humidicoreA porous cylindrical wheel coated with desiccant rotates slowly inside the Humidicore housing. This transfers thermal energy from the fuel cell exhaust to the fresh reactant stream. Typically, the Humidicore unit recovers 75-85% of exhaust enthalpy.

While the Humidicore™ is an excellent humidifier, it also serves as the exhaust condenser and the supply blower aftercooler. Emprise now offers the Humidicore™ humidifier in three production sizes for 1.5, 7.5 and 10 kW fuel cell systems. Licensing arrangements are also available.

Humidicore™ Advantages

The Humidicore™ offers several advantages over membrane humidifiers:

  • Higher efficiency in a smaller package
  • Core rotation speed allows fine control of humidification level
  • Lower pressure loss saves blower energy
  • Long life because there are no membranes to dry out and crack
  • Higher allowable inlet temperature eliminates the need for an after cooler in high
  • pressure applications
  • The heat of compression is recovered for use in the turbocharger in high pressure
  • applications
  • The drive motor typically draws less than 30 watts
  • The cartridge concept simplifies initial production and future maintenance.

Please feel free to contact Emprise with any application needs you have. We will be happy to help you select the right Humidicore™ for your fuel cell project!
