Abstract
A method enables preparation of a stock or starting material having improved catalytic properties. These materials will be useful in the formation of articles adapted for use in electrochemical fuel cells.
Claims16
A material useful as a substrate for preparing an article of an embossed or unembossed flexible graphite sheet, the material comprising:
- a compressed sheet of graphite comprised of intercalated graphite particles having fuel cell catalyst included therein, said catalyst comprises a platinum group metal.
A process for preparing a material useful as a substrate for preparing an article of an embossed or unembossed flexible graphite sheet, comprising:
- intercalating a sheet of flexible graphite to an extent necessary to form graphite intercalation compounds which increase the thermal and/or electrical conductivity of the graphite sheet, wherein an intercalant for said intercalating comprises a platinum group metal;
- and compressing the sheet following intercalation.
