20110244366 | ION CONDUCTOR AND FUEL CELL - There is provided a fuel cell capable of ensuring high safety, and capable of obtaining favorable characteristics such as power density. As a first fluid containing an electrolyte, an ion conductor in which an organic compound which is solid at a room temperature and which has at least one of a sulfonic acid group and a phosphoinic acid group is dissolved in a solvent flows through an electrolyte path arranged between a fuel electrode and an oxygen electrode. Thereby, it is possible to suppress resistance between the fuel electrode and the oxygen electrode low. Also, in the case where the solvent is evaporated due to an environmental change, since that organic compound remains as solid, a surrounding member is unlikely to be corroded. | 10-06-2011 |
