Abstract (en)
[origin: WO2005096001A1] The invention relates to a device for determining the distribution of current density in a fuel cell or in a fuel cell stack comprising at least one fuel cell having two bipolar plates (9), a membrane/electrode unit (12) and an end plate (8). The inventive device is characterized by at least one segmented, conductive plate (7) that is interposed between a bipolar plate and an end plate, every segment of said plate being electrically contacted via two wires (6) via contact points. In contrast to prior art, where often individual electrodes or flow fields are segmented for determining the distribution of density, the fuel cell to be examined remains unchanged when the inventive device is used. The additional segmented plate and optionally additional plates can simply be removed once the distribution of current density has been determined for this fuel cell.
