Patrick Moseley PhD DSc graduated from the University of Durham, England. He worked for 23 years at the UK Atomic Energy Research Establishment at Harwell, where he brought a background of crystal structure and materials chemistry to the study of lead-acid and other types of battery, thus supplementing the traditional electrochemical emphasis of the subject, and to the study of sensor materials. From1995, Pat was Manager of Electrochemistry at the International Lead Zinc Research Organization in North Carolina, USA, and Program Manager of the Advanced Lead-Acid Battery Consortium. In 2005 he became President of the Consortium. He is also a director of Atmospheric Sensors Ltd. Pat has been an Editor of the Journal of Power Sources since 1989 and, together with David Rand, was a Co-editor of the Encyclopaedia of Electrochemical Power Sources published by Elsevier in 2009. In 2008, he was awarded the Gaston Plant Medal by the Bulgarian Academy of Sciences David Rand AM PhD ScD FTSE was educated as an electrochemist at the University of Cambridge. Shortly after graduating in 1969, he emigrated to Australia and has spent his research career working at the government's CSIRO laboratories in Melbourne. In the late 1970s, David established the CSIRO Battery Research Group and remained its leader until 2003. As a Chief Research Scientist, he was CSIRO's scientific advisor on hydrogen and renewable energy until his retirement in 2008. He has served as the Vice-President of the Australian Association for Hydrogen Energy. David has been the Asia-Pacific Editor of the Journal of Power Sources since 1983, and the Chief Energy Scientist of the World Solar Challenge since 1987. He was elected a Fellow of the Australian Academy of Technological Sciences and Engineering in 1998, and received the Order of Australia in 2013 for service to science and technological development in the field of energy storage. J rgen Garche graduated in chemistry at the Dresden University of Technology (DTU) in Germany. He was awarded his PhD in theoretical electrochemistry and his habilitation in applied electrochemistry from the same university. He worked at the DTU in the Electrochemical Power Sources Group for many years in different projects, mainly in conventional batteries, before he moved to the Centre for Solar Energy and Hydrogen Research in Ulm, where he was, until 2004, the Head of the Electrochemical Energy Storage and Energy Conversion Division. He was Professor of Electrochemistry at Ulm University and Guest Professor at Shandong University (China). He has published more than 300 papers, 10 patents, and 2 books. He is a member of the Scientific Board of the European Fuel Cells and Hydrogen Joint Undertaking. Furthermore he is a member of the editorial board of 5 scientific battery and fuel cell journals. J rgen's research has been recognized by the award of the European FC-Award "Schoenbein Medal (2003).
