Intercalation compounds of bromine with graphite fibers, prepared by benzene decom-position, were used as electrodes in a con-centration cell. The following merits of applying the graphite fibers were clarified ; 1) high open-circuit voltage, 2) easy circulation of bromine gas, 3) low internal resistance, 4) long life. The open-circuit voltage depended strongly on the weight of electrode material of compounds as well as on the geometry of bridges for bromine gas and for KBr solution. By keeping the anode and cathode of inter-calation compounds (300mg) at 70°C and 15°C, respectively, the open-circuit voltage of 65 mV and short-circuit current of approximately 0.7 mA were obtained. The cell showed a high degree of performance over long periods of time, in comparison with the cell having compounds of graphite powder.
