Abstract
A fuel cell stack with a plurality of membrane electrode assemblies (MEAs) and a plurality of bipolar plates, wherein at least one surface of a first bipolar plate runs in undulating fashion, meandering fashion or zig-zag-shaped fashion and extreme points of the surface of the bipolar plate make contact with a first surface of a MEA at contact points. At least some of the contact points are associated with mating contact points on a second surface of the MEA, which surface is opposite the first surface of the MEA, with a surface of a second bipolar plate making contact with said mating contact points, and that the contact points and the associated mating contact points are positioned one above the other in the stacking direction. A method for producing a fuel cell stack is provided. A bipolar plate for a fuel cell stack is also provided.
