Dr. Boris Merinov jointed Caltech in 1999 first as a visiting research associate and then as associate scientist (2002), senior scientist (2010) and lead scientist (2012). He is an internationally recognized expert in materials and processes for fuel cell and battery applications. Dr. Merinov has been associated with top research institutes, such as Institute of Crystallography, Moscow, Russia (1977-1999), University of Munich (Humboldt Fellow, 1992), University of Montpellier, France (French Ministry
of Research and Technology Research Fellow, 1993; Visiting Scientist and Visiting Professor, 1995-1996), Hahn-Meitner-Institute Berlin GmbH (Visiting Scientist, 1994), and University of Hamburg/DESY (Volkswagen Fellow, 1996-1997; Humboldt Fellow, 1998-1999). He is a pioneer in the study and characterization of an emergent class of materials, solid acids. In collaboration with Prof. Baranov, Dr. Merinov discovered superprotonic phase transitions in a number of solid acid materials, including
CsH2PO4 (Solid State Ionics 36, 279-282, 1989) which is now used in a new type of fuel cells, solid acid fuel cells (Nature 410, 910-913, 2001), invented by Professor
Sossina Haile and her former students Dane Boysen and Calum Chisholm (SAFCell). Dr. Merinov established himself as one of the foremost authorities in the field of solid state proton conductors through his unique structural investigations of solid acids, which were crucial for understanding very deep aspects of structure arrangements,
proton transport and phase transitions in these materials. Examining crystal structures of superprotonic phases of solid acids by X-ray single crystal analysis, he found unusually clear localizations of dynamically disordered hydrogen atoms at their partially occupied crystallographic positions and proposed a hypothesis about “dynamic twinning” in the solid acid superprotonic phases to explain such unusual phenomenon (Physica Status Solidi 218, 365-378, 2000; Z. Kristallogr. 225, 401403, 2010).These fundamental studies enabled to understand the potential of solid acids as advanced solid electrolytes.
At present, Dr. Merinov successfully develops new approaches and techniques for computational modeling of solid electrolytes, high-conductive polymers, transport phenomena, catalytic reactions, electrode/electrlolyte interfaces, and other physico-chemical processes in fuel cells and batteries. In co-authorship he has published a series of papers about oxygen reduction reaction (ORR) mechanisms on metal and metal alloy catalyst surfaces advancing the present understanding of ORR in electrochemical devices. Development of predictive computational models performed by Dr. Merinov, allows the experimental synthesis and characterization to be focused on the most promising materials, enabling more rapid progress in energy related technologies.
