Abstract: An electrode structure has a pair of electrode catalyst layers and a polymer electrolyte film held between the electrode catalyst layers. The polymer electrolyte film contains 5 weight% of coordinated water of proton of a sulfonic acid group and composed of a fluorine−containing ion−conductive polymer. The content of fluorine in the polymer electrolyte film to the electrode catalyst layer lies in the range from 0.2 to 2.0. The polymer electrolyte film is composed of a sulfonate of a copolymer of repeating units expressed by formulae (1) and (2). The electrode catalyst layer contains platinum at 0.01 to 0.8 mg/cm 2 , and the average particle diameter of carbon particles of the carrier lies in the range from 10 to 100 nm. The polymer electrolyte film is made from a solution of the sulfonate and dried. The film contains 3 to 15 weight% of the solvent after dried. The electrode structure is completed by applying to it a current of 0.1 A/cm 2 or more in the humidified environment of a relative humidity of 60% or more for five hours or more. The electrode structure constitutes a fuel cell that generates power when an oxidizing gas is supplied to one side and a reducing gas is supplied to the other side.

Abstract: Disclosed is an electrode electrolyte for use in a solid polymer fuel cell or the like. A solid polymer fuel cell has a pair of electrodes on both sides of a proton-conductive solid polymer electrolyte film and can generate electricity by feeding a fuel gas (e.g., pure hydrogen) to one electrode and feeding an oxidizing agent (e.g., air) to the other electrode, in which the electrodes are composed of an electrode electrolyte having an electrode catalytic component (e.g., platinum) dispersed therein. In a conventional solid polymer fuel cell, a perfluoroalkylsulfonate polymer has been used as the electrode electrolyte. This material has excellent proton conductivity, but is very expensive. Further, because of a large amount of fluorine atoms present in the molecule, the material is poor in combustion property and therefore makes it difficult to collect or recycle platinum or the like used in the electrode electrolyte. These problems can be overcome by using an electrode electrolyte which comprises a polymer having a polyphenylene backbone and a side chain having a sulfonate group and a side chain having a nitrogenated heterocyclic group or the like.
Abstract translation: 公开了一种用于固体聚合物燃料电池等的电极电解质。 固体聚合物燃料电池在质子传导性固体聚合物电解质膜的两侧具有一对电极，并且可以通过将一种燃料气体（例如纯氢）供给一个电极并且供给氧化剂（例如空气）来发电， 到另一个电极，其中电极由分散在其中的电极催化组分（例如，铂）的电极电解质组成。 在常规的固体聚合物燃料电池中，已经使用全氟烷基磺酸盐聚合物作为电极电解质。 该材料具有优异的质子传导性，但是非常昂贵。 此外，由于分子中存在大量的氟原子，所以材料的燃烧性能差，因此难以收集或回收在电极电解质中使用的铂等。 通过使用包含具有聚亚苯基主链和具有磺酸基的侧链的聚合物和具有氮杂环基等的侧链的聚合物，可以克服这些问题。

Alternatively, when the number of the groups capable of being sulfonated contained in the main chain of that polymer, that of the divalent aromatic residues contained in the main chain and undergoing no sulfonation, and that of the oxy groups contained in the main chain are indicated by A, B, and C, respectively, then (B/C)x(B+C)−A is in the range of from 35 to 380.
