Varcoe, John - University of Surrey - Department of Chemistry

个人简介

Prof John Varcoe trained at the University of Exeter, receiving a B.Sc.(1995 - top 1st class honours) and Ph.D. (1999). He has held post-doctoral positions at the University of Surrey (1999-2006). He was appointed Lecturer in Materials Chemistry at the University of Surrey in August 2006, Reader in Materials Chemistry in April 2011 and Professor of Materials Chemistry in April 2013. He obtained his Postgraduate Certificate in Academic Practice in 2008. He was Faculty Researcher of the Year in 2010 and was awarded an EPSRC Leadership Fellowship (2010-2015).

研究领域

His research interests are the development of polymer electrolytes, ionomers, and catalysts for fuel cells, alkaline water electrolysers, redox flow batteries, and reverse electrodialysis systems. More specific interests include the use of alkaline anion-exchange membranes (AAEM) and ionomers (AEI) in electrochemical energy technologies, the interface between polymer electrolytes and catalysts, and the use of hydrogen from ammonia cracking in fuel cells. An additional theme being pursued is the study of low temperature carbonate/bicarbonate conducting polymer electrolytes.
