A system that is usable with a stack of fuel cells that have cell terminals includes a circuit and scanning units. The circuit provides a selection signal that indicates selection of at least one of the fuel cells for a voltage measurement. The scanning units are coupled to the stack to establish different groups of the fuel cells. Each group is associated with a different one of the scanning units, and each scanning unit has a ground that is referenced to a different one of the cell terminals. Each scanning unit is adapted to, in response to the selection signal, measure and indicate a voltage of each selected fuel cell within the group of fuel cells associated with the scanning unit.
