摘要： In one example embodiment, an electronic device uses a fuel cell which reduces thickness of the overall fuel cell while reducing electrical resistance. In one example embodiment, a flow path that distributes an electrolyte is included between a fuel electrode and an oxygen electrode. In one example embodiment, a current collector on the fuel electrode side has a pair of current collector terminals in opposing-corner positions. Similarly, a current collector on the oxygen electrode side has a pair of current collector terminals in opposing-corner positions. The current collector terminals project outside the fuel cell. Thereby, connection of unit cells within the battery is facilitated, a monopolar plate structure becomes easier to use as the current collector, and distance of flowing current is shortened.

摘要： 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.
