The tapes are wound of a first pair of spaced apart reels (31,31') at identical linear velocity and their inside surfaces are brought into a close relationship while the tapes are moved through the gap between two graphite block collectors (12.12') which are urged onto the tape outsides. After having passed the collectors the tapes are separated again and wound up on a second pair of spaced apart reels (32,32'). Before entering the gap between the collectors an electrolyte (22), such as thionyl chloride in a paste condition is evenly applied to the inside surface of one of the tapes. As soon as the tape insides are in a close relationship to each other within the gap between the collectors, current starts to be generated by electro-chemical reaction and to be collected by the graphite collectors upon having reached the desired level and is then conducted to a consumer.Field of SearchDEFERRED ACTION TYPETape or flexible-type cell including tape fuel cells or subcombination thereof Responsive to movement of electrode on contained electrolyte HAVING MEANS FOR DRAINING OR REMOVING ELECTROLYTE FROM A CELL OTHER THAN FILLER OPENING HAVING MOVABLE MECHANICAL MEANS TO PROVIDE RELATIVE MOTION BETWEEN ELECTRODE AND ELECTROLYTE Means moves electrode Rotary motion Means moves electrolyte externally of electrode chamber PROCESS OF CELL OPERATION Including laminating of indefinite length material Including coating or impregnating |
