Problems solved by technology

At present, hydrogen storage technologies can be mainly divided into three types: high-pressure gas, liquid hydrogen and hydrogen storage alloys. Among them, high-pressure gas hydrogen storage has higher energy, weight and density, but is larger in size and less safe.

Embodiment Construction

[0058] The specific embodiments adopted by the present invention will be further described through the following embodiments and accompanying drawings.

[0059] see figure 1 and figure 2 It shows a system architecture diagram of the present invention and a circuit block diagram of an information identification label. As shown in the figure, there is a fuel cell stack 1 in a fuel cell system 100 of an application device, which generates a current output to a load (not shown) through the electrochemical reaction of hydrogen and air, and the fuel cell stack 1 reacts The heat is dissipated through a heat exchanger 11.

[0060] The cathode gas (in this embodiment, air) required for the reaction of the fuel cell stack 1 is supplied by an air supply source 2, and then sent into the fuel cell stack 1 after humidity adjustment by a humidifier 21; and the fuel cell stack 1 The anode gas (hydrogen in this embodiment) required for the reaction is supplied by a hydrogen storage tank 3,...

Abstract

The invention relates to a method for detecting a hydrogen residue of a hydrogen storage tank by applying label information. The method comprises the following steps of: configuring an information recognition label on the hydrogen storage tank, wherein at least one piece of label information which represents the hydrogen storage is stored in the information recognition label; reading the label information of the information recognition label; detecting consumption of the hydrogen which is supplied by the hydrogen storage tank; subtracting the hydrogen consumption from the hydrogen storage to solve the hydrogen residue; updating the label information of the information recognition label according to the solved hydrogen residue or storing the hydrogen residue.

Description

technical field [0001] The invention relates to a method for detecting the amount of hydrogen in a hydrogen storage tank, in particular to a method for detecting the remaining amount of hydrogen in a hydrogen storage tank by using label information. Background technique [0002] Whether it is a hydrogen fuel cell system or other products using hydrogen fuel cells, hydrogen supply is required. At present, hydrogen storage technologies can be mainly divided into three types: high-pressure gas, liquid hydrogen and hydrogen storage alloys. Among them, high-pressure gas hydrogen storage has higher energy, weight and density, but is larger in size and less safe. Although the energy, weight and density of the liquid hydrogen storage method are relatively high, the liquefaction energy consumption is large, and an insulated storage tank must be used at the same time, which is more suitable for large storage tanks. In the general application field, the hydrogen storage alloy should b...
