Membrane Electrode Assembly: MEA (5-layer) |
|
NEWS |
| |
The membrane electrode assembly, MEA, is the heart of a fuel cell. |
|
|
| |
It consists of the ion-exchange membrane, anode and cathode electrodes, |
|
|
| |
and the gas diffusion layers. Creating electricity by combining |
|
|
| |
hydrogen and oxygen taken from the air, Proton Exchange Membrane |
|
|
|
fuel cells require catalyst and diffusion media applied to a membrane |
|
|
|
that is then layered between two conductive plates. This layered product is the Membrane Electrode Assembly (MEA). |
|
product is the Membrane Electrode Assembly (MEA). Fuel Cell Scientific currently offers 5 layer MEAs. Five-layer MEAs are
|
|
|
|
|
|
comprised of a membrane and anode and cathode catalyst electrodes bonded to two gas diffusion media. Options in MEA |
|
design include but are not limited to: size of active area and/or membrane, gas diffusion media, catalyst., and shape. |
|
Fuel Cell Scientific’s Membrane Electrode Assemblies are intended to provide consistent performance. |
|
Our standard MEA uses Pt on Vulcan XC-72 Carbon catalyst utilizing hydrophobic carbon paper as a backing layer |
|
with 1mg Pt/cm² loading hot-pressed onto a Nafion™ 115 ion exchange membrane. Please inquire about custom MEAs. |
