2003-11-07, EMPRISE CORPORATION - The Humidicore is a porous cylindrical wheel coated with desiccant rotates slowly inside a cylindrical 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. (PRWEB) 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 (2Mg0•2Al2O3•5SiO2). 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.
