摘要：1,223,941. Fuel cells. VARTA A.G. 10 March, 1969 [15 March, 1968], No. 12504/69. Heading HlB. Inert gas is vented from the last cell of a fuel battery, in which gas flows serially through at least some of the electrodes of one polarity, by a valve controlled by the output of the last electrode, the valve being opened for a predetermined period of time when the output of the last electrode drops to a determined value, and after the valve has closed again its operation is blocked for an adjustable dead time so that reactant gas is not lost during the delay in the recovery of the output of the last electrode. A fuel battery is described in which a. solenoid valve is operated by a relay in the output stage of a two-stage transistor-direct current amplifier with a capacitor parallel to the coil of the relay controlling the time of opening and a capacitor in the basevoltage divider of a third transistor preceding the second stage controlling the dead time.
