Title: Fuel cell system
Inventor: UEKUSA HIDEO
IPC: H01M8/06
Filed: 1986-04-11
Abstract: PURPOSE:To retard methanation reaction in a high temperature sifting chamber by supplying hydrogen sulfide to a carbon monoxide hygh temperature sifting chamber when the temperature of the carbon monoxide high temperature sifting chamber into which reformed gas is introduced from a reformer reched allowable temperature. CONSTITUTION:Original fuel is introduced into a catalyst layer comprising nickel in a reformer 1. Carbon monoxide is removed from the reformer gas obtained in a carbon monoxide high temperature sifting chamber 2 and a carbon monoxide low temperature sifting chamber 3 by carbon monoxide sifting reaction, then obtained gas is supplied to a fuel electrode of a fuel cell 4. A hydrogen sulfide tank 5 is connected between the reformer 1 and the carbon monoxide high temperature sifting chamber 2 through a supply valve 6. When the temperature in the carbon monoxide high temperature sifting chamber 2 is incresed with the advance of deterioration in performance of the reformer 1 and reached allowable temperature, hydrogen sulfide is supplied to the sifting chamber 2 to retard methanation reaction. Therefore, deterioration in catalytic action in the sifting chamber 2 is prevented and the life is lengthened.

Abstract: PURPOSE:To prevent the slipping between an outside and an inside tape, and to reduce transfer variation, by making the outside tape, wound around the rotating roller of a transfer device, wider than the inside tape, and running part of the outside tape in contact with the rotating roller. CONSTITUTION:A rotating roller 4 having a rubber layer 13 on the surface is wound with a slave tape 2 and a master tape 6 on the surface of the tape 2, and a transfer magnetic field is applied by a transfer head 10 from above them to transfer information on the master tape 6 to the slave tape 2. The master tape 6 is made wider than the slave tape 2 to bring the edges of the master tape 6 into direct contact with the rubber layer 13 on the surface of the roller 4, reducing the slipping between both the tapes finished into specular surfaces. Consequently, widthwise and lengthwise shifts between both the tapes are reduced, so variation in transfer output and variation in transfer pattern are also reduced.
