    摘要: A membrane electrode assembly according to the invention includes a solid polymer electrolyte membrane and an electrode joined to each of two sides of the solid polymer electrolyte membrane. The solid polymer electrolyte membrane is such that some or all of the protons included in the entire solid polymer electrolyte membrane, a band region, or a non-power generating region are ion exchanged with one or more cations selected from among complex cations, class four alkylammonium cations, and high valence cations. In addition or alternatively, the solid polymer electrolyte membrane includes an organo-metalloxane polymer obtained by impregnating the entire solid polymer electrolyte membrane, the non-power generating region, or the band region with an organo-metalloxane monomer that includes an ammonium cation or a class four ammonium cation at its terminus and then hydrolyzing and polycondensing the organo-metalloxane monomer.

    摘要: In a method of brazing aluminum material, the flux is formed on the surface of the aluminum material by a chemical conversion coating step. The aluminum material is brought into contact with a treating solution containing potassium and fluorine ions to cause a chemical reaction between aluminum components and potassium and fluorine ions, thereby forming K.sub.2 AlF.sub.5. The K.sub.2 AlF.sub.5 is present on the surface of the aluminum material as a uniform coating and acts as the flux during brazing. With the treating solution further containing zinc, the flux of K.sub.2 AlF.sub.5 and a pitting corrosion inhibiting layer of metallic zinc are simultaneously formed. The treating solution may further include powdered K.sub.2 AlF.sub.5 or AlF.sub.3 to increase the amount of flux and thus to intensify the action of the flux. The chemical conversion coating may be applied either to the material to be brazed or to the material for brazing.
