ANL Research Highlights
During my time as a post-doc, my research focused on the development of catalyst materials for the autothermal reforming of gasoline and other liquid fuels to produce hydrogen for fuel cell powered vehicles. One of the key issues that my research addressed was whether perovskite oxide materials containing a small amount of nickel would remain a single phase under the conditions of autothermal reforming at 700°C. Another question that my research addressed was whether these materials would resist carbon deposition, especially when the fuel contained sulfur.
New Endeavors
I am now a staff scientist in the Chemical Sciences and Engineering Division at Argonne National Laboratory.
My research focus has remained hydrogen production for fuel cell vehicles, but my current focus is on two different methods: 1) high temperature steam electrolysis and 2) the sulfur-iodine thermochemical cycle. I have been working to develop alternative materials for both the anode and cathode used in high temperature steam electrolysis. I have also been researching the causes of component degradation during long-term (>2000 h) testing of high temperature steam electrolysis systems. My involvement with the S-I cycle has been in reducing the temperature of one of the steps in the cycle, converting SO 3 to SO 2 , by 200°C using electrolysis. Additionally, I have been participating in projects related to fuel cell development by using electron microscopy to characterize electrode materials being developed for polymer electrolyte membrane fuel cells.
