Resin composition for fuel cell member

Abstract

There is provided a resin composition for a fuel cell member which givens only a small amount of eluting ions. A resin composition for a fuel cell member is formed to include 60 to 85 wt % of the following polypropylene and 40 to 15 wt % of the following talc: (1) polypropylene that is homopolypropylene, blockpolypropylene or a blend of homopolypropylene and blockpolypropylene, and has a melt flow rate of 2 to 40 g/10 min.; (2) talc that has a whiteness degree of 96% or more, and an average particle diameter of 4 to 10 μm.

1 . A resin composition for a fuel cell member comprising 60 to 85 wt % of the following polypropylene and 40 to 15 wt % of the following talc: 
 (1) polypropylene that is homopolypropylene, blockpolypropylene or a blend of homopolypropylene and blockpolypropylene, and has a melt flow rate of 2 to 40 g/10 min;    (2) talc that has a whiteness degree of 96% or more, and an average particle diameter of4 to 10 μm.    
     
     
         2 . The resin composition for a fuel cell member according to  claim 1 , 
 wherein the specific surface area of the talc is from 7 to 45 m 2 /g.    
     
     
         3 . The resin composition for a fuel cell member according to  claim 1 , 
 wherein when the total weight of the polypropylene and the talc is regarded as 100 parts by weight, 0.01 to 1 part by weight of carbon black is contained.    
     
     
         4 . The resin composition for a fuel cell member according to  claim 1 , of which the electric conductivity is 2 μS/cm or less.  
     
     
         5 . The resin composition for a fuel cell member according to  claim 1 , 
 wherein the fuel cell member is a fuel cell cooling circuit member, a fuel cell ion exchanging component, or a fuel cell ion exchanging cartridge.
