CARBON MEMBER, CARBON MEMBER MANUFACTURING METHOD, REDOX FLOW BATTERY AND FUEL CELL

摘要

This carbon member can be optimally used as the battery member of a redox flow battery or fuel cell, and is characterized by being formed into a single body by welding together: a first layer which contains 100 parts by mass of a first resin composition containing a polyolefin resin and having a melt flow rate of 0.01-10g/10min, and 100-1000 parts by mass of a first carbonaceous material; a second layer which contains 100 parts by mass of a second resin composition containing a polyolefin resin, having a melt flow rate of 5-1000g/10min and higher than that of the first resin composition and having a melting point of 80°C or greater and at least 10°C lower than that of the first resin composition, and 100-1000 parts by mass of a second carbonaceous material; and a third layer which is arranged opposite of the first layer with the second layer interposed therebetween and which comprises a porous carbon material with a bulk density of 60-800kg/m3.
