Short Course #3
Polymer Electrolyte Fuel Cells
Hubert Gasteiger and Thomas J. Schmidt, Instructors
Please visit the PRiME meeting page for registration information. Early-Bird Registration rates are in effect until September 7, 2012. See a list of all Short courses offered at the Hawaii meeting.
This short-course develops the fundamental thermodynamics and electrocatalytic processes critical to polymer electrolyte fuel cells (PEFCs including Direct Methanol and Alkaline Membrane FCs). In the first part, we will discuss the relevant half-cell reactions, their thermodynamic driving forces, and their mathematical foundations in electrocatalysis theory (e.g., Butler-Volmer equations). Subsequently, this theoretical framework will be applied to catalyst characterization and the evaluation of kinetic parameters like activation energies, exchange current densities, reaction orders, etc.
In the second part of the course, we will illuminate the different functional requirements of actual PEFC (incl. DMFC and AMFC) components and present basic in-situ diagnostics (Pt surface area, shorting, H2 crossover, electronic resistance, etc.). This will be used to develop an in-depth understanding of the various voltage loss terms that constitute a polarization curve. Finally, we will apply this learning to describe the principles of fuel cell catalyst activity measurements, the impact of uncontrolled-operation events (e.g., cell reversal), and the various effects of long-term materials degradation.
To benefit most effectively from this course, registrants should have completed at least their first two years of a bachelor’s program in physics, chemistry, or engineering; or have several years of experience with PEFCs.
About the Instructors
Hubert A. Gasteiger received his MS in chemical engineering from Oregon State University in 1988, and his PhD in chemical engineering from UC Berkeley in 1993 (with Elton Cairns). After post-doctoral positions at the Lawrence Berkeley Laboratory with Phil Ross and Nenad Markovic and at Ulm University (with Jürgen Behm), he joined GM/Opel’s Fuel Cell Activities program (Honeoye Falls, NY, USA) as Technical Manager for PEM fuel cell materials development (1998-2008), where he was promoted to GM Technical Fellow (2004). Subsequently, he worked for one year as Director of Catalyst Technologies at Acta S.p.A. (Italy). In 2009 he was appointed Visiting Professor at MIT in the group of Yang Shao-Horn, working on lithium-air batteries and fuel cell electrocatalysis. Since 2010 he is Full Professor at the Technische Universität München, focusing on materials and electrode development for batteries and fuel cells.
He co-authored 75 peer-reviewed publications, 14 book chapters, and 31 patents/patent applications. He also served as Editor-In-Chief for Wiley’s Handbook of Fuel Cells (vols. 1 4 in 2003 & vols. 5&6 in 2009) and currently leads the ECS Fuel Cell Subcommittee. In 2004, he received the Klaus-Jürgen Vetter Award from the International Society of Electrochemistry, became a Fellow of the ECS in 2011, and received the Grove Medal for fuel cell research in 2012.
Thomas J. Schmidt received his University Diploma (1996) and his PhD (2000) in Chemistry from the University of Ulm (Germany, with Jürgen Behm), before he joined the group of P.N. Ross and Nenad Markovic at the Lawrence Berkeley National Laboratory. He continued to work with G.G. Scherer at Paul Scherrer Institut’s Electrochemistry Laboratory in Villigen/Switzerland. Since fall 2002, he was working in the industrial development of high temperature membrane electrode assemblies and its components. During these eight years in industries, Dr. Schmidt led the high-temperature MEA R&D activities as Director R&D and helped to successfully commercialize the BASF Fuel Cell Celtec® MEAs. In parallel in 2009 and 2010, he has been working as Lecturer for Physical Chemistry at Provadis School of International Management and Technology, University of Applied Sciences in Frankfurt/Germany.
In February 2011, Dr. Schmidt became Full Professor at the Swiss Federal Institute of Technology in Zurich (ETH Zurich) and, in paralell also holds the position as Head of the Electrochemistry Laboratory at Paul Scherrer Institute, Villigen, Switzerland.
