个人简介

Prof. Narayan received his Ph. D in electrochemistry from the Indian Institute of Science, Bangalore and a Masters in Chemistry from the Indian Institute of Technology, Madras (Chennai). He was a post-doctoral fellow at the University of Exeter, UK and also was awarded the Resident Research Associateship of the National Research Council to work at the Jet Propulsion Laboratory. During his 20 years at NASA's Jet Propulsion Laboratory (JPL) he led the fuel cell research activities for over 15 years and also headed the Electrochemical Technologies Group for 7 years. He has worked successfully with various government and private funding agencies to make advances in both fundamental and applied aspects of electrochemical power sources. While at JPL, Dr. Narayan and his associates pioneered the development of direct methanol fuel cell power sources for military and commercial applications, developed new approaches to catalyst preparation by the sputter-deposition technique, new membranes and stacks, and demonstrated a range of hybrid power source systems for space and defense application. He received NASA-JPL's Exceptional Achievement Award for the development of direct methanol fuel cell and transferring the technology to industry. He has over 35 journal publications and 40 US Patents on various aspects of electrochemical technology. He has delivered invited talks on numerous occasions and has organized several conferences under the auspices of the Electrochemical Society. From 2009-2011 he was the Chairman of the Energy Technology Division of the Electrochemical Society of USA. He has active collaborations with NASA, DoE's National Laboratories, and Industry. Prof. Narayan joined the faculty of the Department of Chemistry, Loker Hydrocarbon Research Institute in May 2010 to advance electrochemical power sources research.

研究领域

Electrochemistry

Prof. Narayan's research focuses on the fundamental and applied aspects of electrochemical energy conversion and storage to reduce the carbon footprint of energy use and by providing energy alternatives to fossil fuel. To this end, group focuses on three major topics: Large-scale energy storage in batteries to enable renewable energy generation Developing advanced materials and systems to enable commercialization of high-energy density fuel cell and battery technologies Converting carbon dioxide and sunlight to liquid fuel by electrochemical routes
