摘要:
A method for manufacturing a solid electrolyte membrane made from an electrolyte composition that shows low methanol cross-over and exhibits high proton conductivity. The method includes applying an electrolyte composition including an organic solvent and a perfluorocyclobutane-containing polymer having a specific structure onto a substrate, and then removing the solvent. High proton conductivity is provided by sulfonic acid groups connected to the benzene rings. Reduction of methanol crossover is realized by introduction of a rigid structure with aromatic rings, or a combination of a rigid structure with aromatic rings and a three-dimensional cross-linked structure.

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.
