Weber Research Group

The Weber group explores electrochemical-based energy-conversion materials and assemblies across various technological platforms and applications. We conduct fundamental research on applied problems, with work focused mainly on exploration of transport phenomena. We comprise a multidisciplinary team of electrochemists, chemical engineers, mechanical engineers, theorists, and material scientists, including undergraduates, graduate students, and postdoctoral scholars. We work extensively with industry, academia, and national laboratories, including being key partners within the Fuel-Cell Performance and Durability (FC-PAD) consortium, the HydroGen – Advanced Water Splitting Materials EMN, and the Joint Center for Artificial Photosynthesis (JCAP). Most of our laboratories and offices are located in Building 70 or within JCAP.

Oyin Romiluyi publishes a paper on MEA design for CO2 reduction

Schematic of the catalyst-layer microenvironment and ionomer-catalyst distribution on a catalyst and support nanostructure based on the I:Cat ratio and ionomer content/coverage.
Paper is titled: "Membrane-electrode assembly design parameters for optimal CO2 reduction" doi.org/10.1002/elsa.202100186 In this work:
  • A Ag CO2R membrane-electrode assembly (MEA) that operates between 200 mA cm-2 and 1 A cm-2 with CO FEs of 78–91% is developed via systematic engineering of the cathode catalyst-ionomer microenvironment
  • Quantified the role of the cathodic ionomer-to-catalyst (I:Cat) ratio, catalyst loading, catalyst-layer thickness, and anode exchange-solution concentration on CO2R activity, cell… more

Doug Kushner is hired as a Project Scientist!

Doug has been a VIP (Very Important Postdoc) in the group for a number of years and was recently hired as a Materials Project Scientist/Engineer by the lab. We're so lucky Doug is staying with the group! He certainly earned the title of VIP over the years and will surely earn a new one in his new role.
