Abstract: A system and method for estimating an amount of carbon support loss in fuel cells of a fuel cell stack in a vehicle, for example, during vehicle off-times. The system and method include estimating an amount of time that a hydrogen concentration in the fuel cell stack is zero and calculating an amount of carbon loss based on the amount of time that the hydrogen concentration in the fuel cell stack is zero.
