Research areas

1.Multi-functional materials

  • Cation (or) anion conducting membranes for fuel cells, batteries, and electrolyzers
  • Mixed-conducting electroactive materials
  • Core-shell materials for lithium-ion battery cathodes [with Prof. Prakash]

2.Degradation mechanisms and component degradation mitigation.

  • PEM /AEM degradation mechanisms using 2D NMR spectroscopy
  • Electrocatalyst and support corrosion in fuel cells and electrolyzers
  • Li-ion battery degradation (thermal runaway) [with Prof. Prakash]

3.In-situ electrochemical diagnostics

  • In-situ measurements using microelectrodes embedded within PEM
  • In-situ fluorescence spectroscopy (estimation of free radicals within PEM)

4.Distribution of overpotential in electrochemical systems

  • Deconvolution of activation, ohmic and mass transport overpotentials in PEFCs
  • Gas-phase vs. condensed phase transport losses in PEFC electrodes
