PURPOSE:To enable performance to be maintained stably over the long period by injection-processing chlorine gas during a graphite-processing and using a rib-equipped electrode, which has less amount of staying impurity. CONSTITUTION:A rib-equipped electrode, which has functions of diffusion into a reactive field of a flow fuel and liquid oxidizing agent, are formed injection- processing chlorine gas during a graphite-processing of a rib-equipped electrode material. This rib-equipped electrode is formed, for example, as follows; a mixture of carbon fiber material with phenol resin is arranged having uniform thickness on the flat surface, and this material is hot-pressed and molded in an assigned thickness at the temperature 160-170 deg.C and then hardened- processed. Thereafter, a carbonized process of resin part is performed at the temperature of 1,100 deg.C, and an assigned flow-rate of chlorine gas is blown at an assigned time to obtain a carbon porous plate of the rib-equipped electrode 21, at the same time when the resin part is graphite-processed at the temperature of 1,500-2,500 deg.C, e.g., about 2,100 deg.C. Thus, an increase of contact resistance and drop of conductivity can be prevented without strength drop and buckling being generated even under operating conditions of high temperature and pressure, with performance being maintained stably over the long period. |
