NOVELTY - The distribution plate has two metallic plates (11, 12) with respective inner and outer surfaces. The outer surface (11o) of the plate (11) cooperates with an ion-exchange membrane, and has a gas distribution duct system (111) for distributing gas e.g. fuel gas. A coolant circulating duct system (122) circulates a coolant i.e. water, and is arranged on one of the inner surfaces of the plates or on both the inner surfaces. The plates are joined by a layer of an electrically conductive connection material covering the inner surface of each plate.    USE - Metallic plate i.e. bipolar plate, for distributing fluid e.g. fuel gas and oxidant gas, in a fuel cell of a motor vehicle, and for being arranged between elementary electrochemical cells of the fuel cell. Can also be used for an end plate that is installed on both sides of a stack of different electrochemical cells of the fuel cell.    ADVANTAGE - The arrangement of the plate ensures the utilization of the fuel cell in the motor vehicle in an easy manner, and permits to obtain high ratio of power delivered with respect to the weight and the encumbrance of the fuel cell. The plate ensures better robustness, and avoids the problem of electrical contact loss. The electrically conductive connection material covers the inner surfaces of the plates, thus obtaining a brazing between the plates to ensure better electrical contact, and guaranteeing an optimal sealing between the coolant circulating duct system and the exterior, and between the coolant circulating duct system and the gas distribution duct system.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for fabricating a distribution plate made of steel, for a fuel cell.    DESCRIPTION OF DRAWING(S) - The drawing shows an exploded view illustrating different elements of a bipolar plate.
