Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the schematic diagram of the present invention:

[0015] Such as figure 1 As shown, a fuel cell hydrogen gas supply system (1) for self-sufficient charging provided by the present invention includes a hydrogen generator (2), a bus bar (3), and a fuel cell system (12). Roads are connected sequentially. The hydrogen generator (2) passes through the booster pump (4), the pressure gauge (5) and is connected to the busbar (3) in sequence; the busbar (3) passes through the flame arrester (6), the safety valve (11), and the control valve in sequence (10) and connected to the fuel cell system (12).

[0016] The busbar (3) is composed of two hydrogen pipelines. As shown in the figure, the upper and lower hydrogen pipelines are respectively connected to three hydrogen cylinders (7a)-(7c) and (7d)-(7f). The upper hydrogen pipeline has a one-way inlet valve (8a) at the beginning and an outlet valve (9a) ...

Abstract

The invention discloses a self-filling fuel cell hydrogen supply system. The system comprises a hydrogen generating unit and a hydrogen storage and supply unit, wherein the hydrogen generating unit is used for generating hydrogen which enters the hydrogen storage and supply unit through a booster pump; the hydrogen storage and supply unit is used for storing the hydrogen and supplying the hydrogen for a fuel cell system; water finally produced during a reaction in the fuel cell system is also provided for the hydrogen generating unit to be used for producing hydrogen continuously. According to the invention, a great deal of manpower and material resources can be saved, and the system is low in operation cost, free of maintenance and low in energy consumption, thus having wide application prospects.

Description

technical field [0001] The invention relates to a fuel cell hydrogen gas supply system for self-sufficiency charging, and specifically relates to the field of fuel cells. Background technique [0002] At present, the hydrogen used in the fuel cell system is mainly provided by high-pressure hydrogen cylinders. Since the amount of hydrogen stored in a single cylinder is relatively small, it is necessary to manually replace the hydrogen cylinder when the hydrogen is used up. In order to supply the fuel cell system to work for a long time, the current solution can generally use multiple groups of gas cylinders to connect in series, thereby increasing the working time of the fuel cell system; or use the patent "Double Independent Fuel Cell Hydrogen Supply In the method of "Gas System", multiple gas supply systems are used, and when the hydrogen cylinder of one of the gas supply systems is replaced, another group of gas supply systems provides hydrogen for the fuel cell system. T...
