Start-stop degradation operation

Electrode Degradation During Start/Stop Operation... [Pg.231]

The preceding section presented an analysis of certain degradation factors (start-stop operation, load cycling, idling, and impurity contamination) specific to automotive fuel cells and discussed possible solutions. The following degradation factors are especially important for improving MEA durability ... [Pg.450]

Premature operation Performance degradation Failed to perform within given limit Performed undesired function Failed to operate in time Wrong timing in sequential operation Intermittent operation Failed to start or stop in proper time Loss of output Degraded output Lower operational capability This list is necessary for critical analysis to determine failure mode probability, as discussed earlier.
