Abstract:
(EN) Provided are: an alkali water electrolysis system that comprises at least an electrolyte cell and a gas-liquid separation tank, and that is characterized in that an inlet for flowing a mixture of gas and an electrolyte from the electrolyte cell into the gas-liquid separation tank is disposed at a position higher than the liquid surface of the electrolyte in the gas-liquid separation tank; a water electrolysis method; and a method for producing hydrogen.
(FR) L'invention concerne : un système d'électrolyse d'eau alcaline qui comprend au moins une cellule électrolytique et une cuve de séparation gaz-liquide et qui est caractérisé en ce qu'une entrée pour l'écoulement d'un mélange de gaz et d'un électrolyte de la cellule électrolytique dans la cuve de séparation gaz-liquide est disposée dans une position plus élevée que la surface liquide de l'électrolyte dans la cuve de séparation gaz-liquide; un procédé d'électrolyse de l'eau; et un procédé de production d'hydrogène.
(JA) 少なくとも電解槽と気液分離タンクとを有するアルカリ水電解システムであり、ガスと電解液との混合物を電解槽から気液分離タンクに流入させるための流入口が、気液分離タンク内の電解液の液面よりも高い位置に設置されている、ことを特徴とする、水電解システム、水電解方法、水素製造方法。
