A system includes a divider network (71), a memory (48) and a circuit (40, 42, 44). The divider network (71) is adapted to be coupled to fuel cells of a fuel cell stack and provide pairs of signals. Each pair of signals is associated with a different fuel cell and indicates a terminal voltage of the associated cell and another voltage common to the pair of signals. The memory (48) stores indications (50) of different common mode gains, and each common mode gain indication (50) is associated with a different one of the pairs of signals. The circuit (40, 42, 44) is coupled to the memory (48) and adapted to generate an indication of the terminal voltage from each pair based on the associated common mode gain indication (50).
