QuantumSphere’s Patents to Alter Markets

QuantumSphere, Inc. of Santa Ana, California, filed two patents related to the fuel cell and battery industry to permit customization of nanometallic-additives, thus increasing power and efficiency.

The company’s existing technology framework, which enables battery and fuel cell manufacturers to address novel methods to produce uniform air cathodes. is supported by the first patent. This apparatus, exploiting unique, proprietary features in nanopowder handling, enables the production of air cathodes in small test sample sizes up to continuous production capability. This allows battery manufacturer’s R&D facilities to accomplish complex experimental designs related to gas electrode development while enhancing scale–up capability of resulting designs.

Using nano-sized transition metal catalysts and alloys, the second patent addresses gas diffusion electrodes for the fuel cell and metal air battery industry. The nanometal- containing cathodes can be used with many types of batteries and fuel cells, including Zn/air, Li/air, hydrogen and direct methanol fuel cells. Additionally, because of their flexibility, they may conform to a variety of surface contours, creating freedom in cell design to power a wider variety of devices.
