Abstract
A bipolar plate assembly for a fuel cell is provided. The bipolar plate assembly includes a first unipolar plate disposed adjacent to a second unipolar plate. The first unipolar plate and the second unipolar plate are bonded by a plurality of localized electrically conductive nodes. A fuel cell stack including the bipolar plate assembly and a method for preparing the bipolar plate assembly are also described.
