Patent number: 8377149Abstract: A process for making a catalytic electrode, a process for making an electrochemical cell with a catalytic electrode, and an electrochemical cell made according to the process. The catalytic electrode has an active layer comprising a catalytic material, an electrically conductive material and a binder, and a gas diffusion layer including a material that is permeable to gas entering or escaping from the cell but essentially impermeable to electrolyte. The gas diffusion layer is adhered to the active layer by a patterned pressure bonding process to provide the catalytic electrode in which the entire gas diffusion area is adhered to the active layer, with areas of relatively high and relatively low adhesion. The electrode has a high overall bond strength, and the permeability of the gas diffusion layer remains high it has been adhered to the active layer to provide excellent high power capability.Type: GrantFiled: December 14, 2010Date of Patent: February 19, 2013Assignee: Eveready Battery Company, Inc.Inventors: Robert Brian Dopp, Gary A Laisy

Publication number: 20110192717Abstract: A device and system useful for highly efficient chemical and electrochemical reactions is described. The device comprises a porous electrode and a plurality of suspended nanoparticles diffused within the void volume of the electrode when used within an electrolyte. The device is suitable within a system having a first and second chamber preferably positioned vertically with respect to each other, and each chamber containing an electrode and electrolyte with suspended nanoparticles therein. When reactive metal particles are diffused into the electrode structure and suspended in electrolyte by gasses, a fluidized bed is established. The reaction efficiency is increased and products can be produced at a higher rate. When an electrolysis device can be operated such that incoming reactants and outgoing products enter and exit from opposite faces of an electrode, reaction rate and efficiency are improved.Type: ApplicationFiled: April 18, 2011Publication date: August 11, 2011Applicant: QUANTUMSPHERE INC.Inventor: Robert Brian Dopp
