<p>PURPOSE:To make an electrode plate of excellent electric and thermal properties, by jointing two portions of an electrode unit to opposite sides of a separator in such a manner that they are orthogonal to reaction gas hole passages and in confrontation each other and jointing an edge seal member to an extended portion of the separator adjacent to a circumferential portion of the electrode unit. CONSTITUTION:A porous carbon electrode unit 2 has two portions jointed to opposite sides of a separator 1, respectively in such a manner that they are orthogonal to a reaction gas hole passages 8 and in confrontation each other. An edge seal member 3 is jointed to both sides of an extended portion of the separator 1 adjacent to a circumferential portion of the electrode unit 2. Further, gas dispersing units 4 are jointed to the extended portion of the separator 1 parallel to the reaction gas hole passages 8 to form an electrode plate for a fuel cell. At the time, jointing surfaces of the electrode unit 2 and the separator 1 are jointed through a flexible carbon sheet 6 and jointing surfaces of the separator 1 and the seal member 3 and those of the separator 1 and the gas dispersing unit 4 are jointed through a fluorocarbon resin 5. In addition, a reaction gas passage 7 is provided with the gas dispersing units 4 in the circumferential portion perpendicular to the reaction gas hole passages 8.</p> |
