Abstract
PEM Fuel Cell Durability for Vehicular Applications: Degradation Modes and Mechanisms

Durability is one of the most significant technical barriers to the practical applications of PEM fuel cells for vehicular applications; the variations in the load demand of vehicles during operation, or the various driving cycles, significantly reduce the durability of PEM fuel cells. Therefore, understanding the mechanisms of degradation modes for different fuel cell components is of importance to the development of high-performing durable low-cost PEM fuel cells. In this talk, the various modes of fuel cell component degradation (or aging) will be described, and the mechanisms of the degradation modes will be elucidated. The effect of design and operating conditions will be prescribed. Since the component degradation rate depends on the driving cycles of the vehicle, and the differences in road conditions/designs leading to the different “standard” driving cycles in North America, Europe and Japan complicates the design of PEM fuel cells for vehicles destined to the different markets of the world.
Dr. Xianguo Li is a Professor of Mechanical and Mechatronics Engineering, and a University Research Chair, at the University of Waterloo. He received his Bachelor of Engineering degree from Tianjin University, China, in 1982, Masters and PhD degree from Northwestern University, Evanston, Illinois, USA, in 1986 and 1989, respectively.

Presentation title - “An Overview of Electrochemical Hydrogen Adsorption and Absorption”

Abstract
An Overview of Electrochemical Hydrogen Adsorption and Absorption
Gregory Jerkiewicz
Department of Chemistry, Queen’s University Kingston, ON. K7L 3N6, Canada
The need for renewable and carbon-free energy sources drives interest in hydrogen as an energy source and carrier, which is the most important element of the emerging hydrogen economy. This overview presentation focuses on the atomic-level understanding of the fundamental steps of the electro-adsorption (electrochemical adsorption) of hydrogen (H) on transition-metal electrodes. It presents basic events of the physisorption and chemisorption of H under gas- phase, as well as the electro-adsorption of H under electrochemical conditions, with the objective of identifying characteristics that are unique to the gas-phase and the electrochemical environments. The electrochemical environment, which typically comprises a solid transition- metal electrode, an aqueous electrolyte solution, and an electrostatic field, creates favourable conditions for the electro-adsorption of two different H species, namely the under-potential and over-potential deposited H (HUPD and HOPD). The electro-adsorptions of HUPD and HOPD occur within two distinctive potential ranges and, consequently, the associated thermodynamic state functions of the processes (Dec-adsGo, Dec-adsHo, (Dec-adsSo) as well as the surface bond energies (EM–Hec-ads) and surface adsorption sites are different. While the electro-adsorption of HOPD takes place on all metallic and non-metallic materials on which molecular hydrogen gas, H2(g), can be generated electrochemically, the electro-adsorption of HUPD is observed only in the case of the platinum (Pt) group metals (PGM, e.g., Pt, Rh, Pd) and the species does not take part in the H2(g) generation. Consequently, it is a unique property of PGM’s. The existing spectroscopy results, although limited and inconclusive, support the concept of two distinct electro-adsorbed H species (HUPD and HOPD). However, they also call for additional and dedicated research. The processes can also be studied and elucidated using the electrochemical quartz crystal nano-balance (EQCN) technique, and our recent investigations led to the discovery of the potential of minimum mass (Epmm) for Pt electrodes. The HUPD species modifies the interfacial hydrophilic-hydrophobic properties of Pt making it hydrophobic-like and, consequently, minimizes the interactions between the Pt surface and the electrolyte components. The Epmm property together with other physical and chemical properties of Pt (noble character, chemical stability, electronic structure) further confirm why Pt is the best transition metal for electrochemical reactions involving H, such as the hydrogen evolution reaction (HER), the hydrogen oxidation reaction (HOR), and the electrocatalytic hydrogenation (ECH). This presentation discusses the elementary steps involved in the electro-absorption of H (electrochemical absorption) and the roles of the HUPD and HOPD species play in the process. It also explains that in the case of palladium (Pd) both HUPD and HOPD become absorbed, while in the case of metals that do not reveal the under-potential deposition of H phenomenon, it is only the HOPD species that participates in the process.

His contributions to platinum and nickel electrochemistry are of great importance to the fuel cell and water electrolysis technologies, because the degradation of these metals involves surface oxides that he has extensively studied. His research on platinum electrochemistry has identified a set of properties that make it the best electrocatalyst for several electrochemical technologies. This new knowledge is essential for the design and preparation of non-platinum electrocatalysts that mimic platinum and will be find application in novel fuel cell and water electrolysis technologies. Dr. Jerkiewicz has supervised over 70 highly qualified personnel (visiting researchers, post-doctoral fellows, PhD and MSc students, BSc students).
He has authored 150 publications (peer-reviewed papers, book chapters, papers in volumes of conference proceedings), edited four books, delivered 186 plenary, keynote and invited lectures, and 250 contributed conference presentations.

Jacobsen Award of the Electrochemical Society, Canadian Section, in 2012. In 2012, the President of Poland conferred on him the Knight’s Cross of the Order of Polonia Restituta (an equivalent to the Order of Canada). In 2018, the President of Poland bestowed on him the title of Professor of Chemical Sciences. In 2018, he was awarded the Eminent Visitor Award by the Catalysis Society of South Africa for his contributions to interfacial electrochemistry and electrocatalysis.
