摘要： The present invention relates to a method for producing a polymer electrolyte molded article, which comprises forming a polymer electrolyte precursor having a protective group and an ionic group, and deprotecting at least a portion of protective groups contained in the resulting molded article to obtain a polymer electrolyte molded article. According to the present invention, it is possible to obtain a polymer electrolyte material and a polymer electrolyte molded article, which are excellent in proton conductivity and are also excellent in fuel barrier properties, mechanical strength, physical durability, resistance to hot water, resistance to hot methanol, processability and chemical stability. A polymer electrolyte fuel cell using a polymer electrolyte membrane, polymer electrolyte parts or a membrane electrode assembly can achieve high output, high energy density and long-term durability.

摘要： A prepreg includes; sizing agent-coated carbon fibers coated with a sizing agent; and a thermosetting resin composition impregnated into the sizing agent-coated carbon fibers. The sizing agent includes an aliphatic epoxy compound (A) and an aromatic compound (B) at least containing an aromatic epoxy compound (B1). The thermosetting resin composition includes a thermosetting resin (D) and a latent hardener (E), and optionally includes an additive (F) other than the thermosetting resin (D) and the latent hardener (E). The (a)/(b) ratio is within a predetermined range where (a) is the height of a component at a binding energy assigned to CHx, C—C, and C═C and (b) is the height of a component at a binding energy assigned to C—O in a C1s core spectrum of the surfaces of the sizing agent-coated carbon fibers analyzed by X-ray photoelectron spectroscopy.
