A vehicle system includes a voltage sensing circuit configured to detect voltages across cells in a fuel cell stack, and powered by a power supply sharing a voltage reference with the cells and having a voltage magnitude greater than a sum of voltage magnitudes of the cells. The system further includes a controller configured to, responsive to a change in polarity in at least one of the voltages indicative of freezing of the cells, issue an alert notification.
