    摘要: Components for the manufacture of polymer electrolyte membrane fuel cells are provided, as well as apparatus and automatable methods for their manufacture by rotary die cutting and by lamination of various layers to form membrane electrode assemblies. A method and apparatus for performing the method are provided comprising die-cutting webs of catalyst decal materials or electrode materials to make first and second workpieces at first and second rotary die stations; holding the die-cut workpieces by action of sub-ambient air pressure to an endless perforated belt of first and second vacuum conveyors, typically before they are fully cut from the first and second webs; transporting first and second workpieces to opposing sides of a membrane in a laminating station; concurrently feeding the first and second workpieces into the laminating nip adjacent to the membrane, and laminating the first and second workpieces to the membrane.

    摘要: A membrane electrode assembly for a fuel cell, a method of preparing the same, and a fuel cell using the membrane electrode assembly for a fuel cell. The membrane electrode assembly includes an anode comprising an anode substrate, an anode diffusion layer, and an anode catalyst layer having pores; a cathode comprising a cathode substrate, a cathode diffusion layer, and a cathode catalyst layer having pores; and an electrolyte membrane interposed between the cathode and the anode, wherein the anode diffusion layer is hydrophilic and the cathode diffusion layer is hydrophobic, and the average diameter of the pores of the anode catalyst layer is smaller than the average diameter of the pores of the cathode catalyst layer. In the membrane electrode assembly, air can be easily supplied to the cathode and water can easily flow out of the cathode, thereby obtaining high performance of the membrane electrode assembly, and the anode catalyst layer has relatively small pores, thereby improving durability of the anode and reducing the diffusion speed of methanol in the anode catalyst layer to maintain the initial performance of a battery for a long time.

    摘要: A catalyst coated electrolyte membrane including an anode catalyst layer and a cathode catalyst layer at opposite sides thereof, respectively, wherein micro cracks of the anode catalyst layer or cathode catalyst layer occupy 0.01-1 area % of the total area of the respective anode catalyst layer or cathode catalyst layer, a fuel cell including the same, and a method of preparing the catalyst coated electrolyte membrane. In the catalyst coated electrolyte membrane, micro cracks of the cathode catalyst layer or the anode catalyst layer can be minimized and thus the resistance between the electrode catalyst layer and an electrolyte membrane can be minimized, and crossover of a fuel, such as methanol, ethanol, other alcohols, methane, etc., to a cathode electrode can be minimized, and thus the catalyst coated electrolyte membrane has improved performance and durability.
