    摘要: This invention provides a binder for a fuel cell which has high adhesion, low methanol solubility, high methanol permeability and high proton conductivity, a composition for electrode formation, an electrode for a fuel cell, and a fuel cell using them. The binder is particularly suitable for a binder for a direct methanol type fuel cell which requires high proton conductivity.The binder for a fuel cell comprises a block copolymer which comprises a block having a repeating structural unit of a divalent aromatic group that contains a protonic acid group and a block having a repeating structural unit of a divalent aromatic group that does not contain a protonic acid group, and which has a glass transition temperature (Tg) of 180° C. or less. In particular, it is preferable that the block copolymer has an ion exchange group equivalent of from 200 to 1,000 g/mole and a weight retention ratio of 90% or more as measured by immersion in a 64 weight % aqueous methanol solution at 25° C. for 24 hours.

    摘要: A polyvinyl acetal resin varnish which is so low in stimulus property, toxicity, environment-polluting property, offensive odor, and inflammability that no problem is caused in practical use, and which is high in safety, low in viscosity, and thus favorable in workability, and an application of the polyvinyl acetal resin varnish are provided. As an organic solvent for dissolving the polyvinyl acetal resin, there is used a nonaqueous solvent, preferably carbonate ester, and more preferably a mixed solvent composed of cyclic carbonate ester and chain carbonate ester, into which the polyvinyl acetal resin is evenly dissolved regardless of its type, resulting in varnish which is high in safety and low in viscosity. Since the varnish has an action of gelling the organic solvent, the varnish can be used as a gelling agent in various applications.
