Gas diffusion electrodes (GDEs) are specialized components used in fuel cell systems. They consist of a catalyst layer, a porous gas diffusion layer, and a substrate. GDEs facilitate the electrochemical reactions within a fuel cell by allowing reactant gases (such as hydrogen and oxygen) to diffuse through the porous structure, ensuring efficient contact with the catalyst. This enables the conversion of chemical energy into electrical energy, making GDEs crucial for enhancing fuel cell performance and enabling sustainable power generation. Fuel Cell Etc specializes in providing custom-designed GDEs tailored to meet specific fuel cell requirements, offering superior efficiency and power output.
