摘要： PURPOSE:To improve gas sealing structure at the edge of electrode to increase reliability by mounting thermoplastic films from a right angle direction to the grooves and the same direction as the grooves at the edge of an electrode with rib. CONSTITUTION:A thermoplastic film 7 is mounted from the same direction as grooves at the edge of electrode with rib 2, then a thermoplastic film 6 is mounted from a right angle direction to the grooves so as to cover the film 7. By heating, each film is melted and pressed to bond them and a gas sealing part is formed. Fluorine resin film such as PTFE, PFA, or FEP having heat resistance and phosphoric acid resistance and a thickness of 0.01-3mm is used as the thermoplastic films 6 and 7.

摘要： PURPOSE:To increase sealing capability by arranging a sealing member comprising a kneaded mixture of graphite and fluorine oil, and a fluorine resin tape between the end of a rib-installed electrode placed on one side of a matrix and a gas separating plate. CONSTITUTION:A pair of rib-installed electodes 2 in which gas passages are formed are palced on both sides of a matrix 1 into which electrolyte is impregnated to form a unit cell. A plurality of unit cells are stacked through a gas separating plate 3 to form a fuel cell. A sealing member comprising a kneaded mixture 5 of 30-60 wt% graphite powder and 70-40 wt% fluorine oil, and a fluorine resin tape 6 is placed between the end of the rib-installed electrode 2 and the gas separating plate 3 before the fuel cell is assembled. Thereby, elasticity and adhesion between the end of the electrode and the gas separating plate are increased. Therefore, gas leakage from the end space is surely prevented and the life of the fuel cell is lengthened.

摘要： PURPOSE:To increase gas sealing ability at the edge of a rib-installed matrix by sealing the edge parallel to passage grooves of a rib-installed matrix with thermoplastic resin film, and embedding particles having anchor effect on the contact surface of the film with the matrix. CONSTITUTION:An edge 7 parallel to passage grooves 2 of a rib-installed electrode 3 is covered with a thermoplastic film 9 in which particles having anchor effect are embedded onto the surface to be made to contact a matrix. A material which is easy to wet to phosphoric acid, and uniformly scattered on the film 9 when the thermoplastic film 9 is heat-pressed into the electrode 3 such as silicon carbide, or graphite is used as particles 8 having anchor effect. By embedding particles 3, the surface of the film is improved, and by anchor effect of particles 3, coagulation of the matrix 1 is prevented. Therefore, gas ability at the edge of rib-installed electrode is increased.

摘要： PURPOSE:To make thin, compact, and lightweight by embedding cooling pipes each of which has an oval cross section in a cooling plate. CONSTITUTION:A plurality of cooling pipes 10' each of which has an oval cross section are embedded in a conductive constituent 9 at regular intervals. The conductive constituent 9 has high electric conductivity and heat conductivity, phosphoric acid resistance and heat resistance. A graphite resin plate obtained by molding a mixture of thermosetting resin and graphite particles or an impermeable graphite plate obtained by impregnating resin in the graphite resin plate as impermeable treatment is used as the conductive constituent. As the cooling pipe 10', a copper pipe is generally used in terms of heat conductivity and processability. By making the pipe having the same diameter as the regular one oval, its surface area remains as it is, cooling effect remains unchanged and the cooling plate can be made thin and lightweight.
