Air/noise filtration system

FC3 airborne contaminant and noise-filtration systems are designed for fuelcell systems. In addition to shielding systems from contaminants that cut fuelcell life, such as micrometer-sized particles, salts, oils, chemicals, and volatile organic compounds, which are all found in varying degrees in the atmosphere, FC3 cathode filtration uses noise control to quiet sound from fuel-cell compressors and fans.
