K.C. Neyerlin is a senior scientist at NREL. He is currently involved in R&D activities of polymer electrolyte membrane (PEM) fuel cells. Dr. Neyerlin has over 15 years of experience in PEM fuel cell research and development in industrial, academic, and national lab environments. He has experience in electrode development including the fabrication of both small scale membrane electrode assemblies (MEAs), via ultrasonic spray and electrospinning, and larger scale roll-to-roll production methods. Dr. Neyerlin specializes in the application of in-situ electrochemical diagnostics to elucidate the voltage loss contributions of fundamental electrochemical processes (e.g., electrochemical kinetics of catalysts, ionic and gas phase transport resistances). Dr. Neyerlin currently leads NREL's efforts in both the Fuel Cell Performance and Durability (FC-PAD) and ElectroCat consortia to quantify and improve fundamental electrode performance limitations.
