Seong Jin An

Energy Conversion and Storage


Supervising Faculty: David Wood

Seong Jin has had PEM fuel cell research experience since 1999, with his longest positions being at Samsung and GS Fuel Cell (GS-Caltex). His prior fuel cell projects have included membrane electrode assemblies (MEAs) (evaluation, water management, durability, diagnosis, etc.), stack development and evaluation, fuel cell system development, steam reformer optimization, preferential oxidation reactor development, and more. His current research interest is energy storage and conversion, especially high energy Li-ion battery electrodes and PEM fuel cell MEAs. Outside of research, he likes basketball, swimming, snowboarding, and movies.
