【学术预告】Fuel cell revisited: Lost in space or finally down to earth?


报告人:Dominic F. Gervasio教授(University of Arizona, USA)





Since the 1960s, fuel cells have reliably provided electrical power in space craft for the exploration of outer space. When OPEC (the organization of petroleum exporting countries) disrupted global oil markets in 1973, fuel cells were touted as the way to provide clean efficient automotive power sources that would extend the life of petroleum reserves by roughly a factor of 4, that is, roughly the ratio of fuel cell efficiency to internal combustion engine efficiency. However, the fuel cells used in outer space are prohibitively expensive to use on earth for applications like powering automobiles. Now 45 years after the OPEC disruption, automobile engines still burning gasoline to power automobiles, and perhaps air pollution is an even bigger problem than oil supply. And the fuel cell power source still has not materialized, and it has become clear that a battery power source alone is not the answer for automobile power.

So, where do we stand? A new phase of fuel cell research is on the horizon. With new smarter materials, process- and product-design, we can finally have fuel cell powered automobiles which give clean and efficient power for automobiles, and other applications, like emergency and remote residential power, load levelers, etc. An overview of fuel cell developments will be presented. This will show the evolution of fuel cell technology and how fuel cells can finally be brought down to earth. How? Terrestrial fuel cell can be had by developing and using membranes which conduct only protons, because this leads to practical fuel cell power systems.

Dominic Gervasio教授简介:

Prof. Gervasio is a research professor in the Department of Chemical and Environmental Engineering at the University of Arizona. Don earned the Ph. D. in inorganic chemistry and gained extensive experience in electrochemistry while a Senior Research Associate and Instructor at Case Western Reserve University in Cleveland, Ohio. In 1993, Don led research efforts for making new electrochemical DC power supplies at the Bell labs in Red Bank, NJ and in 1997 at Motorola in Tempe, AZ. In 2003, Don returned to academia at Arizona State University and in 2009 moved to the University of Arizona. Don’s research involves materials for power generation, energy storage, electrochemical synthesis and corrosion. Don has authored over 60 peer reviewed publications. Don was awarded the 2016 Tech Launch Arizona I2 (Innovation and Impact) awardee, "Technology Ventures Innovator of the Year" in 2007 by the Arizona Technology Enterprises; is on the Editorial Board of the Journal of Power Sources (Elsevier) since 2007; has served as the Chairman of the Arizona Section of the Electrochemical Society (ECS) from 2001-2012 and since 2013 is the Secretary of the Arizona section of the ECS. Don has been an invited speaker all over the world and is actively involved in international education and cooperative research in Electrochemistry and has been invited to teach short courses in Electrochemistry Engineering in Mexico, China and Russia. In 2016, Don became a founding member of two new startup companies, METOXS and CALTRODE, to develop 2 molten salt technologies, one to extract and refine metal and the other to sense and control electrochemical processes, like metal deposition and corrosion.
