Description

Technical Field

[0001] The invention relates to the technical field of energy utilization, and in particular to a PEM hydrogen production coupling system. Background Art

[0002] Under the background of the "two carbon goals", the energy structure has become a trend towards green, low-carbon and clean development. Hydrogen has become a widely-watched new energy source due to its good combustion performance and its combustion products are pollution-free to the environment. For example, hydrogen is widely used in the field of new energy vehicles. In new energy vehicles, hydrogen is used as fuel for hydrogen fuel cells to generate electricity through chemical reactions.

[0003] The water electrolysis hydrogen production process refers to the process in which water is dissociated into oxygen and hydrogen under electrolysis, which are precipitated from the anode and cathode of the electrolyzer respectively. At present, the more mature water electrolysis hydrogen production processes include alkaline water hydrogen production technology and PEM (Chinese name: proton exchange membrane) hydrogen production technology. The investment and operating costs of alkaline water hydrogen production technology are low, but there are problems such as alkali loss, corrosion, and high energy consumption. PEM hydrogen production technology is a hot spot in hydrogen production research and is developing rapidly. Compared with traditional hydrogen production technology, PEM hydrogen production uses water for electrolysis to produce hydrogen, which is clean and safe and can operate stably for a long time; the proton exchange membrane used in the PEM system can effectively isolate the hydrogen and oxygen produced on both sides of the anode and cathode, has better safety, and the hydrogen produced is of high purity.

BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Figure 1 It is a schematic diagram of the system principle. DETAILED DESCRIPTION

[0043] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] Example 1

[0045] Firstly, the data on hydrogen production, power, duration and days required for the PEM hydrogen production coupling system are collected through the hydrogen production collection module, power collection module, duration collection module and day collection module of the data collection unit, and the 60-minute standard power consumption required for the 60-minute standard hydrogen production required by the PEM hydrogen production coupling system is acquired through the hydrogen production acquisition module and power acquisition module of the parameter acquisition unit.

[0046] Then, the data receiving module of the core processing unit receives the data about the PEM hydrogen production unit collected by the data acquisition unit and the parameters about the PEM hydrogen production unit acquired by the parameter acquisition unit, and the analysis and processing module analyzes and processes the data and parameters about the PEM hydrogen production unit received by the data receiving module, and the report generating module generates a report on the PEM hydrogen production coupling system according to the analysis and processing results of the analysis and processing module.

[0047] The analysis and processing module can obtain the hydrogen production of the PEM hydrogen production unit, the power consumed in the hydrogen production process, the standard hydrogen production in 60 minutes and the standard power consumption in 60 minutes during the analysis and processing, and obtain the efficiency index of the PEM hydrogen production unit through comprehensive analysis of the above data:

[0048]

[0049] Therefore, the efficiency index of the PEM hydrogen production unit is used to judge the quality of the hydrogen production effect of the PEM hydrogen production unit. The larger the efficiency index of the PEM hydrogen production unit, the better the hydrogen production effect of the PEM hydrogen production unit. Conversely, the worse the hydrogen production effect of the PEM hydrogen production unit. Among them, XI is the efficiency index of the PEM hydrogen production unit, V i is the hydrogen production of the PEM hydrogen production unit, Q ij is the power consumed in the hydrogen production process, V is the standard hydrogen production in 60 minutes, Q is the standard power consumption in 60 minutes, n1 is the hydrogen production time, and n2 is the type of electricity source used in the hydrogen production process.

[0050] At the same time, the analysis and processing module can obtain the stability index of the PEM hydrogen production unit through comprehensive analysis based on the total hydrogen production time, the duration of each failure, the interval between two adjacent failures, the total number of hydrogen production days, and the number of days with failures:

[0051]

[0052] Therefore, the stability of the PEM hydrogen production unit in the hydrogen production process can be understood according to the stability index of the PEM hydrogen production unit. The larger the stability index of the PEM hydrogen production unit, the better the stability of the PEM hydrogen production unit in the hydrogen production process. Conversely, the worse the stability of the PEM hydrogen production unit in the hydrogen production process. Among them, SZ is the stability index of the PEM hydrogen production unit, T is the total hydrogen production time, GT is i is the duration of each failure, JT i The interval between two consecutive failures, ZD is the total number of days for hydrogen production, GD is the number of days with failures, and n3 is the number of failures.

[0053] The threshold value of the relevant results of the report generated by the analysis and processing of the core processing unit is set by setting the threshold setting module of the feedback unit, and the corresponding report generated by the analysis and processing of the core processing unit is obtained by the report acquisition module. The result comparison module compares the result of the report obtained by the report acquisition module with the threshold set by the threshold setting module, and sends the corresponding instruction to the display reminder unit through the instruction sending module according to the comparison result of the result comparison module.

[0054] When the result comparison module is performing result comparison, when the efficiency index of the PEM hydrogen production unit is less than the threshold value of the efficiency index of the PEM hydrogen production unit set by the threshold setting module, or when the stability index of the PEM hydrogen production unit is less than the threshold value of the stability index of the PEM hydrogen production unit set by the threshold setting module, the instruction issuing module sends instructions to the display reminder unit, and the warning reminder module issues corresponding warning reminders to the operator, so as to detect problems in time and deal with them.

[0055] The report and instruction receiving module of the display reminder unit receives the report generated by the core processing unit analysis and processing and the relevant instructions issued by the setting feedback unit, and displays the report generated by the core processing unit analysis and processing received by the report and instruction receiving module through the report display module. At the same time, when the report and instruction receiving module receives the instructions issued by the setting feedback unit, a warning reminder is issued through the warning reminder module.

[0056] Example 2

[0057] When the analysis and processing module obtains the efficiency index of the PEM hydrogen production unit by analyzing the hydrogen production amount of the PEM hydrogen production unit, the power consumed in the hydrogen production process, the 60-minute standard hydrogen production amount and the 60-minute standard power consumption, V=265,Q=925,n1=120,the efficiency index of the PEM hydrogen production unit can be calculated:

[0058]

[0059] At this time, the result comparison module compares 0.496 with the preset threshold value of the efficiency index of the PEM hydrogen production unit. If 0.496 is less than the preset threshold value of the efficiency index of the PEM hydrogen production unit, the instruction issuing module sends an instruction to the display reminder unit for a warning. Otherwise, no warning is given.

[0060] Example 3

[0061] The analysis and processing module can obtain the stability index of the PEM hydrogen production unit by comprehensive analysis based on the total hydrogen production time, the duration of each failure, the interval between two adjacent failures, the total number of hydrogen production days and the number of days with failures. When T=11520 is obtained, ZD=8,GD=2, then the stability index of the PEM hydrogen production unit can be calculated:

[0062]

[0063] At this time, the result comparison module compares 1.415 with the preset threshold value of the stability index of the PEM hydrogen production unit. If 1.415 is less than the preset threshold value of the stability index of the PEM hydrogen production unit, the command issuing module sends an instruction to the display reminder unit for a warning. Otherwise, no warning is given.

[0064] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
