    摘要: A fuel cell device for generation of electricity from a polar oxidizer liquid and a non-polar fuel fluid includes a cathode in contact with the polar oxidizer liquid; an anode in contact with the non-polar fuel fluid; and a separator for separating the polar oxidizer liquid from the non-polar fuel fluid. The separator is made from material that is lyophobic with respect to the oxidizer liquid, and has a plurality of apertures, which are appropriately sized and spaced to form a meniscus in each aperture. The meniscus forms a liquid heterointerface between the conductive polar oxidizer liquid and the non-polar fuel fluid providing a controlled contact surface for oxidation processes. The fuel side of the separator may be coated with a conductive material to form the anode, in electric contact with the perimeter of the meniscus, and the cathode may be formed on the oxidizer side of the separator.

    摘要: The present invention relates to a process for operating a regenerative fuel cell (RFC). The process involves circulating a first electrolyte (electrolyte 1) through the negative chamber of the cell and a second electrolyte (electrolyte 2) through the positive chamber of the cell. Electrolyte (1) contains sulfide during the discharge cycle of the cell. Electrolyte (2) contains bromine during the discharge cycle of the cell. Decreases in ph in the electrolyte are compensated by circulating a fraction of other electrolyte (1) or (2) through the positive chamber of an auxiliary cell. A fraction of electrolyte (2), which has been made free of bromine, is circulated in the negative chamber of the auxiliary cell.

The secondary cell has relatively high capacitance and can be manufactured at low cost. Moreover, it provides more stable chemical reactions and can therefore be stably charged/discharged with large current and without risk of explosion.

    摘要: Two co-catalysts selected from the transitional metals can be employed in proton exchange membrane fuel cells to catalyze a borohydride anolyte, such that diatomic hydrogen produced on the surface of a particle of a first catalyst is diffused to an adjacent surface of a particle of a second catalyst. At the second catalyst the diatomic hydrogen is catalyzed to produce hydrogen ions, which are employed as the mobile ion transported across the electrolyte concurrent with the generation of electrical current. The apparatus operates without the accumulation of hydrogen gas, except as adhered to the surface of the two catalysts.
