Cathode filter Entaron FC 13

  • The adsorption of critical gases from the cathode air can cause irreversible damage to the catalyst of fuel cells that leads to a loss of performance.
  • The ENTARON FC 13 cathode air cleaner extends the service life of the fuel cell system by reliably protecting the catalyst from these gases.
  • It also protects the system from channel blocking and wear by separating particles from the cathode air.
  • Application for high dust environment.

Key benefits

  • Long life filter system
  • Harmful gases are efficiently removed from the intake air, for example sulfur dioxide (SO2), nitrogen oxides (NOx) and ammonia (NH3)
  • Air flow optimized system for low pressure loss and best air mass flow
  • Flexible design options depending on customer needs
  • Option to integrate further functions like sensors and acoustic measures
  • Compact Housing Concept

Key features

  • Well balanced gas adsorption performance for various gases due to in-house blended activated carbon media
  • Increased adsorption power density utilizing an award-winning wound layer element design
  • Optimized differential pressure while boasting advanced gas removal capacity

Operating parameters

  • Efficiency of more than 80% @0.5 μm (150 m³/h) and more than 98% @ 5.0 μm (150 m³/h)
  • Differential pressure: 2.1 mbar @ 100 m³/h; 5.8 mbar @ 200 m³/h; 10.6 mbar @ 300 m³/h; 16.5 mbar @ 400 m³/h
  • Vertical and horizontal mounting position possible
  • Protection against water
  • Front servicing with comfort fasteners



Application areas

  • Optional use for mobile or stationary fuel cell applications
  • Protection of the cathode air path
