A green body packed with the powder particles each having a small amount of the thermoplastic resin particles attached thereon is placed under a melting condition of the thermoplastic resin particles, the thermoplastic resin is melted and gathers around contact points (or proximal points) of the adjoining powder particles.

Abstract: A composite membrane that can be used as an electrolyte membrane of a fuel cell is produced from a resin material that contains at least polybenzimidazole and from a composite material that is produced from of hydrogen sulfate and heteropoly acid. The composite membrane has a basic structure of an aromatic hydrocarbon that does not contain fluorine and has good efficiency, even at a low doping level, so it can be used for the electrolyte membrane of a medium temperature dry fuel cell. Phosphoric acid is doped into the composite membrane. Characteristics of the relationship between output current density and output voltage for an electrolyte membrane that is made from the created composite membrane (a specimen 4) are better than for a specimen 8, in which the amount of phosphoric acid doping is equivalent.

Abstract: By using a composite material that is produced from an acid salt of an oxo acid compound and an azole compound, a proton conductor with good proton conductivity properties under medium temperature, non-humidified conditions may be achieved. The composite material may be produced by mechanical milling of the acid salt of the oxo acid compound and the azole compound using a planetary ball mill The structure of the composite material obtained by the mixing processing may be different from that of a mixture of the acid salt of the oxo acid compound and the azole compound. Therefore, it may be possible to produce the proton conductor that has good proton conductivity properties under medium temperature, non-humidified conditions with a simple method of mechanical mixing.
