    摘要： According to one embodiment, there is provided a catalyst layer containing a catalyst material. The catalyst layer satisfying requirements below: a porosity of 20 to 90% by vol; and a relation R1≧R0×1.2. In the above inequality, R1 represents an alignment ratio of the catalyst layer and R0 represents an alignment ratio of the catalyst material in powder form having a random crystalline plane distribution, and each of the alignment ratios is calculated from a X-ray diffraction spectrum having a diffraction angle 2θ range from 10 to 90 degree measured using Cu-Kα-rays.
