Abstract: A hydrogen storage alloy is provided which has an extremely low Co content, and can maintain the drain (power) performance (especially pulse discharge characteristics), activity (degree of activity), and life performance at high levels. The hydrogen storage alloy is manufactured by weighing and mixing every material for the hydrogen storage alloy so as to provide an alloy composition represented by the general formula MmNiaMnbAlcCod or MmNiaMnbAlcCodFee, and controlling the manufacturing method and manufacturing conditions so that both the a-axis length and the c-axis length of the crystal lattice are in a predetermined range. Although it is sufficient if the a-axis length of the crystal lattice is 499 pm or more and the c-axis length is 405 pm or more, by further specifying the a-axis length and c-axis length depending on the values of ABx, a hydrogen storage alloy having high durability can be provided.

Abstract: Provided is a palladium catalyst in which palladium (Pd) is used as a catalyst active component, and particularly a novel palladium catalyst which can purify CO and THC with high efficiency even under a fuel-rich atmosphere having a high space velocity (SV). Proposed is a palladium catalyst having a substrate and a catalyst layer that contains palladium acting as a catalyst active component, an inorganic porous material acting as a catalyst support and ceria (CeO2) particles acting as a promoter component, in which a mass ratio (Pd/CeO2) of a content of the palladium in the catalyst layer to a content of the ceria particles in the catalyst layer is 0.0014 to 0.6000.
