PURPOSE:To improve gas penetration, electric conductivity, and mechanical strength by bonding warps and wefts with carbide at their crossing part by the use of carbon fiber fabrics. CONSTITUTION:Carbon fiber fabrics 12 are used for flat-shaped porous electrode plates. The warps and wefts of the fabrics 12 are bonded with carbide at their crossing part. These electrode plates are made, for example, as follows; carbon fiber fabrics 12 are laminated and a methanol solution of phenol resin is impregnated there, then a laminated material is put between two metallic flat plates to be heated under pressure for some tens of minutes at the temperature of 100-200 deg.C, thus the warps and wefts of the fabrics 12 are bonded with phenol resin at their crossing part, to obtain an electrode element, and succeedingly, the electrode element is fired under the inactive atmosphere of nitrogen gas and the like for some tens of minutes at the temperature of more than 1,000 deg.C, in order to obtain the electrode plates 1 and 2 with phenol resin being carbonized. |
