A novelfuel cell which can directly use native polymeric biomasses, such as starch, cellulose, lignin, and even switchgrass and wood powders will be discussed. This fuel cellcombines some features of solar cells, fuel cells, and redox flow batteries. Specifically, an oxidation/reduction ion pair, such as Fe2+/Fe3+, or polyoxomatelate, are used as catalyst to oxidize biomass by either absorbing solar light or heat energy. The power density of the solar-induced hybrid fuel cell powered with raw biomass could reach ~50 mW/cm2.Unlike most cell technologies that are sensitive to impurities, the cell reported in this study is inert to most organic and inorganic contaminants present in the fuels. The fuel cell is completely noble metal free. The similar fuel cell system can also be converted to electrolysis cell for hydrogen production at low temperature using native biomass directly.
Professor Yulin Deng received his Ph.D. from Manchester University, United Kingdom in 1992. After he worked as a postdoc research fellow at McMaster University in Canada, he was appointed as an assistant professor at Institute of Paper Science and technology (IPST) in 1995, and promoted to associate professor in 1998. He moved to Georgia institute of Technology in 2003, and promoted as a full professor in 2008.
Prof. DENG is a Fellow of the International Academy of Wood Science, and hold a James C. Barber Faculty Fellow position at Georgia Institute of Technology. He received AIChE Chase Award in 2013. He is a member of ACS, AIChE and TAPPI. He is also an associate editor of two journals, and an editorial board member for another 7 journals. He published more than 250 peer reviewed papers covering the areas of bioenergy, biomass, biofuel, fuel cell, nanosceince and nanotechnology.
