Membrane Electrode Assembly (MEA) Characterization

Selecting the appropriate technique to properly characterize the fuel cell is extremely important because it helps the user to understand why the fuel cell is performing well or poorly. These techniques will help discriminate between activation, ohmic and concentration losses, fuel crossover, and...

Low-Temperature Fuel Cell Membrane Electrode Assembly Processing Techniques

The fuel cell stack consists of many layers, including: The Membrane Electrode Assembly (MEA), Gaskets, Flow field plates, and End plates.  There are two standard methods of assembling the membrane electrode assembly (MEA) in low-temperature fuel cells. The catalyst layer can be applied in one or two steps. For the first method, there are five common ways to prepare and apply the catalyst for the GDL/catalyst assembly:
