摘要：
A 10-cell Mk 9 stack was characterized using current/voltage mapping during automotive drive cycle testing. Using performance, voltage loss breakdown and CO-stripping data so called degradation "fingerprints" were constructed that provide deeper insights into the underlying degradation modes. Three degradation phases could be distinguished and characterized by the dominant loss type. Localized OCV measurements are shown to provide useful information about crossover leak formation and location.
