    摘要： The present invention provides a self-replenishing liquid water source onboard an automobile for supplying liquid water to an electrolyzer, such as an on-board hydrogen generator useful for the suppression of unwanted emissions. While automobiles typically have water reservoirs resupplied by a person, the invention provides a passive means of water collection for reliable replenishment due to operations of the automobile itself. The invention provides condensate from the engine exhaust gas by cooling a region of the exhaust system using cooling fluid from the engine coolant system. The cooling fluid is circulated during a period following the engine cold start event when the heat load on the engine coolant system is low.

    摘要： The present invention provides an apparatus and method for assembling an electrochemical cell stack, or an assemblage of components which need to be clamped together, especially where minimizing the size and weight of the clamping mechanism is advantageous. The invention encompasses combining a band or strap to transmit load to a plurality of components. A metal link is provided to apply greater tension to the band than could normally be achieved with the band alone. The invention may provide a band having a spiral screw clamp wherein the screw portion is used to apply and control tension in the band and the band is used to transmit the tension to a plurality of components. The invention also provides systems that improve the distribution of the force over a portion of the assembly, preferably the entire area of at least one face of the assembly. The invention encompasses a system with straps surrounding a fuel cell stack placed between two end plates, with raised ridges placed under the strapping system to concentrate the compressive force at selected points on the endplates. The invention also encompasses a device comprising an array of adjustable elements that control the distribution of the compressive load.

    摘要： This invention is an improved fuel cell design for use at low pressure. The invention has a reduced number of component parts to reduce fabrication costs, as well as a simpler design that permits the size of the system to be reduced at the same time as performance is being improved. In the present design, an adjacent anode and cathode pair are fabricated using a common conductive element, with that conductive element serving to conduct the current from one cell to the adjacent one. This produces a small and simple system suitable for operating with gas fuels or alternatively directly with liquid fuels, such as methanol, dimethoxymethane, or trimethoxymethane. The use of these liquid fuels permits the storage of more energy in less volume while at the same time eliminating the need for handling compressed gases which further simplifies the fuel cell system. The electrical power output of the design of this invention can be further increased by adding a passage for cooling the stack through contact with a coolant.

    摘要： This invention is a novel method for bioremediation of soil and ground water based on supplying hydrogen (H2) to naturally occurring anaerobic bacteria in the soil or ground water. These organisms use the hydrogen as an electron donor to perform adventitious chemical reactions including the dehalogenation of chlorinated organic compounds. The hydrogen can be supplied from a number of sources, including; stored hydrogen, hydrogen generated above ground on site, either electrochemically or by reforming a fuel source, or by electrolysis in the soil, either using an electric current supplied from above ground or an electric current generated by the corrosion of metal particles in the ground. For the last of these cases, a novel multi-metallic particle especially useful for the generation of hydrogen, and a method for making these particles, are disclosed.
