Cathode for hydrogen generation
View Patent ↗The present invention provides a cathode for hydrogen generation comprising a cathode substrate having provided thereon a catalytic layer, wherein the catalytic layer contains at least three components of platinum, cerium and lanthanum in amounts of 50 to 98 mol %, 1 to 49 mol % and 1 to 49 mol %, respectively, in the form of metal, metal oxide or metal hydroxide.
1. A cathode for hydrogen generation comprising a cathode substrate having provided thereon a catalytic layer, wherein the catalytic layer contains at least three components of platinum, cerium and lanthanum in amounts of 50 to 98 mol %, 1 to 49 mol % and 1 to 49 mol %, respectively, in the form of metal, metal oxide or metal hydroxide.
2. The cathode for hydrogen generation according to claim 1 , wherein the catalytic layer further comprises a platinum-group metal other than platinum in an amount of 1 to 49 mol % in the form of metal, metal oxide or metal hydroxide.
3. The cathode according to claim 1 or 2 , which further comprises an intermediate layer containing a conductive oxide between the cathode substrate and the catalytic layer.
4. The cathode according to claim 3 , wherein the intermediate layer comprises an oxide containing at least one of nickel and titanium.
