Title:
燃料電池
Document Type and Number:
Japanese Patent JP4751383
Kind Code:
B2
Abstract:
A direct methanol type fuel cell 10 is provided with a generated gas ejection part 50 having a bundle 51 made up of hollow fiber membranes 52 extending between a fuel electrode 23 and a liquid fuel vaporizing layer 43 that vaporizes a methanol aqueous solution and supplies methanol gas to the fuel electrode 23. The hollow fiber membranes 52 selectively pass carbon dioxide within a mixture gas that includes methanol, the carbon dioxide generated at the fuel electrode 23 and the like, and eject the carbon dioxide via end portions of the hollow fiber membranes 52 that open at a side surface of the fuel cell 10 via hollow portions. The fuel cell 10 as a high carbon dioxide ejection capability, and suppresses leak of methanol gas. A pressure applying part 45 may be provided to apply a back pressure to the methanol aqueous solution within a fuel storage part 42, so as to further improve the carbon dioxide ejection capability.
