摘要：
A laminated catalyst according to an embodiment includes an oxide layer, a first catalyst layer on the oxide layer and a second catalyst layer on the first catalyst layer. The oxide layer is a layer of oxide including one or more non-noble metals as a main component. The first catalyst layer includes an oxide of noble metal including Ir and/or Ru as a main component. The second catalyst layer includes an oxide of noble metal including Ir and/or Ru as a main component. The first catalyst layer is denser than the second catalyst layer.
