PROBLEM TO BE SOLVED: To provide a solid polymer fuel cell, a liquid fuel cell, and an electrode, having high safety in a product or in a manufacturing process, low dispersion in the coating amounts in the manufacturing process, low coating defect, low cost, and high discharge performance by optimizing a surfactant used to enhance water repellent molecular weight or dispersion property of a binder in the electrode for the fuel cell. SOLUTION: The fuel cell is equipped with a hydrogen ion conductive polymer electrolyte membrane; a pair of electrodes prepared by stacking a catalyst layer coming in contact with the hydrogen ion conductive polymer electrolyte membrane and a gas diffusion electrode coming in contact with the catalyst layer; and a pair of separators having gas passages for supplying and exhausting fuel gas to and from one electrode and for supplying and exhausting oxidizing gas to and from the other electrode. A surfactant containing no endocrine disrupting chemicals is used in at least one of the electrodes. |
