COSTA MESA, CA, U.S.A. – April 26, 2005 – QuantumSphere, Inc., the leading manufacturer of metallic nanopowders, working toward catalyzing the future for fuel cells, batteries, and hydrogen generation, is moving forward with the collaboration of Robert Dopp, of Doppstein Enterprises, Inc. (DSE). Together they are testing QuantumSphere’s new line of nano-catalysts in functioning air electrodes to better identify significant parameters in the development cycle. Mr. Dopp has developed a cathode manufacturing process expressly designed to manufacture small "coupons" of highly uniform, very active and reproducible gas diffusion electrodes. These are typically used in metal air batteries, alkaline fuel cells, other air breathing systems as well as hydrogen generation cells. By producing the finished product from the new generation of catalyst, QuantumSphere can engineer their particle size distribution, composition and distribution to optimum performance. This is something that quantitative and physical measurements cannot achieve; the collaborative efforts of QuantumSphere and DSE can.

"We are extremely pleased to work with Robert Dopp who is an industry veteran in the fuel cell, battery and related industries," said Kevin Maloney, CEO, QuantumSphere, Inc. "During his three decades of battery R&D, resulting in 36 related patents bearing his name, he has designed several production air cathode machines, making the highest rate air cathode in the world. He has helped to develop a consumer battery with over four times the energy density of Alkaline cylindrical cells, and many tens of times higher energy than many rechargeable batteries," Maloney added.

The efficient generation of hydrogen from a source other than petroleum (i.e. Hydrolysis cells) and the efficient conversion of hydrogen into energy (i.e. Fuel cells) are two of the most pressing needs of the century. Platinum is currently the only known catalyst to satisfy this development need and there is not enough platinum available in the world. Through this twofold effort between QSI and DSE, we hope to electrochemically demonstrate that nano-materials are an excellent replacement for platinum.

QuantumSphere is one of the leaders in the race to develop catalysts that do not contain platinum. To achieve this goal, they have developed a line of pure nickel, cobalt, copper, silver and other metallic nanoparticles" said Robert Dopp. "Their unique process also allows for the production of nano-sized catalysts utilizing the active cobalt nickel oxides and chelated cobalt cyclic-porphyrins. This development is not only exciting – but what they are doing is vital," Dopp added.
