Abstract
An embedded measurement circuit for a fuel cell stack. The fuel cell stack includes a plurality of bipolar plates that include recessed areas providing conduction and retention points for the measurement circuit. The measurement circuit has a length, a width and a thickness where the width and length of the circuit are greater than the thickness of the circuit. The measurement circuit includes a stepped cut-out portion defining steps along an edge of the length of the circuit. The measurement circuit is positioned between and among the plurality of bipolar plates so that each one of the steps of the stepped cut-out portion of the measurement circuit enables electrical contact with a separate plate and the width of the circuit is perpendicular to a plane of the plates and the thickness of the circuit is along the plane of the bipolar plates.
