NOVELTY - An electric signal processing system comprises fuel cells; bipolar plates (22, 24, 26 and 28) including plate contactor (30, 32, 34, and 36), and at least two of the bipolar plates include connector depression; conductive compressible connectors (40) electrically coupled to the bipolar plates at either the plate contactor/connector depression; and at least one circuit board (44) electrically coupled to the compressible connector. The circuit board processes the electric signals from the bipolar plates which are in electrical communication with the compressible connector.    USE - As an electric signal processing system for a fuel cell stack (claimed).    ADVANTAGE - The system allows the processing of the electric signals of every cell using fewer electrical components, thus reducing the amount of space required and the costs associated with it.    DETAILED DESCRIPTION - An electric signal processing system for a fuel cell stack comprises fuel cells; bipolar plates (22, 24, 26 and 28) each including plate contactor (30, 32, 34, and 36) and at least two of the bipolar plates including a connector depression; at least one conductive compressible connector (40) electrically coupled to the bipolar plates at either the plate contactor or the connector depression; and at least one circuit board (44) electrically coupled to the conductive compressible connector. The circuit board processes the electric signals from the bipolar plates which are in electrical communication with the conductive compressible connector. The conductive compressible connector is an elastomer having conductive wires, laminates of alternating conductive and/or non-conductive elastomers. The system further comprises a trace connector between and in electrical communication with the conductive compressible connector and the circuit board, where the trace connector enables the circuit board to process the electric signal from the bipolar plates; and an electronics package electrically coupled to the circuit board, where the electronics package processes the electric signals. The trace connector is a flexible circuit substrate or a rigid circuit board substrate. The connector depression is electrically coupled to the conductive compressible connector directly below and in contact with the bottom side of the connector depression. The electronics package includes a power conversion module, a power distribution module, and communication devices.
