Prof. Detlef Stolten is the Director of the Institute of Energy Research at the Forschungszentrum Julich. Prof Stolten received his doctorate from the University of Technology at Clausthal,Germany. He served many years as a Research Scientist in the laboratories of Robert Bosch and Daimler Benz/Dornier. In 1998 he accepted the position of Director of the Institute of Materials and Process Technology at the Research Center Julich. Two years later he became Professor for Fuel Cell Technology at the University of Technology (RWTH) at Aachen. Prof. Stolten's research focuses on fuel cells, implementing results from research in innovative products, procedures and processes in collaboration with industry, contributing towards bridging the gap between science and technology. His research activities are focused on energy process engineering of SOFC and PEFC systems, i.e. electrochemistry, stack technology, process and systems engineering as well as systems analysis. Prof Stolten represents Germany in the Executive Committee of the IEA Annex Advanced Fuel Cells and is on the advisory board of the journal Fuel Cells. Prof Stolten is the Chair of the World Hydrogen Energy Conference held in May, 2010.
