    摘要： The invention provides a process for efficient synthesis of ammonia. The process includes a water-splitting step in which water is decomposed to obtain a first source gas comprising hydrogen and oxygen, a first oxygen removal step in which the oxygen contained in the first source gas is at least partially separated and removed by an oxygen separating membrane or hydrogen separating membrane to obtain a second source gas having a lower oxygen concentration than the first source gas, a second oxygen removal step in which the oxygen in the second source gas is reacted with hydrogen to produce water for removal, or is adsorbed onto an adsorption medium for removal, to obtain a third source gas having a lower oxygen concentration than the second source gas, and an ammonia synthesis step in which the hydrogen in the third source gas is reacted with nitrogen to synthesize ammonia.

    摘要： A tubular fuel cell includes an inner current collector, a membrane-electrode assembly, and seal portions provided at the axial end portions of the membrane-electrode assembly, respectively. The membrane-electrode assembly includes an inner catalyst layer provided on the inner current collector, an electrolyte membrane provided on the inner catalyst layer, and an outer catalyst layer provided on the electrolyte membrane. The axial length of the outer catalyst layer is shorter than the axial lengths of the electrolyte membrane and the outer catalyst layer. The axial end face of the outer catalyst layer and the axial end face of the inner catalyst layer are located on the opposite sides of the seal portion in each side of the tubular fuel cell.

    摘要： The present invention provides a solid electrolyte with high ion-conductivity which is cheap and exhibits high conductivity in an alkaline form, and stably keeps high conductivity because of a small amount of the leak of a compound bearing conductivity even in a wet state. The invention is useful in an electrochemical system using the solid electrolyte, such as a fuel cell.The solid electrolyte with high ion-conductivity comprises a hybrid compound which contains at least polyvinyl alcohol and a zirconic acid compound, and also a nitrogen-containing organic compound having a structure of amine, quaternary ammonium compound and/or imine, obtained by hydrolyzing a zirconium salt or an oxyzirconium salt in a solution including water, polyvinyl alcohol, a zirconium salt or an oxyzirconium salt and a nitrogen-containing organic compound having a structure of amine, quaternary ammonium compound and/or imine coexist, removing a solvent and contacting with alkali.
