The "HUMIDICORE" Fuel Cell Humidification System revolutionizes Fuel Cell design!
November 5 2003--How does the Humidicore work? As warm, humid exhaust air enters the Humidicore from the Fuel Cell, the rotating Cordierite drum adsorbs the exhaust water vapor and transfers it to the incoming cool, dry inlet stream. The characteristics of the desiccant coated drum allow only the water vapor to be transferred, while the spent gases continue out of the system. The water vapor never condenses; therefore, no external energy is required to move it back into vapor form. The Humidicore drum uses face seals to separate the incoming stream from the exhaust.
Benefits include:
Replacing aftercoolers, condensers and humidifiers
Runs on waste heat
Commercially available components
Inexpensive
Lightweight
The Humidicore uses a ceramic honeycomb material with a dominate chemical composition of Cordierite (2Mg02Al2O35SiO2). Properties include low pressure drop, high structural strength, dimensional stability, long life and chemical inertness.
The unique properties of the cordierite allow the construction of a simple, inexpensive and almost indestructible enthalpy wheel. The rotor is a unitary cylinder of Cordierite in a honeycomb matrix. The contact type end seals act directly against the honeycomb to form very efficient labyrinth seals. The very low thermal expansion rate of Cordierite greatly simplifies the sealing system by minimizing axial growth during operation. It's currently being mass produced and is most commonly used in automotive catalytic converters costing as little as 30 cents per cubic inch.
Emprise currently offers production models of the Humidicore in three different models designed to work with a 3kW, 10kW and 20kW fuel cell. Physical sizes and performance maps are available at http://www.humidicore.com.
