Final Report for Project DE-FG02-05ER15718 Fluoropolymers, Electrolytes, Composites and Electrodes
- Clemson Univ., SC (United States)
This report is for a project that was initiated under the title “New Proton-Conducting Fluoropolymer Electrolytes for PEM Fuel Cells”, as part of the DOE program titled “Basic Research for the Hydrogen Fuel Cell Initiative”, Program Notice DE-FG01-04ER04-20. The project received 750,000 dollars in initial funding for a three-year term with a start date of August 15, 2005. Creager was PI and co-PIs were DesMarteau and Smith, all from Clemson. The project was renewed for a second three-year term with a start date of June 15 2008, again for 750,000 dollars, with the new title, “Fluoropolymers, Electrolytes, Composites and Electrodes”. Shortly after the renewal was put in place, co-PI Smith left Clemson to accept a position at the University of Texas at Dallas. After a period of no-cost extension the project was renewed on January 1 2013 for another three-year term, this time for a smaller amount ($525,000) and with Thrasher, a new senior hire at Clemson, as co-PI in place of Smith. DesMarteau had retired from Clemson by this time but was retained as a project advisor. After a final one-year no-cost extension for calendar year 2016, the project ended on December 31, 2016, giving it an active period of eleven and one-half years, from August 15 2005 to December 31 2016. The overall objective of this research project has been to create and understand the behavior of new fluoropolymer-based electrolytes and electrodes suitable for use in electrochemical energy storage and conversion devices. The objective was pursued via research on new fluorinated monomers, new polymers and polyelectrolytes (also known as ionomers), and new electrocatalyst supports that in some cases include chemically grafted electrolytes to promote rapid ion transport to electrocatalytically active sites (usually platinum nanoparticles) on the support. The research involved synthesis and characterization of new materials, and creation and use of new measurement techniques that address key properties of the materials, e.g. mixed electronic / ionic conduction in the absence of liquid electrolyte, that are relevant to their use in energy conversion and storage.
