Abstract:
A catalyst layer containing a catalyst material, the catalyst layer having a porosity of 20 to 90% by vol and satisfying a relation: R1≧R0×1.2, wherein R1 is an alignment ratio of the catalyst layer; and R0 is 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.
