范德比尔特大学教授

电化学学会会士、美国化学工程师学会会士

北美膜学会前会长

Peter Pintauro is the H. Eugene McBrayer Professor Emeritus in the Department of Chemical and Biomolecular Engineering at Vanderbilt University. He received B.S. and M.S. degrees in Chemical Engineering from the University of Pennsylvania and a Ph.D. in Chemical Engineering from the University of California, Los Angeles. He joined the faculty of Tulane University in 1986, where he rose to the rank of Professor of Chemical Engineering in 1994. In July 2002, he moved to Case Western Reserve University, as Chair of the Department of Chemical Engineering, and was appointed Kent Hale Smith Professor of Engineering in October 2004. From 2008 until 2013, he was Department Chair at Vanderbilt. He retired as a full-time tenure-track Professor at Vanderbilt in 2023. His research interests are in the areas of membrane science, fuel cells, batteries, and organic electrochemical synthesis. He is a Fellow of the Electrochemical Society, a Fellow of the American Institute of Chemical Engineers, a past President of the North American Membrane Society, the 2018 U.S. Department of Energy’s Fuel Cell R&D Award recipient, and the 2023 recipient of the Electrochemical Society’s Walter van Schalkwijk Award in Sustainable Energy. He recently co-founded Bardo Climate Inc., a start-up company to commercialize products based on patents from his membrane work at Vanderbilt University.

The goal of many fuel cell research teams is to lower the overall cost and improve the  durability of the membrane-electrode-assemblies (MEAs) that form the heart of a proton-exchange membrane (PEM) fuel cell. Conventional and expensive Pt/C powder catalyst fuel cell cathodes suffer from poor durability due to carbon corrosion and metal dissolution which limit their operational lifetime.  Alternative less-expensive platinum-group-metal-free (PGM-free) cathode catalysts are a possible solution, but problems with low power and very poor durability remain unsolved. Recently, the use of perfluorosulfonic acid binders such as NafionÔ in fuel cells has become an issue, given the healthcare concerns of fluorinated ‘forever compounds.” This presentation will address these issues.  First, it will be shown that the addition of a fluorinated-ethylene-propylene dispersion (FEP TeflonÔ) to the Nafion binder of a Pt/C cathode will stop carbon corrosion without sacrificing fuel cell power generation. A Nafion/FEP binder with sufficient FEP content also stabilized the power output of fuel cell MEAs that employed a PGM-free catalyst cathode. In a third project, a water soluble polymer, when added to the hydrocarbon ionomer binder Pemion™ (from Ionomr Innovations, Inc.), resulted in very high MEA power output and excellent cathode durability, which was attributed to the formation of nanopores in the binder (generated  by extracting the water soluble polymer) which enhanced the transport of air in and water out of the cathode during fuel cell operation.  For the Nafion/FEP and Pemion work, the method of preparing electrodes and MEAs will be presented and fuel cell performance results will be discussed and contrasted with data in the literature.
