Membrane Electrode Assembly (MEA) Activation Procedures
Why is an activation procedure or break-in necessary for a membrane electrode assembly (MEA)? A large reason for performing an activation procedure or break-in is to properly humidify the membrane portion of the MEA that was dried ...

What is the Difference Between Carbon Paper and Carbon Cloth Based Gas Diffusion Layers (GDL)?
Carbon Paper Gas Diffusion Layers Carbon Paper Gas Diffusion Layers (GDL) (e.g. Sigracet, Freudenberg, Toray, etc) tend to be thinner and more brittle than Carbon Cloth Gas Diffusion Layers (e.g. ELAT™, GDL-CT). ...

What is the Purpose of a Gas Diffusion Layer (GDL)?
The Gas Diffusion Layer (GDL) plays several critical roles in a typical fuel cell application and is often integrated as part of the Membrane Electrode Assembly (MEA). Typical applications that use GDLs consist of Polymer ...

What Hydrogen Storage is Best for Me?
There are a number of different Hydrogen storage options available. The one which is best for you depends on what is most important for your application: Compressed Economical Readily Available Metal Hydride (MH) High volumetric ...

ELAT-1400 Gas Diffusion Layer (GDL) Not “Discontinued”
After the original manufacturer of ELAT Gas Diffusion Layer (GDL) stopped producing the material, many of the fuel cell industry had to scramble for replacements and were continuing their projects based on inventory already purchased. We were ...

Why is Humidity / Moisture Control Important in a Fuel Cell?
The root of all of this is that Nafion membranes must stay hydrated to function properly. If they are not fully humidified the conductivity decreases and therefore more of the electricity is converted directly to heat before it leaves the ...

Fuel Cell Voltage Monitoring Considerations
Knowing what’s happening inside a fuel cell is a critical function, especially as fuel cells are continuing to be developed. One important aspect of this is to measure the voltageof each cell in a stack. Although this may sound trivial, ...

How Many Cells do I Need in my Fuel Cell? (Simple Fuel Cell Design Guide)
As with Electrolyzers on my previous post, there are many nuances in the optimal design of a Fuel Cell. The proper selection depends on the application, type of fuel cell, component selection and design (MEAs, flow fields, etc.) and a ...

FuelCellsEtc – Spin-out or Sale response
There has been some question about whether FuelCellsEtc was a “Spin-out” or an “Acquisition” (see Fuel Cell Nations post). I confess, this is largely due to my own inconsistencies in terminology. So ...
