Files Two Patents - Development Enables Increased Power and Efficiency At Lower Production Costs
QuantumSphere, Inc. to Fundamentally Alter Battery and Fuel Cell Markets
Santa Ana, CA | Posted on November 09, 2005
QuantumSphere, Inc., the leading
manufacturer of metallic nanopowders for applications in aerospace, defense,
energy, electronics and other markets demanding advanced material
applications, announced it filed two patents related to the fuel cell and
battery industry allowing for customization of nanometallic-additives for
increased power and efficiency. The first patent supports the company’s
existing technology framework that will enable battery and fuel cell
manufacturers to address novel methods to produce uniform air cathodes.
Unique, proprietary features in nanopowder handling enables the production
of air cathodes in small test sample sizes up to continuous production
capability using the same apparatus, thereby enabling battery manufacturer’s
R&D facilities to accomplish complex experimental designs related to gas
electrode development while enhancing scale-up capability of resulting
The second patent addresses gas diffusion electrodes for the fuel cell and
metal air battery industry using nano-sized transition metal catalysts and
alloys. These nanometal-containing cathodes can be used in conjunction with
a variety of types of battery and fuel cells, including Zn/air, Li/air,
hydrogen and direct methanol fuel cells. In addition, they are flexible and
may conform to a variety of surface contours, allowing for more freedom in
cell design to power a wider variety of devices.
“This technology allows QuantumSphere to provide customers the capability of
developing and verifying cathode designs specific for their applications.
For example, a methanol fuel cell and a zinc air battery have very different
power and voltage requirements,” Robert Dopp, President, DoppStein
Enterprises, Inc. “Ratios of QuantumSphere-produced nanocatalysts can be
optimized using this technology. The resulting cathodes use catalysts never
tested before because the method to make small cathode samples did not
exist, but also because, until recently, no one knew how to make the
metallic nanopowders uniformly and in quantities large enough to test.
QuantumSphere and DoppStein Enterprises, Inc, working in partnership, have
resolved both of these issues. These inventions will lead to more efficient
and more powerful fuel cells and metal air batteries using QuantumSphere’s
nanocatalyst and powder handling process.
“This new cathode making process, coupled with the addition of highly active
catalyst is invaluable for the production of high-power density fuel cells
and batteries which are streamlined and can be tailored to a wide array of
devices - thereby providing significant performance advantages in the next
generation cell phones, cameras, and other portable electronics,” said Dr.
Kimberly McGrath, Director of Fuel Cell Research, QuantumSphere, Inc.
“QuantumSphere will continue to work with world-class partners, such as
DoppStein Enterprises and others, to research, develop, produce and ship
alternative catalyst products on a mass scale at a fraction of the cost,”
Dr. McGrath added. As Director of Fuel Cell Research, Dr. McGrath also
tailors catalysts for various cell types and operating temperature regimes,
and designs new fuel cell systems for small, portable applications that will
be efficient at room temperature with minimal catalyst loading.
