Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] Such as figure 1 A hydrogen fuel cell system with high safety is shown, which is installed in the trunk 1 of the vehicle and is mainly used in trams, buses and new energy vehicles. The system includes a hydrogen fuel cell 2 for power supply, A hydrogen gas cylinder 3 for supplying hydrogen to the hydrogen fuel cell 2 and a hydrogen gas pipeline 4 arranged between the hydrogen fuel cell 2 and the hydrogen gas cylinder 3, a hydrogen solenoid valve 5 is arranged on the hydrogen gas pipeline 4, and a hydrogen gas solenoid valve 5 is arranged on the hydrogen gas pipeline 4. Above the hydrogen pipeline 4, a storage box 6 is arranged, especially at the interface of the hydrogen pipeline 4, hydrogen leakage is prone to occur. Since the hydrogen leaks and then moves upward, the bottom of the storage box 6 is open, and the storage box 6 is set The spongy palladium allo...

Abstract

The invention relates to a high-safety hydrogen fuel cell system, which is arranged in a vehicle trunk and comprises a hydrogen fuel cell, a hydrogen cylinder for supplying hydrogen and a hydrogen pipeline arranged between the hydrogen fuel cell and the hydrogen cylinder. The hydrogen pipeline is provided with a hydrogen electromagnetic valve; a containing box is arranged above the hydrogen pipeline; an opening is formed in the lower side of the containing box; a spongy palladium alloy is arranged in the containing box; the spongy palladium alloy is used for absorbing leaked hydrogen; a control processor is arranged beside the hydrogen fuel cell; and the control processor is connected with a hydrogen electromagnetic valve. Through the system, since the palladium alloy has the hydrogen absorption function, hydrogen can be absorbed in a centralized mode in time to be prevented from escaping after leaking, the content of hydrogen is reduced, the risk of explosive combustion is reduced, and the overall safety is improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cell use safety, in particular to a hydrogen fuel cell system with high safety. Background technique [0002] As oil is decreasing and environmental pollution is becoming more and more serious, it is an inevitable development trend to replace oil with new energy sources. The environmental protection advantages of hydrogen fuel cells, which are close to zero pollution, have gradually been discovered by governments of various countries and encouraged to use them. Hydrogen fuel cells are hydrogen A power generation device that directly converts the chemical energy of oxygen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the anode and cathode respectively. After the hydrogen diffuses outward through the anode and reacts with the electrolyte, electrons are released to reach the cathode through an external l...
