Title:
MANUFACTURING ENHANCED GRAPHITE METALLIC BIPOLAR PLATE MATERIALS
Document Type and Number:
WIPO Patent Application WO/2019/060503
Kind Code:
A3
Abstract:
The present invention includes methods of manufacturing a metal infused graphitic material. Also described is how this device may be rendered impermeable. The present invention includes the electroplating/electroless deposition of metal on exposed internal and external surfaces of a porous graphitic substrate. The deposition of metal on the internal structure is accomplished by replacing the void space in the porous substrate with an electrolyte solution containing dissolved metallic species. The plating is initiated either through electrochemical means, electroless means, chemical vapor deposition means, or other means obvious to one familiar in the art of metal plating. A post-deposition bath is also described wherein the plating may be removed from one or both sides of the external surface without impacting the internal pore plating.
