May 2004 meeting announcement
-----------------------------------------------------
Speaker: Dr. Ramesh Koripella, Motorola, Tempe, AZ
Topic: Fuel Cells for Portable Power Applications
Date: May 18, 2004, Tuesday
Time: 5:30-6:00 pm Social/Refreshments, 6:00-7:00 pm
Presentation, 7:00 pm Dinner
Venue: Motorola, 2100 E Elliott Road, Tempe AZ
Abstract
Power demand for portable electronic devices is
constantly increasing with the improved performance
and added functionality of the devices. Currently Li
ion batteries are the main energy source for most
portable electronic devices. Improvements in the
energy density of the Li ion batteries are
incremental, which limits the amount of energy stored
in the cell. Frequent recharging of the batteries is
also a major inconvenience. Fuel cells are actively
being pursued by various companies as a potential high
energy density alternative power source for portable
electronic applications. The choice of the fuel and
the design of a compact fuel cell system are key
issues in the development of portable fuel cell power
sources. Hydrocarbon fuels such as liquid methanol
are very attractive fuels for portable applications
because of their energy density and ease of storage
and transport. Methanol fuel can be used directly as
a dilute solution in direct methanol fuel cells (DMFC)
or it can be reformed in-situ into a hydrogen rich gas
at relatively low temperatures (200-300?aC) to run
hydrogen fuel cells. For each fuel cell system,
there are critical development issues in areas such as
fuel delivery, fuel processing, electrochemical energy
conversion and development of miniature system
components.
In this presentation, a brief overview of the fuel
cell technology, choice of fuels and the types of fuel
cells suitable for portable power applications will be
given. Challenges involved in the development of fuel
cell based portable power sources, issues involved in
the commercialization of this technology and
Motorola¡¦s development efforts in this will be
discussed.
Biography
Ramesh Koripella is a distinguished member of the
technical staff with Motorola - Microelectronics and
the Physical Sciences Laboratory, in Tempe, AZ. He
has been with the Motorola research labs, for 11
years, involved in the R&D efforts on Integrated
Passives in LTCC modules, Hydrocarbon Exhaust Gas
Sensor and for the past 5years on the Portable Fuel
Cell Power Source development efforts. Prior to
Motorola, Ramesh was with KEMET Electronics in
Greenville, SC for 7years, involved in the multilayer
ceramic capacitor R&D efforts on new dielectric
materials and on improving the thermal shock
reliability of the multilayer ceramic capacitors. He
has 12 patents issued, published several papers and
gave presentations at various technical conferences.
Ramesh holds a Ph.D. from Univ. of Southern
California, LA, in Materials Science and an MBA from
Clemson University.
