Abstract
The invention relates to a fluid-cooled fuel cell, in which the cell surfaces are supplied with reaction media via axial supply ducts and radial distribution ducts, the distribution ducts being located in the cell surface and running along the edge of the cell surface, with the open side toward the active surface. According to the invention, the supply and distribution ducts in a fuel-cell stack are arranged such that distribution ducts are arranged in the edge region of the cell surfaces, as a result of stacking and staggering, in such a way that the inlet of the medium to the cell surface along a distribution duct is not carried out in a point-like manner, and that the entire cell surface is uniformly supplied with medium.
