General Details

The Fuel Cell Humidifier for portable, stationary, materials handling and automotive applications.

Perma Pure’s FC Series™ Fuel Cell Humidifiers are the industry standard and offer unparalleled performance, reliability and lifetime up to 20,000 hours.  Designed to meet the exacting requirements of the fuel cell user, these Nafion®-based products provide consistent, repeatable humidification of air and hydrogen across the specified flow range.  Perma Pure Fuel Cell Humidifiers feature a low pressure drop and do not require power to operate, greatly reducing the parasitic load on your system.

FC Series Selection Guide for Fuel Cell Systems

  • FC100 Series – Compact humidifier for portable systems up to 500W. Weighs less than 100 grams. Gas flows to 16 alpm
  • FC125 Series – Built using low-cost molded parts. The FC125-Series humidifiers are an ideal choice for systems up to 1kW. Gas flows to 75 alpm (gas/gas) and 150 alpm (water/gas)
  • FC200 Series – Ideal for systems up to 3kW, the FC200-Series is a rugged, compact humidifier for mobile and stationary applications alike. Gas flows to 300 alpm (gas/gas) and 450 alpm (water/gas)
  • FC300 Series – Our standard humidifier for gas-to-gas humidification in 5kW systems, the FC300-Series is available in ABS or PPO (Noryl) for high pressure applications. Gas flows to 625 alpm (gas/gas) and 2,000 alpm (water/gas)

Maximum differential pressure, with tube > shell side, 5 psig; Max. temperature 90°C. The use of metal fittings is not recommended with FC Series Humidifiers.
Nylon, ABS or polypropylene fittings are suggested.

1 Flow rate recommendations based upon an approach temperature between 4-6 degrees. The optimal dry air inlet temperature range is between 35 and 55°C.

2 Water-to-gas flow rate is based upon a 80-85%RH. See actual performance curves for specific flow rates. Note that the gas pressure must be higher than the water pressure.

3 2″ ports available as option.

4 When ordering, specify port orientation as same side or 180 degree rotation
