Fig. 12. Effect of temperatures of cell stack and condenser on discharge characteristic. 3.4 EFFECT OF TEMPERATURE OF CONDENSER ON DISCHARGE CHARACTERISTICS When the temperature of gaseous hydrogen leaving the condenser (the temperature of the condenser) is shifted from a standard temperature of 70.5 °C to a temperature of 69°C or 72°C, the terminal voltage as a function of discharge time is illustrated in Fig. 10. It is concluded that if a temperature of coolant into the cell stack is maintained at 80°C, the terminal voltage is affected very little by changing the temperature of gaseous hydrogen leaving the condenser. In addition, the asbestos matrices do not dry up and the electrolyte solution does not leak out behind the electrodes. 3.5 EFFECT OF TEMPERATURE OF CELL STACK AND CONDENSER ON DISCHARGE CHARACTERISTICS It is foreseen that the temperature rise of the cell stack and the temperature drop of the condenser will have a bad influence on the discharge characteristics, because water in the asbestos matrices tends to evaporate easier and the asbestos matrices dry up. The effect of the temperatures of the cell stack and the condenser on the
