Abstract

A direct methanol type fuel cell is provided with a generated gas ejection part having a bundle made up of hollow fiber membranes extending between a fuel electrode and a liquid fuel vaporizing layer that vaporizes a methanol aqueous solution and supplies methanol gas to the fuel electrode. The hollow fiber membranes selectively pass carbon dioxide within a mixture gas that includes methanol, the carbon dioxide generated at the fuel electrode and the like, and eject the carbon dioxide via end portions of the hollow fiber membranes that open at a side surface of the fuel cell via hollow portions. The fuel cell has a high carbon dioxide ejection capability, and suppresses leak of methanol gas. A pressure applying part may be provided to apply a back pressure to the methanol aqueous solution within a fuel storage part, so as to further improve the carbon dioxide ejection capability.
