Abstract
Catalytic layers for use in the electrodes of fuel cells including a non-noble metal substrate layer coated with one or a few monolayers of noble metal, such as Pt. These thin, highly porous structures with large catalytically active surface areas, should exhibit a significantly higher power output per mg of Pt and per cm2 of the membrane than the current Polymer Electrolyte Fuel Cells catalytic layers.
Claims12
A nanostructured catalytic layer for use in fuel cells, the catalytic layer:
- comprising a porous nanostructured substrate made from a first material and a surface layer wherein the surface layer is a catalytic material and is a different material than said first material, and wherein the nanostructured catalytic layer is carbon-free and has a thickness of from 0.1 to 10 μm.
A catalytic layer according to 3, wherein a platinum loading in said catalyst layer is from 0.04 to 0.1 mg/cm2.
