    摘要： The catalyzed method of this invention features a method for operating an electrical automotive vehicle. The method of the invention utilizes a hydrogen-air fuel cell to power an electrical automotive vehicle having electrical drive motors. Hydrogen to fuel the fuel cell is supplied onboard by a bed of iron that is made to react with H.sub.2 O in the presence of an alkaline catalyst at temperatures not exceeding approximately 250.degree. C. The preferred alkali hydroxide is the hydroxide of potassium in a range of concentrations between 50 to 60 percent by weight, with the preferred concentration being about 53%. The hydrogen for fueling the fuel cell is generated onboard the automobile, in situ, by using a storage compartment containing iron materials. The hydrogen is generated by passing heated water over freshly ground iron, which then becomes iron oxide. The vehicle's operator obtains a fresh charge of the new iron materials from an iron fuel station for placement in a compartment of the vehicle. The iron materials of this invention may comprise in situ freshly-ground particulates. The particles range in diameter size from approximately 25 to 1,200 .mu.m, with an average-sized distribution having at least twenty per cent (20%) of the particles less than 300 .mu.m in diameter. It is preferable that at least 50% are less than 300 .mu.m in diameter. The average particle density ranges approximately from about 1 to 7.8 g/cc, with a non-compressed packed particle density ranging from about 1.5 to 3.5 g/cc. The particles have a surface area greater than approximately 0.001 meters.sup.2 /g.

    摘要： Decomposition of water to hydrogen and oxygen with the aid of a thermochemical cyclic process based upon the iron/chlorine system by reduction of FeCl.sub.2 in the presence of H.sub.2 to Fe, oxidation of the Fe with steam to Fe.sub.3 O.sub.4, treatment of the hot Fe.sub.3 O.sub.4 with steam and chlorine to obtain oxygen, conversion of themixture of iron oxides so obtained with hydrogen chloride to FeCl.sub.2 and recycling of the FeCl.sub.2 to the reduction stage, wherein a part of the heat required for the process is supplied by heating the hydrogen and steam in indirect heat exchange with a hot coolant from a high temperature nuclear reactor. The conversion of the iron oxides to FeCl.sub.2 is carried out via the intermediate stage of dimeric FeCl.sub.3 and it is thus possible to convey the solid reaction products by free fall through the reaction zones.

    摘要： A process for the dissociation of water into hydrogen and oxygen in a multi-stage closed cycle process using a system involving at least one metallic element having multiple valency and at least one halogen, characterized in that a halide of the multiple valency metallic element is subjected to a mixture of steam and hydrogen converting the halide to a mixture of the metallic element and at least one oxide thereof, said latter mixture is subjected to steam to produce a mixed valency oxide of the metallic element accompanied by the liberation of hydrogen, and said mixed valency oxide is then subjected to a hydrogen halide to convert it back to the said metallic halide with the liberation of oxygen.
