MTI Micro's Mobion(R) Exceeds Li-Ion Battery

- Consumer Prototype Provides Over a Month of Typical Cellular Phone Usage -

ALBANY, N.Y., Sept. 21 /PRNewswire-FirstCall/ -- MTI MicroFuel Cells Inc.
("MTI Micro"), the developer of the award-winning Mobion(R) micro fuel cell
technology and a subsidiary of Mechanical Technology Incorporated
(Nasdaq: MKTY), announced today it achieved its third quarter milestone of
developing a prototype for the consumer market that exceeds the energy density
of average Li-ion batteries with its Mobion(R)-1 product platform.

This prototype of a charger accessory -- the size of a small paperback
novel -- displays the strengths and innovative qualities unique to MTI Micro's
Mobion(R) technology such as 100% methanol, light weight, and most importantly
longer device run time -- a feature that customers deeply care for.
This Mobion(R) accessory charger prototype provides over 95Wh of
continuous run-time and allows users to charge a number of portable electronic
products. For example, it is designed to charge an average cell phone battery
over 30 times or give customers about a month of phone usage on one full
charge per day. It is also designed to allow customers to take more than
5,000 pictures on a small portable digital camera, or recharge a 5 gigabyte
video/audio MP3 player over 40 times.
"This prototype's form factor allows users to carry more power without the
inconvenience of carrying multiple chargers and adaptors, and hunting for wall
outlets," said Juan Becerra, Vice President of Market and Business Development
at MTI Micro. "This accessory prototype has 3 to 5 times more capacity than
any other charger in its class, and it addresses current trends in portable
electronics."
Trends in portable electronics are creating a growing need for longer-
lasting power. Consumers want increased intelligence and wireless
functionality -- for example more memory, color screens, satellite TV, and
multi-purpose devices like cell phones that are also digital cameras, PDAs,
and MP3 players. In addition, typically in the consumer electronics industry,
new technologies enter the market with form factors that gives both OEMs and
end-users the flexibility to choose the new technology as an option, and are
normally external to the device at first. Examples of these technologies
include modems, Wi-Fi, and 3G wireless such as HSDPA and EVDO cards which were
not embedded within laptop computers when first introduced into the market.
Now, many of these technologies are included inside the laptops.
In the consumer market, MTI Micro recently signed an exclusive agreement
with Samsung Electronics -- one of the largest and most innovative mobile
phone suppliers in the world -- to develop Mobion(R) fuel cell prototypes for
various mobile phones and accessories. MTI Micro is working very closely with
Samsung in customizing prototypes scheduled to be delivered to Samsung for
testing in the fourth quarter.
"This Mobion(R)-1 prototype is an indication of our technology progress
that coupled with our consumer electronic and fuel distribution partners bring
us a step closer to our ultimate goal -- making Mobion(R) a standard power
source used for powering all types of mobile products in military, industrial,
and consumer applications," said Peng Lim, CEO of MTI Micro.
MTI Micro remains on track to meet its milestone of a customer
demonstration of a product-intent military portable power system in the third
quarter.
