Gas Diffusion Layer Comparison Chart - 2023

Gas Diffusion Layers (GDLs) 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.

What is the Difference Between Carbon Paper and Carbon Cloth Gas Diffusion Layers?
Carbon Paper Gas Diffusion Layers Carbon Paper Gas Diffusion Layers (GDLs) (e.g. Sigracet, Freudenberg, Toray, etc) tend to be thinner and more brittle than Carbon Cloth Gas Diffusion Layers (e.g. ELAT™, AvCarb , CT Carbon Cloth with MPL, etc.). Each variation has different mass transport, porosity, hydrophobicity and conductivity, among other things. Every manufacturer releases their own technical data sheet, so trying to parse all the information and find like qualities can be quite time-consuming and difficult. We have broken down the information into an easily digestible ..
Membrane Comparison Chart - 2024
For PEM fuel cell and electrolyzer applications, a proton exchange membrane is sandwiched between an anode electrode and a cathode electrode. During electrochemical reaction, oxidation reaction at the anode generates protons and electrons; reduction reaction at the cathode combines protons and electrons with oxidants to generate water. To complete the electrochemical reaction, the proton exchange membrane plays a critical role that conducts protons from anode to cathode through the membrane. The proton exchange membrane also performs as a separator for separating anode and cathode reactants..
