PURPOSE:To obtain an electrode member whose assembly is easy, weight is light, conductivity is good, and electrolyte blocking capability is good by bonding a bipolar plate and an electrode body via a conductive adhesive. CONSTITUTION:A 0.1-1.0mm thick bipolar palte 3 comprising a composite material using carbon fiber as reinforcement and carbon black-containing thermosetting resin as a matrix is bonded to a carbon fiber electrode via conductive adhesive 4. The content of carbon black is limited to 0.5-10wt% based on the resin weight from the standpoint of condcutivity of the bipolar plate 3. The carbon black whose specific resistance under a pressure of 30kg/cm2 is 0.4omega/cm or less, volatile matter is 0.1% or less, ash is 0.5% or less is used. As the conductive adhesisve 4, carbon black-containing resin adhesive is used in terms of corrosion resistance to electrolyte, and its volume resistivity is 10 deg.OMEGA.cm or less. |
