Abstract
The present invention relates to a bipolar plate for a low-temperature fuel cell, in particular for a polymer electrolyte fuel cell, including a metal substrate with a coating on a surface of the substrate, the coating including an organic polymer and an electroconductive filler. The organic polymer is formed by chemical reaction of at least two components, including a bi- or polyfunctional isocyanate compound as the first component and one or more compounds having at least two free hydroxy or amino groups, as the second component.
