Fuel cell water cavity distribution structure and fuel cell

The invention relates to a fuel cell water cavity distribution structure and a fuel cell, the fuel cell water cavity distribution structure comprises an insulating plate, a fixed end plate, a first interface end plate and a second interface end plate which are connected in sequence, and a plurality of insulating manifolds arranged in the fixed end plate, each insulating manifold is matched and communicated with the two first holes in the insulating plate, and the first interface end plate is further provided with a plurality of second holes communicated with the insulating manifolds. And the second interface end plate is also provided with a third hole which is uniformly communicated with all the second holes in the first interface end plate. Compared with the prior art, the fuel cell has the advantages that the cooling liquid inlet and the cooling liquid outlet which are uniformly distributed on the single side of the bipolar plate are optimized for structural integration, and two-in-one, three-in-one and ot
