Patent ID: 8557477

Claim:
A fuel cell stack, comprising: a first end plate, comprising: a first end plate structure component; and a first end plate manifold component, combined with the first end plate structure component, a rigidity of the first end plate structure component being greater than a rigidity of the first end plate manifold component, the first end plate manifold component having at least one first open manifold, at least one first close manifold and a first concave, wherein the first end plate structure component is inlaid to the first concave; a second end plate, comprising: a second end plate structure component; and a second end plate manifold component, combined with the second end plate structure component, the first end plate manifold component and the second end plate manifold component being disposed between the first end plate structure component and the second end plate structure component, a rigidity of the second end plate structure component being greater than a rigidity of the second end plate manifold component, the second end plate manifold component having at least one second open manifold and at least one second close manifold; at least a fuel cell, disposed between the first end plate manifold component of the first end plate and the second end plate manifold component of the second end plate, and having a plurality of flow channels respectively connected to the corresponding first open manifold, the first close manifold, the second open manifold and the second close manifold; a plurality of external pipelines respectively connected to the first open manifold and the second open manifold for leading reaction fluid or cooling fluid required by the fuel cell, wherein the first open manifold and the second open manifold respectively separate the corresponding first end plate structure component and the corresponding second end plate structure component from the reaction fluid or the cooling fluid; a first current collector, disposed between the first end plate manifold component and the at least one fuel cell; and a second current collector, disposed between the second end plate manifold component and the at least one fuel cell.
