Gas Diffusion Layer Comparison Chart - 2021

Gas Diffusion Layers (GDL) are one of the components in different types of fuel cells including, but not limited, to Proton Exchange Membrane and Direct Methanol fuel cells. Gas Diffusion Layers serve to provide conductivity in the cell and control the contact between the reactant gases and the catalyst. This layer also aids in managing the water transport out of the membrane. Another essential function of a GDL is to provide a connection between the membrane electrode assembly and graphite plates in the fuel cell stack.

The Fuel Cell Store carries the largest selection of Gas Diffusion Layers in the world! We help you compare all the Gas Diffusion Layers we offer in one simple file so you can narrow down the perfect GDL for your project. With our Gas Diffusion Layer Comparison Table you can compare the specifications of all our carbon papers, carbon cloths, and carbon felts with ease.

What is a Fuel Cell?

Fuel cells are electrochemical devices that convert chemical energy from the reactants directly into electricity and heat. The device consists of an electrolyte layer in contact with a porous anode and cathode on either side. An illustration of a fuel cell with reactant/product gasses and the ion conduction flow directions through the cell is...

Gas Diffusion Layer for Low-Temperature Fuel Cells

The gas diffusion layer is sandwiched between the catalyst layer and the bipolar plates as shown in Figure 1. The gas diffusion layer (GDL) provides electrical contact between electrodes and the bipolar plates and distribute reactants to the electrodes. The GDL also allows the water that is generated as a result of the chemical reaction to move between the electrodes and the ...

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:

The Fuel Cell Electrolyte Layer for Low-Temperature Fuel Cells

The electrolyte layer is essential for a fuel cell to work properly. In low-temperature fuel cells, when the fuel in the fuel cell travels to the catalyst layer, the fuel molecule gets broken into protons (H+) and electrons. The electrons travel to the external circuit to power the load, and the hydrogen proton (ions) travel through the electrolyte until it reaches...

Catalysts for Low Temperature Fuel Cells

The fuel cell electrode is a thin, catalyst layer where electrochemical reactions take place. The electrodes are usually made of a porous mixture of carbon-supported platinum and ionomer. To catalyze reactions, catalyst particles have contact to both protonic and electronic conductors. There also must be passages for...

Low-Temperature Bipolar Plates

Each component of the fuel cell must be designed properly – otherwise, you run the risk of decreasing fuel cell performance. The bipolar plates are termed “bipolar” because they have flow fields on both sides. This design is very convenient when you have membrane electrode assemblies (MEAs) on both sides. In a fuel cell with a...

How to Build a Fuel Cell

The first step in building a fuel cell is to determine the power requirements needed to power the particular device or application. Fuel cells can be used to power anything including phones, laptops, automobiles, buses, houses, businesses and even space shuttles! A single fuel cell can be designed to achieve any current required for a particular application by merely increasing or decreasing the size of the...

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...

Gas Diffusion Layer: Characteristics and Modeling

The gas diffusion layer (GDL) in a fuel cell can consist of a single layer or a double layer (gas diffusion layer and a microporous layer). The GDL is an essential part of the fuel cell because it causes the gases to spread out to maximize the contact surface area with the catalyst...
