Fuel cell technologies have seen extraordinary advances over more than two decades. However, two challenges still facing these technologies, the oxygen cathode and liquid fuels anodes. The oxygen (air) cathode has steadily posed a challenge for fuel cell research regardless of the fuel being used. This is particularly the case for acid media such as for the proton exchange membrane fuel cell (PEMFC), direct methanol fuel cell (DMFC) and formic acid fuel cell (FAFC). The main issues with the air cathode include high loading of platinum group metal (PGM) catalysts, sluggish kinetics, triple-phase boundary requirements, cathode depolarization from fuel crossover and flooding. Substituting the air cathode with a redox couple cathode (i.e. Fe2+/Fe3+-carbon) was demonstrated to be a practical approach to address many of the above-stated challenges with an air cathode particularly for applications that are not limited by the size of the energy conversion system. The redox-based cathode has been demonstrated for different fuels and has shown to allow for more cell design flexibility and a significant reduction in the fuel crossover issue.

About the Speaker

Khalid Fatih is a senior research officer, a team leader and project manager at the National Research Council Canada since 2002. He received his Ph.D. degree in chemistry from Université De Sherbrooke (Sherbrooke, Quebec, Canada) in 2001 in the area of electrocatalysis. He was a postdoctoral research fellow at Acadia University (Wolfville, Nova Scotia, 2001-2002) working in the area of bio-electrochemistry.

Dr. Fatih expertise is in polymer electrolyte fuel cells, electrocatalysis, surface electrochemistry, electrode kinetics and batteries. His current interests include various fundamental and applied aspects of lithium-ion batteries, flow batteries and electrolytic hydrogen production. He is leading projects to assess the state of health and develop diagnostic tools for batteries as well as assessing risks regarding battery transportation. Dr. Fatih is currently the chair of the Canadian Sub Committee-CSC/IEC-SC21A on Secondary cells and batteries. He is also a member of the Canadian delegation to UN-Informal Working Group on Electric Vehicle Safety for Global Technical Regulation (EVS-GTR). To his credit, Dr. Fatih authored and co-authored over 100 scientific contributions including refereed journal articles, technical reports, proceedings, patent applications and conference presentations.
