BIPOLAR FUEL CELL PLATE

Abstract

An industrial-scale PEM-type bipolar plate comprising a first active area face (14), anode or cathode, intended to contact a membrane (12), and a second face (15) intended to contact a terminal plate (13) or another bipolar plate. The bipolar plate comprises: through-holes (2, 3, 4, 5, 6), gas channels (7) on the first face (14) for conducting reactant gases, at least one cooling channel (1) on the second face (15) for conducting coolant, and first barriers (8) arranged in the gas channels (7) having the following geometries: quarter-cylinder, rectangular prism, and another quarter-cylinder; and second barriers (9) having a triangular prism geometry arranged in the gas channels (7) after each of the first barriers (8).
