Pulse hydrogen supply system for proton exchange membrane fuel cell

A pulse hydrogen supply system for a proton exchange membrane fuel cell, comprising:

• a fuel cell, a high-pressure hydrogen bottle, a first pressure relief valve, an ejector, a steam-water separator, a first pressure control valve, and a first pressure sensor,
• wherein the ejector is arranged on a gas inlet pipeline communicated between the high-pressure hydrogen bottle and an anode inlet of the fuel cell,
• the first pressure relief valve is arranged on the gas inlet pipeline adjacent to the high-pressure hydrogen bottle, the steam-water separator is arranged on a first output pipeline at the anode outlet of the fuel cell,
• the first pressure control valve is arranged on the gas inlet pipeline at a front end of the ejector, and
• the first pressure sensor is arranged on the gas inlet pipeline adjacent to the anode inlet of the fuel cell,
• the pulse hydrogen supply system further comprises:
• a high-pressure vessel, a first electromagnetic valve, a low-pressure vessel, a diaphragm pump, and a second electromagnetic valve,
• wherein a pressure in the high-pressure vessel is higher than an operation pressure of the fuel cell and a pressure in the low-pressure vessel is less than the operation pressure of the fuel cell,
• wherein the high-pressure vessel is arranged on a branch pipeline of the gas inlet pipeline between the first pressure relief valve and the first pressure control valve, and
• the first electromagnetic valve is also arranged on the branch pipeline,
• the second electromagnetic valve, the low-pressure vessel and the diaphragm pump are sequentially arranged on the first output pipeline between the anode outlet of the fuel cell and the steam-water separator, and
• the first output pipeline and the gas inlet pipeline form a loop.
