摘要:
A method and a system meters a supply of methanol and/or water out of a storage reservoir to a fuel-cell system by way of a conveying conduit with a metering valve. A constant mass flow is conveyed out of the storage reservoir into the conveying conduit via a conveying pump. The differential pressure between the conveying conduit and fuel-cell system is set at a predetermined value via a differential-pressure controller which is arranged in a return conduit provided between the conveying conduit and storage reservoir. The methanol and/or water supplied can be set, for example, by varying the opening and closing times of a solenoid valve. A second metering stage can be provided in the return conduit downstream of the first metering stage. When two separate metering systems are used, a common pump motor can be employed.
