process can be used after the metal splats are deposited to enhance the adhesion of the metal splats to the corrosion-resistant metal substrate. The surface area associated with the splats of the precious metal is less than the surface area associated with the top surface of the corrosion-resistant metal substrate. The thermal spraying rate can be controlled to achieve a desired ratio of the surface area of the metal splats to the surface area of the corrosion-resistant metal substrate.

  • Patent number: 9567681
    Abstract: Methods for providing a metal surface structure and treatment process to prevent the corrosion (e.g., high electrochemical potential oxidization and hydrogen embrittlement) of a metallic component used in electrolyzer operational conditions. The oxide surface scale of a metal plate is used to prevent the corrosion, and electrical conductive materials such as e.g., precious metals or carbon are used to provide the surface electrical conductance of the metallic components. The methods advantageously produce, at a low cost, metal components for electrolyzers that need high electrical conductance and corrosion resistance for long term operation.
