Based on performance or composition specifications, HYNOLOGY formulates anodic and cathodic catalytic inks from catalysts, ionomer suspension or solution, solvents and additives, and coats them on a proton exchange membrane (PEM) to form CCMs (Catalyst Coated Membrane). This process can be direct or indirect, with an extra step to transfer the coating from the intermediate (inert) support to the final support. This process, currently carried out on R&D equipment, is currently being industrialized, with a view to setting up a roll-to-roll production line.
Based on performance or composition specifications, HYNOLOGY formulates anodic and cathodic catalytic inks from catalysts, ionomer suspension or solution, solvents and additives, and coats them on a diffusion layer (GDL) to form a GDE (Gas Diffusion Electrode).

From detailed plans provided, CCM (Catalyst Coated membrane) are assembled with diffusion layers and "subgaskets" to form a final assembly (MEA) ready to be integrated into a fuel cell stack, electrolyzer or electrochemical compressor. The same process can be carried out from GDE (Gas Diffusion Electrode), polymer electrolyte membrane and subgasket to result in the production of MEAs for fuel cells or electrolyzers.
