摘要： A catalyst of an embodiment includes a porous structure including aggregates of particles containing Ru and metal atoms M different from Ru. The particles are a metal oxide. A metal atom ratio of the metal atom M in a surface region of the porous structure is higher than that of the metal atom M in the porous structure as a whole.

摘要： A membrane electrode assembly includes a pair of electrodes, each having a feeder layer that is porous and made of a conductive material, and an electrolyte membrane disposed between the pair of electrodes. At least one of the electrodes has a catalyst layer disposed in the feeder layer. In a cross section of the feeder layer, an electrolyte exists in a first region less than or equal to 80% of a thickness of the feeder layer from the electrolyte membrane toward an opposite direction to the electrolyte membrane, the catalyst layer exists at 50% or more of an outer circumference of a cross section of the conductive material in the first region, and the catalyst layer exists at 10% or less of the outer circumference of the cross section of the conductive material in a second region other than the first region.

摘要： A catalyst laminate includes a plurality of catalyst layers containing at least one of a noble metal and an oxide of the noble metal and at least one of a non-noble metal and an oxide of the non-noble metal, including: two or more first catalyst layers and two or more second catalyst layers. In an atomic percent of the noble metal obtained by using a line analysis by energy dispersive X-ray spectroscopy in a thickness direction of the catalyst laminate. The first catalyst layer is less than an average of a highest value and a lowest value of the atomic percent of the noble metal. The second catalyst layer has an atomic percent of the noble metal equal to or greater than the average of the highest value and the lowest value thereof. The second catalyst layer is present between the first catalyst layers.
