    摘要: To provide a polymer electrolyte membrane that has excellent proton conductivity even under low-humidification conditions, has excellent mechanical strength and chemical stability, and can achieve high output and excellent physical durability when made into a polymer electrolyte fuel cell.The polymer electrolyte membrane includes a block copolymer containing each one or more of: a segment (A1) containing anionic group; and a segment (A2) not containing an ionic group. The polymer electrolyte membrane forms a co-continuous (M1) or lamellar phase-separated (M2) structure, and gives a crystallization heat quantity of 0.1 J/g or larger determined by differential scanning calorimetry, or a degree of crystallinity of 0.5% or larger determined by wide-angle X-ray diffractometry.

    摘要: In one aspect, a method of forming an electrode for an electrochemical device is disclosed. In one embodiment, the method includes the steps of mixing at least a first amount of a catalyst and a second amount of an ionomer or uncharged polymer to form a solution and delivering the solution into a metallic needle having a needle tip. The method further includes the steps of applying a voltage between the needle tip and a collector substrate positioned at a distance from the needle tip, and extruding the solution from the needle tip at a flow rate such as to generate electrospun fibers and deposit the generated fibers on the collector substrate to form a mat with a porous network of fibers. Each fiber in the porous network of the mat has distributed particles of the catalyst. The method also includes the step of pressing the mat onto a membrane.
