| 20080220278 | High rate electrochemical device - 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. Ideally, this device and system can be used to rapidly produce significant quantities of high purity hydrogen gas with minimal electricity cost. | 09-11-2008 |
