| Austin,
TX — A technology to produce fuel cells that serve as easily replaced,
lightweight power sources for cell phones, laptops, MP3 players and other
devices is being developed by a team led by a mechanical engineer at The
University of Texas at Austin.
A team of nine faculty led by Dr.
Arumugam “Ram” Manthiram has received $3.5 million from the U.S. Office
of Naval Research for three years to develop novel materials and manufacturing
processes for methanol-powered fuel cells. The naval office is expected
to provide $2.3 million more for two additional years on this Multi-disciplinary
University Research Initiative grant about this alternative to lithium
ion batteries.
Power sources based on methanol-powered
fuel cells could weigh about half as much as their lithium ion counterparts.
The methanol-powered fuel cells would also permit consumers and military
personnel to carry replacement methanol cartridges and avoid recharging
devices using electrical outlets.
“Soldiers wouldn’t have to look for
an electrical socket to recharge their batteries,” said Manthiram, “and
fuel cells would significantly reduce the weight soldiers have to carry.”
To investigate methanol-powered fuel
cells, the holder of the B.F. Goodrich Endowed Professorship in Materials
Engineering is working with seven university colleagues and a mechanical
engineering colleague at Stanford University.
The other University of Texas at
Austin participants are: Dr. Allen Bard (the Norman Hackerman-Welch Regents
Chair in Chemistry); Dr. Joseph Beaman (the Earnest F. Gloyna Regents Chair
in Engineering and chair of the Department of Mechanical Engineering);
Dr. Christopher Bielawski (assistant professor of chemistry and biochemistry);
Dr. David Bourell (the Temple Foundation Endowed Professor No. 2); Dr.
Venkat Ganesan (the Chevron Centennial Teaching Fellow in Chemical Engineering);
Dr. Jeremy Meyers (assistant professor of mechanical engineering, and a
member of the university’s Center for Electrochemistry along with Bard
and Manthiram); and Dr. Kristin Wood (the Cullen Trust for Higher Education
Endowed Professor in Engineering No. 1). The Stanford University participant
is: Dr. Friedrich Prinz, the Rodney H. Adams Professor in the School of
Engineering.
Manthiram, Bard, and other group
members will develop cheaper, more efficient materials for prompting the
chemical reactions that generate electricity in methanol-powered fuel cells.
Cheaper, more efficient membranes that serve as proton transport medium
for these chemical reactions will also be studied. To develop an efficient
manufacturing process, Beaman and colleagues will use computer-aided selective
laser sintering and predictive process controls for producing components
such as carbon plates that control the flow of methanol and oxygen to membrane-electrode
assemblies. These membrane-electrode assemblies, which generate electricity,
will also be produced using other types of advanced manufacturing processes.
The researchers will also study how
to integrate the different components that would be manufactured to produce
an efficient methanol-powered fuel cell system.
