Fuel
Cell Research
Background
Current
funding is from the US Army and State of Indiana (21st Century).
This supports ~ 10 faculty, 10 graduate students, 5 post
doctoral
associates in the Department of Chemical & Biomolecular Engineering
and
Radiation Laboratory. These programs are
primarily aimed at portable fuel cell applications.
Issues
To
develop portable fuel cells based on
conventional consumables (methanol and air) for small electronic
appliances
(e.g., lap-tap computers)
To
minimize the use of precious metals by
developing new electrode materials and membrane assembly
Our Research
Focus.
Utilize
carbon nanostructures
(fullerenes, carbon nanotubes etc) as support to boost the electrode
performance
Design
of new metal catalysts and
composites for improving the efficiency of electrode reactions
Develop
membrane assembly and
evaluate the overall performance in portable fuel cells (Direct
methanol and
hydrogen fuel cells)
Response of SWCNT
alignment in a dc electric field
Progress So Far
Electrophoretically
deposited
fullerene (C60) films are capable of
serving as good
nanostructured carbon supports.
One-step solubilization of
carbon
nanotubes in an organic solvent and their alignment in a dc field has
been
achieved.
Electrophoretic deposition
of
nanotubes on various electrode surfaces (Conducting glass, Toray paper,
carbon
cloth) – a more effective way
of
depositing carbon nanostructures than the commonly used ink-paint
method.
Preparation of small Pt
nanoparticles (2-10 nm) using sonolytic and electrochemical reduction
methods.
Demonstration of carbon
nanotube
based MEA assembly in a Prototype Hydrogen Fuel Cell
