Product Description

The 250W Stack Humidifier uses patented planar membrane based technology to humidify and heat the fuel streams going to the fuel cell, by directing the incoming dry gas across one side of a water permeable flat sheet membrane and flowing the hot humidified air stream from the fuel cell exhaust across the other side of the membrane. The membrane transfers the heat and water vapor from the wet stream to the dry stream while preventing the oxygen from crossing over.

The 250W Stack Humidifier consists of a pleated membrane cartridge with plastic injection molded flow-field inserts and housing design for low power (250W) low temperature (70°C) fuel cell applications such as portable power.

Lead Time – 3 Weeks

Cost Effective Design & Manufacturing

•  Low Cost – high volume manufacturing using injection molded components and inexpensive materials
•  Compact – optimized exchanger design
•  Low Maintenance – no moving parts and fewer components
•  Proprietary Advantage – two patents granted and one in application
•  Ease of Serviceability – membrane pleat pack can be easily changed
Outstanding Performance
With over 1000 systems installed with 70 customers in 16 different countries, these Fuel Cell Humidifiers are reliable and proven to supply excellent humidity exchange from the use of its revolutionary polymer membrane and counter flow design.
•  Low Pressure Drop – open channel design using Computation Fluid Dynamics (CFD) modeling
•  Excellent RH Performance – membrane provides high water permeability
•  No Parasitic Losses – humidifier is a passive device, recycling heat and humidity from exhaust
Robust & Versatile
The patented polymer membrane and flexible design of the Humidifier allows the system to endure extreme temperatures and varying pressure conditions.
•  Flexibility – use of alternative membranes based on lifetime and cost requirements
•  Hydrogen Safe – due to low H2 and Air cross-over humidifier can be used on both cathode and anode side
•  Temperature and Pressure Tolerant – able to handle -30 to 80°C in varying pressure systems
Manufacturing & Quality Control
•  Capacity to produce up to 12,000 humidifiers per year
•  Test lab with single cell membrane, full humidifier and longevity testing and analysis capability
•  Quality Management System implemented
•  Computational Fluid Dynamics (CFD) & Finite Element Analysis (FEA) modeling skills
