BulletPoint1 : Carbon fiber papers consist of high purity carbon fibers bonded together using a porous carbon matrix. Delivered on rolls, this material is used in demandingelectrochemical applications including specialty batteries, fuel cells, and electrolyzers.
BulletPoint2 : Carbon fiber papers are unparalleled in their ability to meet the rigorous demands of electrochemical applications, including catalyst and microporous layer support,effective transport of gases and liquids, and conduction of heat and electricity in corrosive and high temperature environments.
BulletPoint3 : Substrates are critical components of fuel cell membrane electrode assemblies (MEAs). EP40 Gas Diffusion substrates are unparalleled in their ability to meet the rigorous demands of the fuel cell, including platinum catalyst and functional layer support, effective transport of gases and liquids, and conduction of heat and electricity.
BulletPoint4 : Moreover EP55 substrates are highly durable, both chemically and mechanically.
BulletPoint5 : Carbon Fiber Papers are used as gas diffusion substrates or electrode backings for fuel cell applications.

1. Raw carbon paper: that is, carbon paper substrate, which shows certain hydrophilicity or hydrophobicity
2. Hydrophilic carbon paper (not provided by the manufacturer): this type of carbon paper is not provided by the manufacturer. Generally speaking, the "hydrophilic carbon paper" is actually raw carbon paper. The hydrophilic carbon paper needs to be acidified to make its surface carry hydrophilic groups.
3. Hydrophobic carbon paper: it refers to PTFE treatment of raw carbon paper to make the raw carbon paper more hydrophobic. .
4. Hydrophobic microporous layer carbon paper: it refers to the PTFE hydrophobic treatment of raw carbon paper, and on this basis, the hydrophobic carbon paper is coated with a mixture of PTFE and carbon black (or graphite, etc.) to form a microporous layer on its surface. .
Therefore, in order to select the appropriate carbon paper, please distinguish different concepts of carbon paper.
