Embodiment

[0082] Hereinafter, the present invention will be described more specifically with reference to production examples, examples, and comparative examples, but the present invention is not limited to the following examples. In addition, the materials used in the following Examples are as follows.

[0083] ·Natural graphite: average particle size 25μm

[0084] ·PAN-based carbon fiber: average fiber length 3.0mm, average fiber diameter 7μm

[0085] · Poly-p-phenylene terephthalamide fiber: average fiber length 0.9mm, average fiber diameter 10μm, decomposition temperature 500°C

[0086] [1] Production of conductive sheet

manufacture example 1

[0088] 87 parts by mass of natural graphite, 3 parts by mass of PAN-based carbon fiber, and 10 parts by mass of aramid fiber were put into water and stirred to obtain a fibrous slurry. Papermaking was performed on this slurry, and the electroconductive sheet A was produced. The basis weight of conductive sheet A is 78g / m 2 .

[0089] [2] Preparation of resin solution

manufacture example 2

[0091] 71.8 parts by mass of NC-3000 (Nippon Kayaku Co., Ltd.) as an epoxy resin, 27.9 parts by mass of Fenolite (registered trademark) TD2090 (registered trademark) as a curing agent, and キュアゾール (registered trademark) as a curing accelerator 0.3 parts by mass of trademark) 2PZ (Shikoku Chemical Industry Co., Ltd.) was dissolved in 100 parts by mass of acetone to prepare a 50% by mass resin solution A.

Abstract

The present invention provides a conductive metal resin multilayer body that comprises: a metal foil; and a resin layer which is arranged on at least one surface of the metal foil, and which contains a resin, organic fibers and a conductive filler that is formed of a non-metal material.

Description

technical field [0001] The present invention relates to a conductive metal-resin laminate and a molded body thereof. Background technique [0002] The fuel cell separator (separator) functions as a boundary wall that separates the unit cells, in addition to providing electrical conductivity to the unit cells and securing passages for fuel and air (oxygen) supplied to the unit cells. Therefore, separators are required to have various properties such as high electrical conductivity, high gas-impermeability, chemical stability, heat resistance, and hydrophilicity. [0003] Fuel cell separators are largely classified into carbon separators formed of carbon-based materials and metal separators formed of metal materials. Among them, the metal separator has high electrical conductivity, high heat transfer, mechanical strength and gas impermeability. However, metal separators have the disadvantage of being susceptible to corrosion caused by the environment in the fuel cell. [00...
