Latest Patents

One of Yung-Eun Sung's latest patents focuses on an innovative fuel cell system that incorporates membrane electrode assemblies (MEAs). This system features a polymer electrolyte membrane, a gas diffusion layer (GDL) made of porous metal foam, and a catalyst layer. The inclusion of a metal foam layer significantly improves the efficiency and lifespan of the conventional gas diffusion layer, which consists of both a gas diffusion barrier (GDB) and a microporous layer (MPL). The metal foam GDL ensures consistent maintenance of the appropriate structure and even distribution of pores during operation. Due to the unique mechanical and physical properties of metallic foam, the fuel cell remains unaffected by external physical strain. Among various processing methods for open-cell metal foams, ice-templating stands out as a cost-effective and straightforward processing route suitable for mass production. This method also results in well-aligned and long channel pores, which enhance gas and water flow during the fuel cell's operation.
