Hydrogen crossover rate are measured for perforated MEAs. The higher hydrogen crossover rate are detected for perforated MEAs. The effect of the location of pinhole on performance is analyzed. The effect of the location of pinhole on hydrogen crossover is analyzed. Blemish near gas inlet and outlet have more influence over durability.
