    摘要： A method for producing a catalyst-coated membrane includes: preparing and/or providing a first ink having a first ink composition, comprising substrated catalyst particles proton-conducting ionomer and dispersing agent, in which the fraction of the substrated catalyst particles remains behind the fraction of the proton-conducting ionomer; preparing and/or providing at least one second ink having a second ink composition, comprising the substrated catalyst particles, the proton-conducting ionomer and the dispersing agent, in which the fraction of the proton-conducting ionomer remains behind the fraction of the substrated catalyst particles, unwinding a weblike proton-conducting membrane material provided on a roll; applying at least one layer of the first ink with a first application tool onto at least one section of the membrane material; and applying at least one layer of the second ink with a second application tool onto an outermost layer of the first ink deposited onto the membrane material

    摘要： Disclosed are a polymer electrolyte membrane and a membrane-electrode assembly comprising same, the membrane having, without a deterioration in performance such as ion conductivity, excellent mechanical properties, so as to ensure the manufacture of a membrane-electrode assembly having such high durability that the wet/dry cycle, which is measured according to accelerated durability test method of a NEDO protocol, is 30,000 times or more. The polymer electrolyte membrane of the present invention comprises: a porous support having a plurality of pores; and a composite layer including ionomers that fill the pores, wherein the ratio (IS/FS) of the stab initial strain (IS) of the polymer electrolyte membrane to the stab final strain (FS) of the polymer electrolyte membrane is 0.4 to 1.0.
