Abstract: 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.

Abstract: 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.
