Abstract
An electrode includes a first diffusion layer (11) having water repellency and functioning to diffuse oxygen, and a second diffusion layer (13) supporting a catalyst layer (30) thereon and functioning to diffuse oxygen. The electrode further includes an electrically conductive layer (12, 15) including a metal material (20, 21) and an oxygen-permeable material, and interposed between the first diffusion layer and the second diffusion layer. A fuel cell (100) and a water treatment equipment each include: an anode (3); an ion transfer layer (4) having proton permeability; and a cathode (1, 2) being the electrode described above, and separated from the anode with the ion transfer layer interposed therebetween.
