PURPOSE:To improve air permeability, conductivity and mechanical strength of electrode plates in the caption through the formation of the electrode plates equipped with ribs by using carbon fiber fabrics for the board part with its entanglement part bonded with a carbide and using short carbon fibers for the rib part with its intersecting points bonded with a carbide. CONSTITUTION:One unit of a fuel cell is formed by installing electrode plates 1, 2 equipped with ribs, which support catalyst through the interposition of electrolyte. The electrode plates 1, 2 are constituted by forming its board part 9 by means of one to several carbon fiber fabrics 10 with its part of warp and weft entanglement bonded with a carbide produced through calcination of phenol fibers, forming the rib part 7 by means of short carbon fibers 11 with its intersecting points bonded with a carbide and uniting both with the same carbide. Through the use of carbon fiber fabrics, it is possible to secure high air permeability, good conductivity and firm form-maintaining capability and thereby improve performance and durability of the electrode plates greatly. |
