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 obtain good workability at the time of mounting, excellent heat resistance and phosphoric acid resistance and besides good air-tightness by filling unvulcanized fluororubber composed of defoamed unvulcanized fluororubber and putty-like unvulcanized fluororubber in between a gasket and the contacting face with the gasket on the side face of a cell main body, vulcanizing with heating and sealing both of them tightly. CONSTITUTION:The configuration is that fluororubber 12 which is composed of defoamed unvulcanized fluororubber and putty-like unvulcanized fluororubber attached just as putty on the face side of this defoamed unvulcanized fluororubber contacting with electrodes 2, 3, is filled in between a gasket 9 and the gasket contacting face 10 of the side face of a fuel cell main body 7 to form a filler layer and both of them are sealed. Fluororubber before vulcanization has good workability because of no elasticity and clay-like property, and besides foaming occurs at the time of vulcanization with heating owing to flow by heating and a small amount of residual solvent in the putty-like unvulcanized fluororubber 12b part and rubber enters thoroughly in the uneven surface of the gasket contacting face 10. Thereby, perfect air-tightness can be obtained.

3 in the waste gas and to humidify the gas. Next, alkaline activated carbon suspension 6b of 10pH is sprayed in the 2nd scrubbing tower 9 to absorb off the greater part of the H
2 S in the gas. Since the pH of the suspension 6b decreases on absorption of H
2 S and CO
2 , a necessary amt. of the alkaline concd. liquid in a tank 12 is injected thereto by using a pH sensor 9, a pH controller 10 and a pump 11, whereby the pH is maintained constant. Next, in the 3rd scrubbing tower 14, an NaClO soln. is sprayed, and CH
3 SH and the like are absorbed and decomposed by oxidation. Finally, the alkaline activated carbon suspension of the 2nd scrubbing tower is conducted and sprayed in the 4th scrubbing tower 15 by means of a pump 16 to remove chlorine odors, after which the deodorized gas is discharged.
