Abstract
An improved platinum and method for manufacturing the improved platinum wherein the platinum having a fractal surface coating of platinum, platinum gray, with a increase in surface area of at least 5 times when compared to shiny platinum of the same geometry and also having improved resistance to physical stress when compared to platinum black having the same surface area. The process of electroplating the surface coating of platinum gray comprising plating at a moderate rate, for example at a rate that is faster than the rate necessary to produce shiny platinum and that is less than the rate necessary to produce platinum black. Platinum gray is applied to manufacture a fuel cell and a catalyst.
Claims11
An anode and/or a cathode comprising a substrate wherein the surface coating is electroplated to the surface of said conductive substrate at a rate such that the metal particles form on the conductive substrate faster than necessary to form shiny platinum and slower than necessary to form platinum black.
A method for manufacturing of a catalyst by electroplating a surface coating such that surface has a rough surface coating comprising:
- electroplating the surface of a conductive substrate at a rate such that the particles are form on the conductive substrate faster than necessary to form shiny platinum and slower than necessary to form platinum black.
