Background

A fuel cell is a chemical device that directly converts chemical energy of fuel into electrical energy, and is also called an electrochemical generator. The fuel cell has high energy conversion efficiency and no pollution, is becoming an ideal energy utilization mode, and has wide development prospect.

In the related art, the pem fuel cell is one of the fuel cells, and since the electrolyte membrane used in the pem fuel cell is solid, the electrolyte corrosion can be avoided, and the pem fuel cell has the characteristics of high energy efficiency and energy density, small volume and weight, short cold start time, safe and reliable operation and the like, the pem fuel cell has a wide application range and is gradually applied to fixed power stations. In the process of using the proton exchange membrane fuel cell, a fuel cell group with certain power needs to be formed by the series connection and the parallel connection of the single cells, so that the demand of most of electric loads can be met. In addition, it is necessary to arrange a fuel feeding unit, an oxidizer feeding unit, a temperature adjusting unit, a humidity adjusting unit, a power converting unit, a system control unit, and the like so that the fuel cell stack becomes a continuous and stable power supply. Because the proton exchange membrane fuel cell needs to perform fuel feeding, oxidant feeding, temperature regulation and humidity regulation in the using process, the system control unit controls the fuel feeding unit, the oxidant feeding unit, the temperature regulation unit and the humidity regulation unit when the proton exchange membrane fuel cell is used, so that the fuel feeding unit, the oxidant feeding unit, the temperature regulation unit and the humidity regulation unit are matched with each other to operate.

In view of the above-mentioned related art, the inventors found that the following drawbacks exist: in practical use, one or more of the fuel feeding, the oxidant feeding, and the temperature and humidity are easily changed due to the influence of external factors, for example, the fuel feeding or the oxidant feeding is easily insufficient due to the external factors, and the temperature and humidity are easily changed due to the influence of the environment, when the system control unit cannot timely control the fuel feeding unit, the oxidant feeding unit, the temperature adjusting unit, and the humidity adjusting unit, the fuel feeding unit, the oxidant feeding unit, the temperature adjusting unit, and the humidity adjusting unit are not in a mutually cooperating state, so that the fuel feeding amount, the oxidant feeding amount, the temperature value, and the humidity value are not in a proper range, thereby easily damaging internal parts of the proton exchange membrane fuel cell, and further reducing the service life of the proton exchange membrane fuel cell.

The hydrogen fuel feeding early warning value is obtained by inquiring a database in which the hydrogen fuel feeding early warning value is stored, and the hydrogen fuel feeding early warning value refers to the maximum feeding amount of the hydrogen fuel during feeding.

And judging whether the required hydrogen fuel feeding amount is larger than the maximum feeding amount of the hydrogen fuel when the hydrogen fuel is fed or not by judging whether the required hydrogen fuel feeding amount is larger than a preset hydrogen fuel feeding early warning value or not.

In step S367, a difference between the hydrogen fuel feeding warning value and the current hydrogen fuel feeding amount is analyzed and calculated as reactant adjustment information according to the hydrogen fuel feeding warning value and the current hydrogen fuel feeding amount.

When the required hydrogen fuel feeding amount is larger than the preset hydrogen fuel feeding early warning value, the required hydrogen fuel feeding amount is larger than the maximum feeding amount when the hydrogen fuel is fed, so that the difference between the hydrogen fuel feeding early warning value and the current hydrogen fuel feeding amount is calculated, and the difference between the hydrogen fuel feeding early warning value and the current hydrogen fuel feeding amount is used as reactant adjustment information, so that the accuracy of the reactant adjustment information is improved, and the safety of the fuel cell during use is improved.

In step S368, a difference between the required hydrogen fuel feed amount and the current hydrogen fuel feed amount is analyzed and calculated as reactant adjustment information, based on the required hydrogen fuel feed amount and the current hydrogen fuel feed amount.

When the required hydrogen fuel feeding amount is not more than the preset hydrogen fuel feeding early warning value, the required hydrogen fuel feeding amount is not more than the maximum feeding amount when the hydrogen fuel is fed, so that the difference between the required hydrogen fuel feeding amount and the current hydrogen fuel feeding amount is calculated, and the difference between the required hydrogen fuel feeding amount and the current hydrogen fuel feeding amount is used as reactant adjustment information, so that the accuracy of the reactant adjustment information is improved, and the safety of the fuel cell during use is improved.

In step S400 shown in fig. 1, in order to further ensure the rationality of the adjustment output information, it is necessary to further separately analyze and calculate the adjustment output information, and the detailed description will be given by the steps shown in fig. 5.

Referring to fig. 5, analyzing and acquiring the adjustment output information corresponding to the current state information and the adjustment input information according to the corresponding relationship between the current state information, the adjustment input information, and the adjustment output information includes the following steps:

in step S410, current status information and adjustment input information are obtained.

Step S420, determining whether the adjustment input information is only one of the hydrogen fuel input feed amount, the oxygen input feed amount, the temperature input value, and the humidity input value. If yes, go to step S430; if not, go to step S450.

Whether the adjustment input information is only one of the hydrogen fuel input feed amount, the oxygen input feed amount, the temperature input value and the humidity input value is judged, so that whether the adjustment input information comprises a plurality of adjustment input information is judged, and the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value and the adjusted humidity value are conveniently analyzed and obtained subsequently.

And step S430, analyzing and acquiring a corresponding one of the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value and the adjusted humidity value according to the adjustment input information and the corresponding one of the current hydrogen fuel feed amount, the current oxygen feed amount, the current temperature value and the current humidity value.

When the adjustment input information is only one of the hydrogen fuel input feed amount, the oxygen input feed amount, the temperature input value and the humidity input value, analyzing and acquiring the corresponding one of the hydrogen fuel input amount after adjustment, the oxygen input feed amount after adjustment, the temperature value after adjustment and the humidity value after adjustment by using the adjustment input information and the corresponding one of the current hydrogen fuel input amount, the current oxygen input amount, the current temperature value and the current humidity value.

For example, when the adjustment input information is only the hydrogen fuel input feed amount, the adjusted hydrogen fuel feed amount is analyzed and obtained through the hydrogen fuel input feed amount and the current hydrogen fuel feed amount.

Step S440, analyzing and obtaining a corresponding one of the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value, and using the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value as adjustment output information.

When one of the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value is obtained through analysis, the remaining three of the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value corresponding to the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value are obtained through analysis through one of the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted humidity value.

For example, after the adjusted hydrogen fuel feeding amount is analyzed and obtained, the adjusted oxygen feeding amount is analyzed and obtained through the adjusted hydrogen fuel feeding amount due to the fact that consumption between the hydrogen fuel and the oxygen is fixed in the same time. Because the adjusted oxygen feeding amount and the adjusted hydrogen fuel feeding amount have influence on the temperature and the humidity, if the adjusted oxygen feeding amount and the adjusted hydrogen fuel feeding amount are higher than the original oxygen feeding amount and the original hydrogen fuel feeding amount, the temperature is increased and the humidity is reduced. And analyzing and acquiring the adjusted temperature value and the adjusted humidity value at the moment according to the adjusted oxygen feeding amount and the adjusted hydrogen fuel feeding amount.

Step S450, analyzing and acquiring the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value according to the judgment result of whether the adjustment input information simultaneously comprises the hydrogen fuel input feeding amount and the oxygen input feeding amount, and taking the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value as adjustment output information.

When the adjustment input information is only a plurality of hydrogen fuel input feed amount, oxygen input feed amount, temperature input value and humidity input value, the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value and the adjusted humidity value are analyzed and obtained through judging results of whether the adjustment input information simultaneously comprises the hydrogen fuel input feed amount and the oxygen input feed amount, so that the accuracy of analyzing and obtaining the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value and the adjusted humidity value is improved.

In step S450 shown in fig. 5, in order to further ensure the reasonableness of analyzing and acquiring the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value, and the adjusted humidity value, it is necessary to further perform separate analysis and calculation on the analyzed and acquired adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value, and the adjusted humidity value, and the steps shown in fig. 6 will be specifically described in detail.

Referring to fig. 6, according to the determination result of whether the adjustment input information includes the hydrogen fuel input feed amount and the oxygen input feed amount at the same time, analyzing and obtaining the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value, and the adjusted humidity value includes the following steps:

in step S451, it is determined whether the adjustment input information includes both the hydrogen fuel input feed amount and the oxygen input feed amount. If not, go to step S452; if so, step S454 is executed.

Whether the hydrogen fuel input feed amount and the oxygen input feed amount are included in the adjustment input information or not is judged, so that the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value and the adjusted humidity value can be conveniently analyzed and obtained subsequently.

Step S452, analyzing and acquiring a plurality of the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value, and the adjusted humidity value according to the corresponding relationship between the adjustment input information and a plurality of the current hydrogen fuel feed amount, the current oxygen feed amount, the current temperature value, and the current humidity value.

When the adjustment input information does not simultaneously include the hydrogen fuel input feed amount and the oxygen input feed amount, analyzing and acquiring a plurality of the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value and the adjusted humidity value through the corresponding relationship between the adjustment input information and a plurality of the current hydrogen fuel feed amount, the current oxygen feed amount, the current temperature value and the current humidity value.

For example, when the adjustment input information includes the hydrogen fuel input feed amount and the temperature input value, the hydrogen fuel input feed amount after adjustment is analyzed and obtained according to the hydrogen fuel input feed amount and the current hydrogen fuel feed amount, and the temperature value after adjustment is analyzed and obtained according to the temperature input value and the current temperature value.

Step S453 is to analyze and obtain the remaining ones of the plurality of adjusted hydrogen fuel feed amounts, the adjusted oxygen feed amounts, the adjusted temperature values, and the adjusted humidity values corresponding to the adjusted hydrogen fuel feed amounts, the adjusted oxygen feed amounts, the adjusted temperature values, and the adjusted humidity values according to the corresponding relationships among the adjusted hydrogen fuel feed amounts, the adjusted oxygen feed amounts, the adjusted temperature values, and the adjusted humidity values.

When a plurality of the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value are obtained through analysis, the rest of the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value corresponding to the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value are obtained through analysis through a plurality of the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value.

For example, after the adjusted hydrogen fuel feeding amount and the adjusted temperature value are obtained by analysis, the adjusted oxygen feeding amount is obtained by analyzing the adjusted hydrogen fuel feeding amount because the consumption between the hydrogen fuel and the oxygen is constant in the same time. Because the adjusted temperature value has an influence on the humidity, if the adjusted temperature value is increased relative to the original temperature value, the humidity is decreased. And analyzing and obtaining the adjusted humidity value at the moment according to the adjusted temperature value.

Step S454, analyzing and acquiring the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value, and the adjusted humidity value according to the determination result of whether the hydrogen fuel input feed amount is equal to twice the oxygen input feed amount.

When the adjustment input information simultaneously comprises the hydrogen fuel input feed amount and the oxygen input feed amount, the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value and the adjusted humidity value are analyzed and obtained according to the judgment result of whether the hydrogen fuel input feed amount is equal to twice of the oxygen input feed amount, so that the accuracy of the obtained adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value and the adjusted humidity value is improved.

In step S454 shown in fig. 6, in order to further ensure the reasonableness of analyzing and acquiring the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value, and the adjusted humidity value, it is necessary to further perform individual analysis and calculation on the analyzed and acquired adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value, and the adjusted humidity value, and the steps shown in fig. 7 will be specifically described in detail.

Referring to fig. 7, analyzing and obtaining the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, the adjusted temperature value, and the adjusted humidity value according to the determination result of whether the hydrogen fuel input feed amount is equal to twice the oxygen input feed amount includes the following steps:

Wherein, whether the hydrogen fuel feed amount and the oxygen feed amount input by the operator can be consumed at the same time is judged by judging whether the hydrogen fuel input feed amount is equal to twice the oxygen input feed amount.

And step S4542, alarm information is output.

When the hydrogen fuel input feed amount is not equal to twice of the oxygen input feed amount, the hydrogen fuel input feed amount and the oxygen input feed amount input by an operator cannot be consumed at the same time, so that alarm information is output at the moment, and a prompt is generated for the operator.

Step S4543 is performed to determine whether the adjustment input information further includes one or more of a temperature input value and a humidity input value. If yes, go to step S4544; if not, go to step S4546.

When the hydrogen fuel input feed amount is equal to twice the oxygen input feed amount, the hydrogen fuel feed amount and the oxygen feed amount input by the operator can be consumed at the same time. At this time, whether the adjustment input information further comprises one or more of the temperature input value and the humidity input value is judged, so that whether conditions which need to influence the adjustment strategy subsequently exist in the adjustment input information input by an operator at this time is judged.

Step S4544, analyzing and acquiring one or more of the adjusted temperature value and the adjusted humidity value according to the corresponding relationship between the adjustment input information and one or more of the current temperature value and the current humidity value.

When the adjustment input information further includes one or more of the temperature input value and the humidity input value, it indicates that a condition that needs to be subsequently influenced on the adjustment strategy exists in the adjustment input information input by the operator at this time. And analyzing and acquiring one or more of the adjusted temperature value and the adjusted humidity value by adjusting one or more corresponding input information and the current temperature value and the current humidity value.

For example, when the adjustment input information further includes a temperature input value, the adjusted temperature value is analyzed and obtained through the temperature input value and the current temperature value.

And step S4545, analyzing and acquiring the remaining hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value corresponding to one or more of the adjusted temperature value and the adjusted humidity value according to the corresponding relation among the adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value.

The remaining ones are analyzed and obtained by analyzing one or more of the obtained adjusted temperature value and the obtained adjusted humidity value, so that the adjusted hydrogen fuel feeding amount and the adjusted oxygen feeding amount are not easily changed by the temperature value and the humidity value and need to be adjusted for many times. Therefore, the accuracy of the obtained adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount, the adjusted temperature value and the adjusted humidity value is improved.

For example, when the adjustment input information further includes a temperature input value, the adjusted hydrogen fuel feed amount, the adjusted oxygen feed amount, and the adjusted temperature value are directly analyzed and obtained by analyzing the obtained adjusted temperature value. Therefore, the obtained adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount and the adjusted temperature value can be matched with each other, so that the accuracy of the obtained adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount and the adjusted temperature value is improved, and the service life of the fuel cell is prolonged.

And directly analyzing and acquiring the adjusted hydrogen fuel feeding amount and the adjusted oxygen feeding amount through adjusting the input information, the current hydrogen fuel feeding amount and the current oxygen feeding amount.

And analyzing the adjusted temperature value and the adjusted humidity value through analyzing the obtained adjusted hydrogen fuel feeding amount and the adjusted oxygen feeding amount. Therefore, the accuracy of the obtained adjusted hydrogen fuel feeding amount, the adjusted oxygen feeding amount and the adjusted temperature value is improved.
