摘要： A wire showing satisfactory electrical insulation, mechanical strength, wear resistance, crosslinking properties and appearance may be obtained by coating a conductor with an ethylene/&agr;-olefin copolymer whose density, melt flow rate, decane soluble matter content, melting point and melt tension are controlled to particular ranges. The copolymer may be used singly or in combination with high-pressure low-density polyethylene. Such copolymer provides a coated layer showing tensile strength of not less than 15 MPa, tensile elongation of not less than 400% and taper wear amount of not more than 15 mg. Furthermore, if the resin pressure in the extruder is adjusted to a particular range, high-speed extrusion becomes possible with a smooth apparent coated layer.

摘要： In order to provide a membrane electrode assembly that can further improve power generation performances of a fuel cell, the present invention allows a rib portion (22) that separates mutually adjacent gas flow passages (21) from each other to have a porosity lower than the porosity of a lower area (23) of the rib portion. Thus, it is possible to suppress the deformation of the rib portion and excessive permeation of a reaction gas, and consequently to further improve the power generation performances.
