PROCESS FOR PRODUCING A THIN CARBONACEOUS PLATE |
摘要 |
A thin carbonaceous plate useful, for example, as a separator in a fuel cell is prepared by a process wherein a carbonaceous raw material which is carbonized and solidifies after being softened by heating is press-molded by a heating press, the thus press-molded carbonaceous raw material is heated under pressure thereby to carbonize the said material and the thus carbonized material is calcined in a vacuum or in an inert gas to obtain the said thin carbonaceous plate, characterized in that a said carbonaceous raw material is sandwiched in the said heating press between layers of a paper-like substance capable of being carbonized without melting, the said layers of the said paper-like substance being in contact with the pressing surfaces of the heating press. |
