Gas Diffusion Layers for Fuel Cells and Electrolyzers
Gas Diffusion Layers are important components in energy conversion devices such as fuel cells and electrolyzers. They allow for efficient gas transport and act as a catalyst support. Our state-of-the-art gas diffusion layers significantly improve the performance and durability of these devices.
Fuel Cells
In fuel cells, our GDLs facilitate the transfer of reactant gases to the catalyst, allowing the chemical reaction to occur. The resulting energy is used to produce electric power and heat.
Electrolyzers
Our Gas Diffusion Layers (GDLs) in electrolyzers act as flow distributors on the cathode-side, ensuring even distribution of reactant gases and efficient water management within the electrolyte. They are durable and highly flexible, enhancing durability and sustained performance over an extended duration, with compression set levels stabilizing after just two cycles.
Redox Flow Batteries
In Redox Flow Batteries our GDL provides large active surface area to allow the flowing-by electrolytes to undergo electrochemical reaction during storage or release of electrical energy.
