Abstract
Proposed are a porous transport layer (PTL), a composition for forming the same, and a method of forming the same. The porous transport layer contains 30 to 80 wt % of a metallic fiber-type material and 20 to 70 wt % of a metallic particle-type material, with respect to the total weight of the layer. In this case, each metal of the metallic fiber-type material and the metallic particle-type material includes a metal selected from the group consisting of titanium, zirconium, hafnium, nickel, stainless steel, and combinations thereof.
Claims19
A porous transport layer (PTL) comprising:
- 30 to 80 wt % of a metallic fiber-type material;
- and
- 20 to 70 wt % of a metallic particle-type material, with respect to a total weight of the layer,
- wherein each metal of the metallic fiber-type material and the metallic particle-type material comprises a metal selected from the group consisting of titanium, zirconium, hafnium, nickel, stainless steel, and combinations thereof.
A composition for forming a porous transport layer (PTL), the composition comprising:
- a metallic fiber-type raw material;
- a metallic particle-type raw material;
- and
- a solvent,
- wherein the metallic fiber-type raw material and the metallic particle-type raw material have contents of 30 to 80 wt % and 20 to 70 wt %, with respect to a total weight of the metallic fiber-type raw material and the metallic particle-type raw material, respectively, and
- wherein each metal of the metallic fiber-type raw material and the metallic particle-type raw material comprises a metal selected from the group consisting of titanium, zirconium, hafnium, nickel, stainless steel, and combinations thereof.
