Fuel cell rechargeable gas supply manifold system

Abstract

The invention discloses a filling-type gas supply confluence system of a fuel cell. The system consists of a gas filling unit, a gas bottle confluence switching unit and a safety unit which are successively connected with one another. The gas filling unit is a double-circuit pipeline parallel structure, and each circuit is serially connected with an outer interface, a ball valve and a stop valve. The gas bottle confluence switching unit is also a double-circuit pipeline parallel structure, each circuit is serially connected with two to five hydrogen valves, each hydrogen valve is connected with a hydrogen bottle by virtue of a corrugated pipe, and the last hydrogen valves in the two circuits are respectively connected with two ends of a distribution valve and uniformly output high-pressure hydrogen. The safety unit is provided with a low-pressure hydrogen output passage formed by a filter, a decompressor and an electromagnetic valve, and for a safety reason, the passage is provided with a discharging passage consisting of a safety valve, a bypass valve and a flame arrester. Two circuits of pipelines are used for alternately supplying the gas, the idle pipeline is convenient for replacing the hydrogen bottle or on-site filling the hydrogen, and since the hydrogen is supplemented in time, the fuel cell can supply power continuously.

Description

technical field [0001] The invention relates to a valve-controlled charging system, in particular, the invention relates to a hydrogen confluence system for charging a fuel cell. Background technique [0002] Today, fuel cells with advanced technology and large specific capacity have become one of the backup power sources for mobile communication base stations. Fuel cells used online can be supplemented by external injection of hydrogen. Existing hydrogenation technologies mainly include replacement of hydrogen cylinders, configuration of integrated methanol reforming hydrogen generators or electrolytic water hydrogen generators. Combining the advantages and disadvantages of the above three hydrogenation technologies, it can be seen that the method of replacing hydrogen cylinders is one of the easiest and most economical methods in the existing technology, but the operation safety is slightly worse, and accidents may easily occur if there is a slight carelessness. The fuel ...
