FUEL CELL BIPOLAR SEPARATOR PLATE

摘要

A bipolar separator plate for a fuel cell stack constructed of at least two coextensive sheet metal elements shaped to promote the distribution of reactant gases to the electrodes of the fuel cell units of the fuel cell stack. The coextensive sheet metal elements are corrugated and fitted together to form at least one coolant flow channel between corresponding peaks, or valleys, of the corrugations of the sheet metal elements.
