The utility model relates to the field of fuel cells, and provides a fuel cell stack which comprises a plurality of fuel cell single bodies which are sequentially stacked, each fuel cell single body comprises a bipolar plate and a membrane electrode assembly, and each membrane electrode assembly is located between every two adjacent stacked bipolar plates. Wherein a plurality of first reaction areas on the bipolar plate are in one-to-one correspondence with a plurality of second reaction areas on the membrane electrode assembly, a reaction area flow field is formed on each first reaction area,and the reaction area flow fields between the adjacent first reaction areas of each bipolar plate are the same or symmetrically arranged; the areas of the independent first reaction areas of the bipolar plates are the same, and the areas of the independent second reaction areas of the membrane electrode assemblies are the same. According to the fuel cell stack, on the basis of an existing fuel cell stack, the reaction ar
