Abstract
A porous surface layer formed on a surface of a porous transport layer (PTL) includes carbon particles between 95% and 100% by weight of the porous surface layer. The porous surface layer is functionalized to control a degree of hydrophobicity or hydrophilicity and has a contact angle between 0° and 150°.

A porous surface layer formed on a surface of a porous transport layer (PTL), comprising carbon particles between 95% and 100% by weight of the porous surface layer, wherein the porous surface layer is functionalized to control a degree of hydrophobicity or hydrophilicity and has a contact angle between 0° and 150°
A method of forming a porous transport layer on a porous transport layer (PTL), comprising:
- forming a coating ink comprising carbon particles;
- applying the coating ink to a surface of the PTL;
- applying heat or both heat and pressure to the porous transport layer coated with the coating ink to form a composite;
- heat treating the composite in an inert atmosphere or in vacuum to form the porous surface layer;
- and
- functionalizing the porous surface layer to control a degree of hydrophobicity or hydrophilicity, wherein and the porous surface layer has a contact angle between 0° and 150
