Abstract
A bipolar plate for use in a fuel cell stack includes a first delimiting surface and a second delimiting surface that is arranged parallel to the first delimiting surface, wherein the delimiting surfaces are arranged spaced apart from one another and define an intermediate space, wherein the bipolar plate includes at least one fuel cell section having a flow field that has depressions that protrude into the intermediate space and is provided so as to make direct contact with a fuel cell, and the bipolar plate includes at least one cooling section that extends therefrom along the delimiting surfaces, wherein at least one heat pipe is arranged in the intermediate space and extends so as to transfer heat from the fuel cell section into the cooling section.
