Abstract:
1. A current sensor assembly that monitors current flow through segments of a fuel cell stack, comprising: a first plate including a first non-conductive substrate having a first plurality of conductive pads each deployed on and defining a distinct segment of a first surface of the first non-conductive substrate and a first flow field formed in a surface of said first non-conductive substrate opposite said first surface, wherein each of the first plurality of conductive pads is in electrical communication with a plurality of conductive paths that are through the first non-conductive substrate; a second plate including a second non-conductive substrate having a second plurality of conductive pads each deployed on and defining a distinct segment of a second surface of the second non-conductive substrate and a second flow field formed in a surface of said second non-conductive substrate opposite said second surface, wherein each of the second plurality of conductive pads is in electrical communication with a plurality of conductive paths that are through the second non-conductive substrate; and a sensor unit operably disposed between said first surface of said first plate and said second surface of said second plate, wherein the sensor unit monitors current flow through the distinct segments on the surfaces of the first and second non-conductive substrates to provide a current distribution measurement, said sensor unit including:
