PEM Fuel Cell Electrocatalysts and Catalyst Layers

Dr Jiujun Zhang is a Senior Research Officer and PEM Catalysis Core Competency Leader at the National Research Council of Canada Institute for Fuel Cell Innovation (NRC-IFCI). Dr Zhang has over twenty-six years of R&D experience in theoretical and applied electrochemistry, including over twelve years of fuel cell R&D (among these six years at Ballard Power Systems and four years at NRC-IFCI), and three years of electrochemical sensor experience. Dr Zhang holds seven adjunct professorships, including one at the University of Waterloo and one at the University of British Columbia. His research is based on: low/non-Pt cathode catalyst development with long-term stability for catalyst cost reduction; preparation of novel material-supported Pt catalysts through ultrasonic spray pyrolysis; catalyst layer/cathode structure; fundamental understanding through first principles theoretical modeling; catalyst layer characterization and electrochemical evaluation; and preparation of cost-effective MEAs for fuel cell testing and evaluation. Dr Zhang has co-authored more than 140 research papers published in refereed journals and holds over ten US patents. He has also produced in excess of seventy industrial technical reports. Dr Zhang is an active member of The Electrochemical Society, the International Society of Electrochemistry, and the American Chemical Society.
