Abstract
An electrode includes a base material, and a catalyst layer provided on the base material, the catalyst layer including a plurality of catalyst units having a porous structure. The catalyst layer has a first catalyst layer provided near the base material, the first catalyst layer including a plurality of the catalyst units dispersed at a first dispersion degree. The catalyst layer has a second catalyst layer provided above the first catalyst layer, the second catalyst layer including a plurality of the catalyst units dispersed at a second dispersion degree. The second dispersion degree is different from the first dispersion degree.
