NuVant Systems has released ELAT™ LT-1400 Gas Diffusion Layer (GDL) back on to the market at a fraction of the cost while naming FuelCellsEtc as their sole distributor. The new price of ELAT is expected to make the product far more suitable in cost sensitive applications than it has ever been in the past. FuelCellsEtc will also be providing value added services of manufacturing catalyzed Electrodes (gas diffusion electrodes) and Membrane Electrode Assemblies (MEA) using ELAT.
ELAT is a woven carbon cloth GDL with a carbon microporous layer. It has been engineered to have state-of-the-art performance over a wide range of operating conditions and plays a critical role in the efficiency of fuel cells. ELAT’s suggested uses include fuel cells, electrolysis, flow through batteries, water clean-up electrochemistry and more.
Daniel Westerheim, CEO of FuelCellsEtc states, “We are very excited to not only see ELAT back on the market but to be able to offer our customers another option for a high quality gas diffusion layer. ELAT also helps maintain our goal of providing the right MEA and GDE configuration for each customer and application.”
A fuel cell is a device that generates electricity by a chemical reaction from two electrodes (an anode and cathode) and an electrolyte; it uses a chemical reaction to produce electricity much like a battery, but unlike a battery, a fuel cell never runs out of “juice” and never needs to be recharged so long as it has a constant supply of hydrogen and oxygen.
The Gas Diffusion Layer (GDL) is located between the gas flow channels and the catalyst/ PEM layer. The GDL’s purpose is two-fold: 1) it allows gas to diffuse from Gas Flow Channel to the Catalyst and 2) allows water to flow away from the catalyst. This is a very critical role: too little water will result in high membrane resistivity and too much water “floods” the fuel cell, preventing efficient gas flow to the catalyst.
Below are the specifications for the ELAT LT 1400W gas diffusion layer:
|Property||Unit of Measure||Unit|
|Electrical Conductivity (bulk)||Ωcm||~0.002|
|Carbon Content||%||99.5 in woven, variable in coating for hydrophobicity|
|Web Material||N/A||Woven on carbon fiber|
