FUEL CELL ASSEMBLY

Disclosed is a fuel cell assembly (8) comprising at least a first flow field plate (2) and a second flow field plate (4) sandwiching a multilayer membrane electrode as- sembly (10), wherein the multilayer membrane electrode assembly (10) comprises at least a 3-layer membrane electrode assembly (11) consisting of a first electrode (12) facing the first flow field plate (2), a second electrode (14) facing the second flow field plate (4) and a membrane (13) separating the electrodes (12; 14), wherein each flow field plate (2; 4) has a flow field structure (22; 42; 23; 43) pro- truding from a base level (24; 44) of the flow field plate (2; 4) for distributing reac- tant over the respective electrode (12; 14), and wherein further at least one sealing element (52; 53; 54; 55; 56; 57; 58; 59) is arranged between the first and the sec- ond flow field plate (12; 14), which is adapted to prevent leakage of the reactants to an environment, wherein in a boundary area (26; 46) between the flow field structure (22; 42; 23; 43) and the sealing element (58; 59) of at least one of the flow field plates (12; 14) at least one bypass stopping element (60; 70) is arranged for avoiding the reactant bypassing the flow field structure (22; 42; 23; 43), wherein the bypass stopping element (60; 70) protrudes from the respective base level (24; 44) of the flow field plate (12; 14), wherein the at least one bypass stop- ping element has a pointed portion (66), which is adapted to compress the multi- layer membrane electrode assembly (10), as well as a flow field plate for such a fuel cell assembly.
