A fuel composition for fuel cells includes a polar solvent such as water, a first portion of a first fuel dissolved in the solvent at a saturated concentration, and a second portion of the first fuel suspended in the solvent to serve as a reservoir of fuel as the dissolved portion is consumed. Preferably, the first ...

A direct liquid fuel cell (1) includes a cathode (4), an anode (3), a fuel chamber (2), and at least one membrane (8) arranged between the anode (3) and the fuel chamber (2). The membrane (8) is structured and arranged to allow gas which is formed on or in the vicinity of the surface of the anode (3) which faces the...

An anode (3) for a liquid fuel cell (1) which has been subjected to a hydrophilization treatment in at least a part of a side (a) thereof that is intended to contact the liquid fuel.

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...

A storage-stable liquid concentrate for use with a fuel cell. The concentrate comprises at least one metal hydride compound, a solvent comprising one or more polar solvent components, and at least one hydroxide ion providing compound. Following a storage of the concentrate for 4 weeks at about 25 °C not more than ab...

Disposable fuel cell (10) and a system (20) for filling a disposable fuel cell. The fuel cell (10) has at least one chamber (EC, FC) a cartridge (20) having at least one chamber (CEC, CFC), and a valve system (6, 22) which regulates or controls fluid flow between the cartridge (20) and fuel cell (10). A method of re...

The present invention relates to a fuel composition for use in an electrochemical fuel cell, comprising:(a) a primary fuel including at least one surface-active compound;(b) an auxiliary fuel including at least one hydrogen-containing inorganic compound with a high reduction p...
