Investigation of Filtration Phenomena of Air Pollutants on Cathode Air Filters for PEM Fuel Cells

Filtration of cathode air is one of the challenges in operating proton-exchange membrane (PEM) fuel cells. The poisoning with air contaminants can lead to rapid performance degradation and initiate an aging process of the fuel cell. Various commercially available cathode filters are being tested in...
