    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a hydrogen separator, capable of reducing the occurrence of pin holes in a hydrogen separation metal layer.SOLUTION: A method for manufacturing a hydrogen separator includes: a first step of mixing Pd being a hydrogen separation metal, or metal powder containing the Pd and a metal (e.g., Ag) alloyed with the Pd for improving a hydrogen permeability as the main component with ceramics (e.g., YSZ) powder to make past-like materials; a second step of forming a surface forming layer (77) on support molded body (73) by covering the surface of the porous support molded body (73) before sintering using the past-like materials; and a third step of co-firing the support molded body (73) with the surface forming layer (77), and performing the sintering thereof. Consequently, a porous medium (20) comprising the hydrogen separation metal layer (19) inside is made.
    • 要解决的问题:提供一种能够减少氢分离金属层中的针孔的发生的氢分离器的制造方法。解决方案:氢分离器的制造方法包括:将作为氢的Pd 分离金属或包含Pd的金属粉末和与Pd合金化的金属(例如,Ag),以提高渗透性作为主要成分的陶瓷(例如YSZ)粉末以制造过去的材料; 第二步骤,在使用过去的材料烧结之前,通过覆盖多孔支撑成型体(73)的表面,在支撑成型体(73)上形成表面形成层(77) 以及将所述支撑成型体(73)与所述表面形成层(77)共烧的第三工序,进行烧结。 因此,制成内部包含氢分离金属层(19)的多孔介质(20)。
