His current research and activities involve understanding and optimizing fuel-cell and electrolyzer performance and lifetime using advanced modeling and diagnostics, understanding flow batteries for grid-scale energy storage, and analysis of solar-fuel generators and CO2 reduction to value added products. Dr. Weber has coauthored over 200 peer-reviewed articles and 11 book chapters on fuel cells, flow batteries, and related electrochemical devices, developed many widely used models for fuel cells and their components, has been invited to present his work at various international and national meetings, and has 6 patents. He is the recipient of a number of awards including a Fulbright scholarship to Australia, a 2012 Presidential Early Career Award for Scientists and Engineers (PECASE), the 2014 Charles W. Tobias Young Investigator Award of the Electrochemical Society, the 2016 Sir William Grove Award from the International Association for Hydrogen Energy, a 2020 R&D100 award for microelectrode development, the 2023 Fuel Cell Award from the Department of Energy, and the 2023 Research Award of the Energy Technology Division of the Electrochemical Society. He is a Fellow of The Electrochemical Society.
