Title of Contract, Award, or Gift: Proton Exchange Membrane and Cathode Catalyst Improvements for Fuel Cell Applications

Name of Granting or Contracting Agency/Entity: MPower Innovation, Inc.


Program Title: N/A


1.1.7 (SAM); The desired outcome of the Research Project is improving the cathode catalyst used in Proton Exchange Membrane (PEM) fuel cells. UNT will select and test candidate materials (i.e. Metal-Organic Frameworks, Covalent Organic Frameworks, Porous Organic Polymers or others) and supply catalyst samples to Mpower for testing. Mpower will provide catalyst performance feedback to UNT to assist in fine-tuning their material design and selection. In addition to improving the performance and durability of the PEM cathode catalyst, the secondary focus of work will be to improve the proton conductivity of the Proton Exchange Membrane (PEM), while increasing the PEM’s durability and resistance to H2/O2 Crossover. Here again, UNT will supply candidate materials to Mpower who will prepare and test membranes and provide feedback to USF. Objectives: Mpower will sponsor UNT to focus on improving the performance of two areas of PEM fuel cell components: The Cathode Catalyst and the Proton Exchange Membrane. Improved Cathode Catalyst: Deliverables: - Supply samples of UNT cathode materials to Mpower, which reduce the amount of Platinum needed by 25 % percent for testing in a PEMFC by the end of November or December 2020. - Supply samples of UNT cathode materials to Mpower which reduce the amount of Platinum needed by 50 % percent for testing in a PEMFC by June 2021.- Supply a sample of a thrifted Platinum cathode catalyst prepared using UNT materials, which reduces the amount of Pt by 50%, and maintains the equivalent performance compared to a commercial catalyst over 100 cycles or 100 hours. The reduction in Platinum will be compared to a reference material - current 20% Pt/Carbon examined using both standard ring rotating disk electrode (RRDE) tests and Membrane Electrode Assembly (MEA)-Single Fuel Cell Tests (employing the test protocols reported in the paper ACS Nano, 2019, 13, 8087-8098). - Monthly reviews of performance results of UNT lab tests. - Preparation of a 2nd generation, improved Proof of Concept catalyst in 2nd year of the Agreement. New performance targets to be agreed in June 2021.
