Assessing durability of cathodes exposed to common air impurities

Data are presented to quantify how common air non-condensable impurities such as NO 2, SO 2, and H 2S show a negative effect on the performance of PEMFCs. The severity of the effects of these impurities varies depending on the impurity, concentration, and dosage but in general the impurities contain...
