Abstract
Title: Method for providing a substrate for an electrochemical cell with a catalytic material Abstract The invention relates to a method for providing a substrate for an electrochemical cell with a catalytic material. The method comprises atomic layer deposition (ALD) that comprises providing a catalyst precursor for the catalytic material. The ALD further comprises providing a carrier precursor for forming a carrier material. The invention further relates to a substrate provided with a catalytic material and a PEM electrolysis cell comprising a substrate provided with a catalytic material.
Claims16
A method for providing a substrate for an electrochemical cell with a catalytic material wherein said method comprises atomic layer deposition (ALD) comprising depositing nanoparticles on a substrate, wherein the nanoparticles comprise core-shell nanoparticles that comprise a core comprising a carrier material and a shell comprising the catalytic material, and wherein said ALD comprises:
- providing a gaseous carrier precursor and allowing said carrier precursor to react with the substrate, followed by
- providing a second gaseous counter reactant and allowing said second gaseous counter reactant to react with the carrier precursor forming the carrier material, followed by
- providing a gaseous catalyst precursor for the catalytic material and selectively reacting the catalyst precursor with the carrier material, followed by
- providing a first gaseous counter reactant and allowing said first gaseous counter reactant to react with said catalyst precursor forming said catalytic material.
