Santa Ana, CA, U.S.A. – September 26, 2005 – QuantumSphere, Inc., the leading manufacturer of metallic nanopowders for applications in aerospace, defense, energy and other markets demanding advanced material applications, announced it opened a new manufacturing facility and relocated the firm’s national headquarters to Santa Ana, CA, just ten minutes from Orange County’s John Wayne Airport. QuantumSphere’s expanding customer base and science team necessitated the need for a new location to meet explosive product demand. QuantumSphere is the only supplier of the world’s highest quality nano nickel/cobalt alloy and other magnetic, conductive and catalytic metallic nanopowders, including QSI-nano™ nickel (n-Ni), QSI-nano™ silver, QSI-nano™ copper, and other proprietary alloys. These materials will replace platinum as the main catalyst in fuel cells and other membrane electrode assemblies and provide a renewable source of power. This news follows the company’s previous announcement that an internationally renowned, fully independent organization validated that QuantumSphere successfully achieved consistent and repeatable performance and validation milestones with QuantumSphere’s proprietary high-quality nano-Nickel/Cobalt alloy for use in battery and fuel cell electrodes.Ê As a result, QuantumSphere provides a clear replacement solution in the multi-billion dollar platinum electrode market that will deeply impact the OEM and consumer marketplace while reshaping the platinum group metal catalyst landscape. The new manufacturing facility and corporate headquarters is located at:

2905 Tech Center Drive,

Santa Ana, CA 92705.

Sales, Technical and Customer Support Services personnel can be reached at 714-545-NANO (6266).
