Abstract: A method for producing a bipolar plate for an electrochemical cell, wherein a fluid-impermeable carrier is provided and a fluid-impermeable coating is applied to at least one subregion of a surface of the carrier, wherein the coating is applied by at least one of cold gas spraying, plating, in particular roll cladding, or high-velocity flame spraying, in particular with air or oxygen as a combustion gas. A bipolar plate for an electrochemical cell.

Abstract: A component for an electrochemical cell, wherein the component is present in the form of an electrode for a redox-flow cell or in the form of a bipolar plate for a fuel cell or an electrolyzer or in the form of a fluid diffusion layer for an electrolyzer, including a substrate which is formed from a material in the form of a metal sheet and/or an expanded metal grille, wherein the material is formed from a tin-nickel alloy or a tin-silver alloy or a tin-zinc alloy or a tin-bismuth alloy or a tin-antimony alloy. A redox-flow cell, a fuel cell and an electrolyzer are also provided.
