Abstract: A carbon member for use as a battery member of a redox flow battery or a fuel cell, obtained by welding, into a single integrated body: a first layer including a first resin composition containing a polyolefin-based resin and having a melt flow rate of 0.01 to 10 g/10 min, and a first carbonaceous material; a second layer including a second resin composition containing a polyolefin-based resin, having a melt flow rate of 5 to 1,000 g/10 min that is greater than that of the first resin composition, and having a melting point that is 80° C. or higher, but is at least 10° C. lower than that of the first resin composition, and a second carbonaceous material; and a third layer, which is disposed facing the first layer with the second layer interposed therebetween, and is formed from a porous carbon material having a specified bulk density.

Abstract: This fluorine-containing ether compound is a fluorine-containing ether compound represented by formula (1). R1—X—R2—CH2—R3—CH2—R4  (1) (In formula (1), R1 is an alkenyloxy group of 2 to 8 carbon atoms or an alkynyloxy group of 3 to 8 carbon atoms. R2 is represented by formula (2) shown below. In formula (2), a represents an integer of 1 to 3. X is represented by formula (3) shown below. In formula (3), b represents an integer of 1 to 5, Y is a divalent linking group that is bonded to a carbon atom in formula (2), and R represents an alkyl group of 1 to 6 carbon atoms or H. R3 represents a perfluoropolyether chain. R4 represents a terminal group containing two or three polar groups, wherein each polar group is bonded to a different carbon atom, and the carbon atoms to which the polar groups are bonded are bonded to each other via a linking group containing a carbon atom to which a polar group is not bonded.)
