摘要:
An electrocatalyst for an electrode comprises (i) an electrically conductive particulate support comprising one or more electrocatalytically active metals and (ii) an electrically conductive material which is substantially free of electrocatalytically active metals and has an electroconductivity which is higher than the electroconductivity of (i). This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
摘要:
A solid fuel composition which is suitable for preparing a liquid fuel for a direct liquid fuel cell. The composition comprises at least one solid hydride compound selected from borohydrides, aluminum hydrides, and metal hydrides, and at least one alkaline compound selected from hydroxides of alkali and alkaline earth metals, Zn, Al, and ammonium. If placed in a direct liquid fuel cell and contacted with an aqueous liquid the composition dissolves gradually as the at least one hydride compound is consumed while the fuel cell is in operation. This Abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

摘要:
A power supply system, in particular for use during emergencies and/or power outages, that includes at least one liquid fuel cell, at least one cartridge, and a system or device for transferring the contents of the cartridge to the fuel cell. A cartridge-free power supply system is also disclosed. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
摘要:
Described is a leak-proof fuel cell which comprises at least one liquid within a casing that comprises at least one opening which is sealed by a first structure that is gas-pervious and substantially impervious to the at least one liquid. At least that portion of the casing which comprises the at least one opening is enclosed by a second structure which allows gas to pass therethrough. A space defined by the casing and the second structure comprising therein at least one material that is capable of binding the at least one liquid. This Abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
摘要:

摘要:
A method of producing a fuel or concentrate thereof for a fuel cell. The method comprises providing a solution of at least one hydroxide ion providing compound in a liquid medium and combining and mixing one or more hydride compounds with this solution to provide a colloidal dispersion of the hydride compound(s) in the alkaline medium. This Abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
摘要:
A hydride containing fuel composition for a liquid fuel cell. The composition comprises an alkaline liquid phase and at least two hydride compounds. The solubility of the first hydride compound in the liquid phase is higher than the solubility of a second hydride compound in the liquid phase and the opposite is true for the anodic oxidation products thereof. This Abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
摘要:
A method of preparing an electroconductive foam, and the foam so prepared. An electroconductive polymer such as polyaniline is dispersed in a liquid medium that includes an aromatic solvent such as xylene and an organic dopant/dispersant such as an aromatic sulfonic acid. The electroconductive polymer together with the organic dopant/dispersant constitute between 10% and 25% of the resulting dispersion. The dispersion is introduced to the pores of an electrically insulating foam matrix such as polyurethane. Excess dispersion is expelled and the foam is dried actively, to line the pores with an electroconductive lining.
