ION CONDUCTOR AND FUEL CELL

摘要

Disclosed is a fuel cell which is capable of having good characteristics such as power density, while being highly safe. Specifically, ion conductor serving as a first fluid (F1) containing an electrolyte is passed through an electrolyte path (30) which is arranged between a fuel electrode (10) and an oxygen electrode (20). The ion conductor is obtained by dissolving an organic compound, which is in a solid state at room temperature and has at least one of a sulfonic acid group and a phosphonic acid group, into a solvent. Consequently, the resistance between the fuel electrode (10) and the oxygen electrode (20) can be suppressed low. When the solvent has evaporated due to environmental changes, the organic compound remains as a solid, thereby preventing corrosion of the surrounding members.
