FUEL CELL DESIGN BASED ON A FRAMED BIPOLAR PLATE

摘要

This disclosure related to polymer electrolyte member fuel cells and components thereof. A fuel cell comprises an electrochmical package (5), a porous spacer (4), a second bipolar plate (2) having arrays of protrusions in its center portion, and a first bipolar plate (1) interposed between a first gasket (31) and a second gasket (32). The first bipolar plate (1) is a flat metal plate, but it can also be a non-flat plate that forms a space when placed against a flat surface, for example, one with undulating ridges and valleys, or with arrays of protrusions.
