Dr. André Weber

Dr. André Weber is a senior researcher (Akademischer Oberrat) at the Institute for Applied Materials (IAM-WET) at Karlsruhe Institute of Technology (KIT), Germany, where he heads both the fuel cell and battery research groups. In addition, he acts as scientific manager of the “Fuel Cell Test Laboratory“ since 2002, a joint lab of KIT and the European Institute for Energy Research (EIfER), designated for the testing of fuel cell systems.

After studying electrical engineering at RWTH Aachen university and a stay at Siemens Central Research, Munich (Germany), where he became acquainted with Ellen Ivers-Tiffée, he obtained his PhD at Universität Karlsruhe (TH), now KIT, in 2002. During this time he was strongly involved in the establishment of the SOFC group at IAM-WET. He has collaborated with many groups in numerous national, European and international research projects since 2000.

His research is related to the electrical testing and modeling of fuel cells and batteries, with a special emphasis on the detailed characterization by means of electrochemical impedance spectroscopy. The experimental and theoretical work of his research groups ranges from fundamental studies on model systems to the analysis of commercial products, aiming at an understanding of the complex coupling of electrochemical reactions and transport mechanisms in electrochemical devices.

André Weber has authored or co-authored several book chapters, 80 conference proceedings and more than 100 peer-reviewed journal papers on scientific topics related to fuel cells and batteries.

Dr. Dino Klotz

Dr. Dino Klotz is a postdoctoral research associate at the International Institute for Carbon Neutral Energy Research (I2CNER) at Kyushu University, Fukuoka, Japan.

He obtained his PhD in 2012 at KIT, in the group of Ellen Ivers-Tiffée, where he was an active member of the SOFC group, mostly dealing with impedance measurements, modeling and analysis.

From 2013 to 2015, he was a post-doc in Prof. Shikazono's group at the University of Tokyo, where he analysed composite cathodes for SOFCs. After that, he joined Prof. Rothschild's group at the Technion in Haifa, Israel, where he established new photoelectrochemical impedance techniques and analysis methods on hematite photoanodes for solar water splitting. He recently returned to SOFC research at I2CNER, where he applies optical impedance techniques to probe the surface exchange process on model thin film cathodes. This work is in collaboration with Prof. Tuller's group at the MIT in Boston.

Dino Klotz has authored more than 40 publications with a strong focus on impedance measurement, analysis and modeling. He has been a tutorial instructor for the EIS tutorials at the MRS fall meeting 2016 and SSI conference in 2017.
