    • An ammonium gas sensor is provided. The ammonium gas sensor includes: a solid electrolyte layer having oxygen ion conductivity; a detection electrode formed on one surface of the solid electrolyte layer; a reference electrode that is a counter electrode of the detection electrode; a selective reaction layer covering the detection electrode; and a protection layer covering the selective reaction layer and made from a porous material; wherein the detection electrode includes a noble metal as a main component; the selective reaction layer includes oxide represented by AxMyOz as a main component, where A is one or more kind(s) of metal, M is vanadium, tungsten, or molybdenum and x, y, z are atomic ratios; and the protection layer includes the oxide that is in an amount smaller than a content of the oxide included in the selective reaction layer.
    • 提供了一种铵气体传感器。 铵气体传感器包括:具有氧离子传导性的固体电解质层; 形成在所述固体电解质层的一个表面上的检测电极; 作为检测电极的对电极的参考电极; 覆盖检测电极的选择性反应层; 以及覆盖选择性反应层并由多孔材料制成的保护层; 其中所述检测电极包括贵金属作为主要成分; 选择性反应层包括由AxMyOz表示的氧化物作为主要成分,其中A是一种或多种金属,M是钒,钨或钼,x,y,z是原子比; 并且保护层包括的量小于选择性反应层中包含的氧化物的含量的氧化物。
