Professor John Weidner

CV of Dr. Weidner


Ph.D., North Carolina State University, 1991

B.S., University of Wisconsin - Madison, 1986


Professor Weidner's research group is involved in the synthesis and characterization of electrochemically active materials, and the design and operation of electrochemical processes. They have created novel synthesis routines, used a variety of electrocanalytical techniques, and developed sophisticated mathematical models to advance the fields of advanced batteries, electrochemical capacitors, fuel cells, and electrolysis involving gas-fed anodes (e.g., HBr, HCl, SO2). Their current research projects related to hydrogen and alternative energy. They are: 1) predicting the effect of volume change in intercalation electrodes (e.g., lithium in silicon); 2) synthesizing novel bi- and tri-metallic electrocatalysts for proton-exchange membrane (PEM) fuel cells and direct methanol fuel cells (DMFC); and 3) designing electrolyzers and developing electrocatalysts for use in thermochemical cycles for large scale hydrogen production from solar and nuclear energy.
