Bipolar plate for fuel cell or electrochemical reactor and plate usage in a fuel cell stack or electrochemical reactor

摘要

A bipolar plate (10) for a fuel cell or chemical reactor is described comprising one distribution component (1) on each side of ametal layer for distribution of a gas across the surface of a cathode and the surface on an anode. The distribution components are constituted by rectangular gas distribution layers (1), which are fixed soldered centred onto the metal layer. Gas flow channels (5) are arranged for transverse flow along opposite edges of the gas distribution layer. A compact design with a particularly low through-flow resistance is in this way achieved.
