Abstract: A component of an electrochemical cell, the component including a metal substrate and a layer system that is at least partially electroplated onto the metal substrate; the layer system optionally includes a first layer disposed on the metal substrate, and includes at least one second layer that is disposed on the metal substrate or, if applicable, on the first layer, the optional first layer being made of copper or nickel, and the at least one second layer being made of an alloy including at least two of the elements tin, copper, nickel, silver, zinc, bismuth, antimony, cobalt, manganese, tungsten, nonmetal particles having electrically conductive particles being incorporated into the alloy. The component forms in particular an electrode for a redox flow cell or a flow field plate for a fuel cell or an electrolyser.

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.
