Pinholes in the membrane electrode assembly (MEA) of a fuel cell can lead to premature fuel cell failure. The main causes for pinhole formation are contaminant particles, non-uniform stress distribution, and membrane corrosion. In this paper fuel cell performance is compared before and after piercin
## Abstract This study focuses on the performances of proton exchange membrane fuel cells (PEMFCs) at 80 and 90 °C with feeds of varying degrees of humidification. The results show that ohmic resistance of the solid electrolyte decreases as the current density is raised because of the back diffusio
