摘要： An integrated cell voltage unit for monitoring the voltage of each fuel cell in a fuel cell stack that is easily and reliably electrically coupled to the bipolar plates of the fuel cell stack. The bipolar plates of the fuel cell stack are equipped with a specialized tab connector that engages with a corresponding electrical connector on the cell voltage unit. Either the tab connectors on the bipolar plates or the corresponding connectors on the cell voltage unit include flexible members to provide a suitable electrical friction engagement. The cell voltage unit is attached to the bipolar plates and does not require its own separate housing. In one embodiment, the housing of the fuel cell stack includes a recessed portion in which the cell voltage unit is positioned.
