A One-Dimensional Heat, Mass and Charge Transfer Model for a Polymer Electrolyte Fuel Cell Stack

A one-dimensional heat, mass and charge transfer model was developed for a polymer electrolyte fuel cell stack to predict the temperatures, mass flows, pressure drops, and charge transport of each fuel cell layer over different operating conditions. The fuel cell layers’ boundaries were...

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:
