More Information
Summary:A gas diffusion electrode (10) includes: a water-repellent layer (1) that is formed of a woven fabric or a nonwoven fabric and has water repellency; and an adhesive layer (2) laminated on one surface of the water-repellent layer. Moreover, the gas diffusion electrode includes a gas diffusion layer (3) laminated on a surface of the adhesive layer, the surface being opposite of the surface facing the water-repellent layer. Then, the adhesive layer is non-biodegradable, and is alkali-resistant. A microbial fuel cell (100) includes: a negative electrode (20) that supports microorganisms; an ion-permeable membrane (30) that allows permeation of hydrogen ions; and a positive electrode (40) including the gas diffusion electrode, the positive electrode being separated from the negative electrode via the ion-permeable membrane.
