About
Chulsung Bae is Ford Foundation Professor at Department of Chemistry & Chemical Biology (with a joint appointment at Department of Chemical & Biological Engineering), Rensselaer Polytechnic Institute. Broadly speaking, Bae's research group focuses on development of functional polymeric materials that might find applications in the areas of clean energy and environment technologies, using synthetic organic chemistry as a tool. Specific examples of projects include innovative ion conducting polymer electrolytes that can be used as a key component in next generation energy conversion and storage technologies, such as fuel cells, hydrogen production via water splitting, and redox flow battery, and functional polymers that can play a crucial role in energy efficient separation process.
Bae received BS in Polymer Science & Engineering at Inha University, MS in Materials Science at POSTECH, MS in Chemistry at University of Massachusetts at Lowell, and PhD in Chemistry at University of Southern California under the guidance of Surya Prakash and Nobel Laureate George Olah. After postdoctoral research with John Hartwig at Yale University, he started independent academic career at University of Nevada Las Vegas (UNLV) as an Assistant Professor in 2004. In 2012 Bae relocated his research group to Rensselaer Polytechnic Institute. Dr. Bae received a number of awards including New Investigator Award of UNLV (2005), National Science Foundation CAREER Award (2008), and RPI School of Science Outstanding Research Award (2016). In 2017 Dr. Bae received a $2.5 million contract from the U.S. Department of Energy's Advanced Research Products Agency-Energy (ARPA-E) to develop innovative solid ion conducting materials for next generation renewable energy conversion and storage technology.

Research
Dr. Bae's research areas encompass organic chemistry, green chemistry, polymer chemistry, and materials science. Broadly speaking, Dr. Bae's research group focuses on development of functional organic/polymeric materials that might find special applications, particularly for clean energy and environment technologies, using synthetic organic chemistry tools. Currently his group pursues two major branches of research in that direction: (i) ion-conducting polymer materials for applications in energy conversion device and (ii) gas separation polymer membrane.
Ion-conducting Polymers for Clean Energy Technology Applications
We choose to go to the moon in this decade and do the other things, not because they are easy. Fuel cells hold significant promise as an alternative energy technology with many advantages over the fossil fuel combustion such as high energy conversion efficiency and environmentally friendly operation. Additionally, fuel cells offer high energy density by virtue of their use of chemical fuels, which is a limitation in many other electrochemical energy storage and conversion devices. Of the different types of fuel cells, proton exchange membrane fuel cells (PEMFCs) are the most attractive candidate for automobile application because of high power density. Polymer electrolyte membrane (PEM), typically made of ion-conducting polymers, critically determines the power output performance of PEMFCs device. So far perfluorosulfonic acid ionomers such as Nafion have been the most widely tested PEM material. Unfortunately, Nafion has serious drawbacks that prevent widespread commercial application in PEMFCs, including high cost, rare availability of fluorine-containing precursors, reduced proton conductivity above 100?, and high methanol crossover in direct methanol fuel cells. The goal of this research project is to develop novel proton-conducting materials that will significantly advance progress in fuel cell technology. Recently, we have developed a new controlled polymer functionalization method based on borylation of C-H bonds in aromatic polymer. This new synthetic method has allowed to incorporate various types of sulfonate groups into polymers. Synthesis and characterization of these new ionic polymers will advance our understanding of relationships between chemical structure and performance of the materials in fuel cell properties at molecular level and, eventually, lead to development of next-generation PEMs that overcome the limitation of currently available fuel cell membranes.
