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.
