Abstract: An electrolytic cell, including a plurality of electrodes arranged to define a plurality of channels between adjacent electrodes is disclosed. Each channel is in fluid communication adjacent a first end with a first adjacent channel and is in fluid communication adjacent to a second end with a second adjacent channel. The electrolytic cell may be optimized for high concentration output of hypochlorite. The electrolytic cell may be used in conjunction with a plurality of cells operated collectively to provide operational efficiencies as compared to traditional hypochlorite generators.

Abstract: The present invention is directed to an electrochemical tool consisting of a potentiostat and user replaceable sensors and/or electrodes accompanied by an electronic memory that contains information that directs the potentiostat operation. The potentiostat is designed to operate with sensors employing a user customizable sensor and/or electrode memory. The customizable memory allows storing of information from a user and/or manufacturer related to a unique sensor identifier, calibration information, and/or an operational sequence to be employed by the potentiostat to properly operate the sensor and/or electrodes. A further aspect is to provide an electrode with pre-programmed electrode attributes.

Abstract: A method and apparatus measures the presence of total residual oxidant species in aqueous environments. More specifically, the apparatus is operable to measure hypohalites (e.g., hypochlorite and hypobromite) in water containing halide salts using electrochemistry. The apparatus can be a sensor having four electrodes—a reference electrode, a working electrode, and two auxiliary electrodes. The fourth electrode, i.e., the second auxiliary electrode, can be used to generate ionized water near and in contact with the working electrode. The ionized water can clean the working electrode to minimize effects due to scaling or biofilm formation. As such, the working electrode does not need the capability to clean itself. Thus, other elements, originally believed to be unsuitable for use in saline aqueous environments, can be used for the electrodes, for example, gold.

Abstract: The present invention is directed to the use of carbon nanotubes and/or electrolyte structures in various electrochemical devices, such as ultracapacitors having an ionic liquid electrolyte. The carbon nanotubes are preferably aligned carbon nanotubes. Compared to randomly entangled carbon nanotubes, aligned carbon nanotubes can have better defined pore structures and higher specific surface areas.
