Abstract
A graphite article in the form of a flexible graphite sheet having transverse fluid channels passing through the sheet and a groove formed in one of the surfaces of the sheet communicating with a plurality of the transverse fluid channels is presented, wherein the open groove comprises a groove floor and groove walls, the groove walls having transverse fluid channels passing therethrough.
Claims19
A graphite article comprising a compressed mass of expanded graphite particles in the form of a sheet having opposed first and second surfaces, the sheet having a plurality of transverse fluid channels passing therethrough between its first and second opposed surfaces, one of the opposed surfaces having formed therein an open groove which communicates with a plurality of the transverse fluid channels,
- wherein the open groove comprises a groove floor and groove walls, the groove walls having transverse fluid channels passing therethrough.
A substrate suitable for formation of a component for an electrochemical fuel cell comprising (i) a compressed mass of expanded graphite particles in the form of a sheet having opposed first and second surfaces, the sheet having a plurality of transverse fluid channels passing therethrough;
- one of the opposed surfaces having formed therein an open groove which communicates with a plurality of the transverse fluid channels and (ii) a sheet of flexible graphite bonded to the surface in which the groove is formed to provide a cover therefore,
- wherein the open groove comprises a groove floor and groove walls, the groove walls having transverse fluid channels passing therethrough.
A method for forming a graphite article comprising providing a compressed mass of expanded graphite particles in the form of a sheet having opposed first and second surfaces, forming in the sheet a plurality of transverse fluid channels passing therethrough between its first and second opposed surfaces, forming on one of the opposed surfaces of the sheet an open groove which communicates with a plurality of the transverse fluid channels,
- wherein the open groove comprises a groove floor and groove walls, the groove walls having transverse fluid channels passing therethrough.
