A solid porous rigid fuel composition for the generation of hydrogen gas by the reaction of a liquid hydroxide solution with the solid fuel, the fuel composition comprising siliconcontaining metal particles, such as ferrosilicon, and a powdered salt compound, such as an alkali metal halide like sodium chloride, the metal silicon particles bonded together into a rigid porous mass, and the salt compound present within the porous mass to inhibit the formation of slow dissolving silicate cement on the surface of the silicon metal particles on repeated reaction of the silicon particles with a liquid hydroxide solution. |
