    Abstract: An electro-catalytic honeycomb for controlling exhaust emissions, which adopts to purify a lean-burn exhaust, comprises a honeycomb structural body, a solid-oxide layer and a cathode layer. The honeycomb structural body includes an anode, a plurality of gas channels, and a shell. The anode is formed as a backbone, the gas channels are formed inside the backbone for passing the exhaust, and the shell covers an outer surface of the anode. The solid-oxide layer is adhered to an inner surface of the anode and connects the shell so as to encapsulate the anode. The cathode layer is adhered to a tube wall of the solid-oxide layer and has an oxidizing environment. The anode has a reducing environment. The reducing and the oxidizing environment facilitate an electromotive force to occur between the anode and the cathode layer to promote a decomposition of nitrogen oxides of the exhaust into nitrogen and oxygen.

Water (H2O) is supplied to a vessel, whether ashore, docked or underway, and is systematically converted into hydrogen and oxygen. The energy required for this process may be provided by any renewable or non-renewable source. The H2 produced is either utilized at once or stored. Energy is released from the H2 by one or more power plants.

  • Patent number: 6544400
    Abstract: A hydrogen source system delivers a controlled fuel stream to applications, using wicking to control the contact between a mixture of NaBH4, NaOH and H2O and a hydrolyzing catalyst to create a feedback mechanism to automatically maintain a constant pressure production supply of hydrogen. A small compact device packaged for storage, the system operates in any orientation and is mobile. The system is a small portable packaged hydrogen generator for small fuel cells to power applications that are currently powered by batteries. These packaged devices have higher energy per unit mass, higher energy per unit volume, are more convenient for energy users, environmentally less harmful, and less expensive than conventional power sources.

  • Patent number: 6527920
    Abstract: An electroplating apparatus prevents anode-mediated degradation of electrolyte additives by creating a mechanism for maintaining separate anolyte and catholyte and preventing mixing thereof within a plating chamber. The separation is accomplished by interposing a porous chemical transport barrier between the anode and cathode. The transport barrier limits the chemical transport (via diffusion and/or convection) of all species but allows migration of ionic species (and hence passage of current) during application of sufficiently large electric fields within electrolyte.

  • Patent number: 6458257
    Abstract: The present invention provides for the electrochemical generation of ozone for use in “point-of-use” applications. The electrochemical ozone generators or systems of the present invention may be used to provide disinfected water, ozone-containing water, and/or ozone gas. Disinfected water may be produced by introducing ozone gas into a potable or purified water source for the purpose of disinfecting or controlling the microorganisms in the water source. Ozonated water or ozone gas may be produced and provided for various anti-microbial and cleansing applications of the consumer, such as washing food, clothing, dishes, countertops, toys, sinks, bathroom surfaces, and the like. Furthermore, the ozone generator may be used to deliver a stream of ozone-containing water for the purpose of commercial or residential point-of-use washing, disinfecting, and sterilizing medical instruments and medical equipment.

  • Patent number: 6387226
    Abstract: A device for treating water that circulates in a closed conduit system, said device comprising a combination of a degasifier, on the one hand, and a corrosion inhibitor, on the other hand. The degasifier includes a tubular member (10) which is horizontal in its use position and which is intended to be connected in series with a conduit (13, 14) forming part of the conduit system. The tubular member is surrounded between its upstream and downstream ends (11, 12) by a housing (17) which includes an openable upper gas outlet (16). The tubular member communicates with the surrounding housing space through the medium of at least one aperture (15) provided therein. The corrosion inhibitor includes a sacrificial anode (20) which is positioned in the housing space outside the tubular member (10). The housing (17) also includes an openable bottom drain or outlet (28).
