Abstract

A catalyst layer-supporting substrate includes a substrate and a catalyst layer. The catalyst layer includes a catalyst material and pores. The catalyst layer is formed on the substrate. The catalyst material has a layer or wire shape. A half-value width of a main peak of the catalyst material, as determined from X-ray diffraction spectrum of the catalyst layer, is 1.5° or more. A porosity of the catalyst layer is 30% or more.
