A liquid-cooled, bipolar plate (8) separating adjacent cells of a PEM fuel cell comprising corrosion-resistant metal sheets (58), (60), (110), (116), (85), (87) brazed together so as to provide a passage between the sheets (58), (60), (110), (116), (85), (87) through which a dielectric coolant flows. The brazement (85), (124) comprises a metal which is substantially insoluble in the coolant. <IMAGE> |
