Latest Patents

Soonwook Hong holds a patent for a process titled "Scalable roll-to-roll fabrication of high-performance membrane electrode assemblies." This manufacturing process involves several key steps. It includes depositing a first catalyst on a first gas diffusion layer (GDL) to create a first catalyst-coated GDL. Following this, a first ionomer is deposited on the first catalyst-coated GDL to form a first gas diffusion electrode (GDE). The process continues with the deposition of a second catalyst on a second GDL, followed by the application of a second ionomer on the second catalyst-coated GDL to create a second GDE. Finally, the first GDE is laminated with the second GDE and an electrolyte membrane positioned between them to form a membrane electrode assembly (MEA). The MEA consists of a first GDL, a second GDL, an electrolyte membrane situated between the two GDLs, a first catalyst layer between the first GDL and the electrolyte membrane, and a second catalyst layer between the second GDL and the electrolyte membrane. Notably, the thickness of the electrolyte membrane is about 15 micrometers or less.
