Fuel cell assembly

A fuel cell assembly comprising at least a first flow field plate and a second flow field plate sandwiching a multilayer membrane electrode assembly,

• wherein the multilayer membrane electrode assembly comprises at least a 3-layer membrane electrode assembly comprising a first electrode facing the first flow field plate, a second electrode facing the second flow field plate and a membrane separating the electrodes,
• wherein the first flow field plate has a first flow field structure protruding from a first base level of the first flow field plate for distributing reactant over the first electrode, and the second flow field plate has a second flow field structure protruding from a second base level of the second flow field plate for distributing reactant over the second electrode,
• wherein further at least one sealing element is arranged between the first flow field plate and the second flow field plate, which is adapted to prevent leakage of reactants to an environment,
• wherein in a boundary area between the first flow field structure and the at least one sealing element, a first bypass stopping element is arranged for avoiding the reactant bypassing the first flow field structure, wherein the first bypass stopping element protrudes from the first base level of the first flow field plate,
• wherein the first bypass stopping element has a pointed portion, which is adapted to compress the multilayer membrane electrode assembly, and
• wherein the second flow field plate has a second bypass stopping element, wherein the first bypass stopping element and the second bypass stopping element are arranged opposite to each other, so that the first bypass stopping element and the second bypass stopping element form at least one bypass stopping element assembly, wherein the second bypass stopping element has a blunt portion, and wherein the blunt portion of the second bypass stopping element is adapted to be indented by the pointed portion of the first bypass stopping element.
