Humidity Control in Manufacturing

Torrington, CT

FuelCell Energy is a leading manufacturer of fuel cell systems that provides clean, green energy. Their systems provide power, carbon capture, energy storage and hydrogen production. They help their clients achieve a net-zero energy profile.

Accuspec has provided 6 DX Hybrid Desiccant Systems for FuelCell Energy’s manufacturing facility over the past 18 years. The proper manufacturing of fuel cells relies on precisely controlled low humidity levels for the fuel cell’s proton exchange membrane (PEM).

Our hybrid desiccant systems deliver humidity control throughout the fabrication process, including the slurry prep for the membrane, the slurry application on the PEM, electrode layer creation, membrane electrode assembly and the final fuel cell assembly. Without proper humidity control during manufacturing, the fuel cell will not achieve optimal performance, and its service life will be shortened.

Project Highlights

  • DH units utilize the condenser heat from the DX precool coil to reactivate the desiccant wheel.
  • Provides outstanding humidity control of 100% OA with achieving dewpoints of 45°F or lower year-round.
  • Avoids the energy-intensive method of subcooling and then reheating the air stream.
  • DH units provide one of the industry’s highest moisture removal efficiencies (MREs).
