JJ Group News
- Andres Godoy, Martin Birnbach, and Mathew Maramo were recognized at the 2024 MSE Banquet at UConn! https://mse.engr.uconn.edu/mse-banquet-2024-honoring-achievement-and-community-spirit.php
- Dr. Jasna Jankovic has been named the 2024 Distinguished Engineering Educator Award at UConn! https://mse.engr.uconn.edu/jasna-jankovic-named-2024-distinguished-engineering-educator.php
- Dr. Jasna Jankovic has recently received two grants with the DOE. One grant is led by Plug Power and the other is led by Mott Corporation and she will be UConn’s PI on both.
JJ’s Group visited MIT on 3/15 where they connected with Yang Shao-Horn’s team. They presented some of their current research and connected with other students and faculty in the discipline. They were able to tour their labs and engage in a scientific exchange, expanding in collaboration.
Andres Godoy published his article ” Understanding the Effects of Heat Treatment Temperature and Atmosphere on Platinum Nanoparticle Sintering Processes on Different Engineered Catalyst Supports (ECS) for Fuel Cell Applications” in the newest issue of ACS Applied Energy Materials and had his TEM images featured on the ACS Cover. https://pubs.acs.org/doi/10.1021/acsaem.3c02196
Dr. Jasna Jankovic has been awarded the NSF CAREER award for the project titled: “CAREER: Understanding degradation mechanisms in sustainable energy electrochemical systems using advanced characterization approaches.” Award period: 09/01/2021 – 08/31/26.

Multi-scale imaging and simulation

The deepest secrets of fuel cell catalyst layers in 3D
- A number of advanced structural characterization techniques have been developed in Prof. Jankovic team.
- Techniques are applicable to fuel cells, electrolyzers, batteries (with some further development).
- Advanced quantification of STEM-EDX maps was developed to provide important parameters in BOL and EOL samples: Pt loading, I/C ratio, CL porosity, OER catalyst agglomerate size distribution, Pt and Ionomer profiles etc.
- The technique provides important information about degradation effects on catalyst laters
- Capability in ionomer imaging in catalyst inks and layers (2D and 3D)
- 3D imaging, reconstruction and simulation of catalyst layers, MPL and GDLs have been demonstrated
- A number of correlations with performance of CL properties has been established
- Great potential of using these techniques to provide understanding of FC performance and degradation and input into mathematical models
- Potential for improved CL design and choice of materials
