NOVELTY - A bipolar collector for a solid polymer electrolyte fuel cell, having metal cylinders which extend through a polymer plate into the electrodes, is new.    USE - For a solid polymer electrolyte fuel cell.    ADVANTAGE - The collector has excellent conductivity, allowing fuel cell operation at high current densities, and has low weight and low production cost.    DETAILED DESCRIPTION - A bipolar collector, for a solid polymer electrolyte fuel cell, is traversed perpendicularly by uniformly distributed metal cylinders which project into the electrodes and which are spaced apart by a minimal distance of 2-4 mm, sealing between the collector faces being ensured by a polymer plate in which the cylinders are inserted symmetrically.    Preferred Features: The polymer plate may have fluid transport channels on its two faces, in which case the cylinders are positioned in relief portions between the channels to create a square or rectangular distribution pattern. Alternatively, the polymer plate is free from fluid transport channels but may have studs for spacing the electrodes from its surface, in which case the cylinders are positioned to create an equilateral triangular pattern. The space is filled with a fluid transporting and distributing macroporous structure consisting of a metal or alloy, having its exposed surface coated with a corrosion protective film having hydrophobic properties to facilitate water evacuation, or of a polymer. The metal cylinders are 0.1-0.3 mm diameter stainless steel cylinders which project by 0.1-0.3 mm from the polymer plate, the projecting portions being covered with a cathodically deposited thin film of precious metal such as gold or a platinum group metal. The metal cylinders are inserted during moulding of the polymer plate or are inserted into the molded polymer plate by a mechanical operation such as riveting or stitching with a stainless steel wire.
