Filters Control Cathode Air Contamination

Donaldson Company Inc.’s new filter media is designed for fuel cell cathode air contamination control applications. The patented media removes airborne particulate, as current filters do, and also removes airborne chemicals that negatively affect fuel cell performance.

While airborne chemicals vary, they are generally referred to as volatile organic compounds (VOCs), and can include alpha hydroxy toluene, citrine, mineral spirits, diethylene glycol, terpene alcohol, linear olephinic hydrocarbon, and many other compounds that can negatively affect fuel cell performance. The new media allows fuel cell makers to upgrade existing filters at costs lower than custom-engineered filtration solutions. Its ability to be packaged in various ways allows broad flexibility in filter design and format.

Donaldson fuel cell contamination control (FC3) filters have been protecting fuel cells since 2000, and are now installed on more than 700 fuel cells, from milliwatts to megawatts, in Asia, Europe and North America.
