DIFFUSIONFUEL cellsFUEL cell efficiencyGAS analysisA proton exchange membrane fuel cell is an energy convertor that produces environmentally friendly electrical energy by oxidation of hydrogen, with water and heat being byproducts. This study investigates the gas diffusion layer (GDL)...
Gas Diffusion Layer (GDL) was optimized to maximize the performance of a Proton Exchange Membrane Fuel Cell (PEMFC) using design of experiments (DoE). The fabrication of the GDLs consisted of using a non-woven carbon paper substrate, coated with a mixture (slurry) of Pureblack Carbon (PB)...
PROBLEM TO BE SOLVED: To form a membrane electrode assembly (MEGA) with a microporous layer (MPL) enhancing flooding resistance while ensuring sufficient gas diffusion, and to provide a technique uniformizing the reaction inside the electrode surface. SOLUTION: A gas diffusion layer (GDL) applied ...
5.2Gas Diffusion Layer Generally, agas diffusionlayer consists of carbon cloth or carbon paper, which is fabricated from carbon fiber, for example, Toray®and SGL®, etc. GDL, with 100–300μm thickness, collects current as well as transports reactants and products. GDL also serves as a...
For example, they are widely used as electrodes in batteries [1], gas diffusion layer (GDL) [4–6] or flow-field [7,8] in electrolysers, fuel cells and unitised regenerative fuel cells (URFCs). They can be either in the form of metal foams, sintered metallic powders/fibres or mesh...
