SOLID POLYMER FUEL CELL

摘要

This invention provides a solid polymer fuel cell for gasifying and supplying an alcohol fuel, which can realize excellent power generation properties and storage properties. A fuel supply part (1) opposed to a fuel electrode (8) comprises a high-concentration fuel tank (3) and a water fuel tank (4) for storing water. The solid polymer fuel cell is characterized in that a fuel gasification/supply layer comprising pored plates (3d, 4d) and porous bodies having a gas-liquid separating properties (gasification/supply parts (3c, 4c) is provided between the fuel electrode (8) and the fuel tanks (3, 4), and a CO₂ gas discharge port (6) is provided besides the fuel electrode on the high-concentration fuel tank (3) side. The above simple structure can ensure necessary alcohol and water in the fuel tank during power generation and can realize stable power generation properties. Further, during the storage, excellent storage properties and starting properties can be realized by humidifying a power generation part (2) in such a state that only the water fuel tank (4) is opened.
