Background
Fuel cells generate electrical energy by electrochemically reacting hydrogen gas at the anode and oxygen gas (air) at the cathode across a membrane. Before the fuel cell stack is delivered from a factory or before application, a fuel cell testing device is needed to check the performance of the fuel cell stack and to check whether the performance of the fuel cell stack can reach the set (or standard) technical index.
The fuel cell stack testing apparatus should be capable of starting operation of the fuel cell stack under various given conditions and providing safety protection to the fuel cell stack to avoid unnecessary damage to the fuel cell stack under severe conditions.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following describes specific technical solutions of the present invention in further detail with reference to the accompanying drawings in the embodiments of the present invention. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Fig. 1 is a schematic flow chart of an implementation of a safety control method according to an embodiment of the present invention, where the method is applied to a fuel cell testing apparatus, and as shown in fig. 1, the method includes:
step S101: a safety processing component obtains safety-related information of the fuel cell testing device from a process processing component.
It should be noted that the fuel cell testing device may be any device capable of providing a test for a fuel cell, and as an example, the fuel cell testing device may be a fuel cell stack testing device. For convenience of understanding, fig. 2 is a schematic diagram of a fuel cell testing apparatus according to an embodiment of the present invention, and as shown in fig. 2, only some components of the fuel cell testing apparatus are shown in fig. 2, and other components are not shown.
Here, the safety processing component obtains safety-related information of the fuel cell testing device from a process processing component, wherein the process processing component may include a process controller, which may be a process PLC as an example; the safety processing component may include a safety processor, which may be, as an example, a safety PLC; the safety-relevant information can be measured values of all safety-relevant process variables. Since the fuel cell testing device can transmit all measured values of the safety-relevant process variables to the process control component during the testing process, the safety control component can obtain safety-relevant information of the fuel cell testing device from the process control component.
Step S102: and judging whether the fuel cell testing device has a first safety fault according to the safety related information to obtain a first judgment result.
Here, the safety processing component may store in advance various safety related information corresponding to safety failure categories, where the safety related information corresponding to the safety failure categories may include safety related information corresponding to a first safety failure, safety related information corresponding to a second safety failure, safety related information corresponding to a third safety failure, and safety related information corresponding to a fourth safety failure, and the safety failure categories are classified according to the severity of a safety failure.
The abnormal safety-related information corresponding to the safety fault category may include abnormal safety-related information corresponding to a first safety fault with the highest severity, and since when the abnormal safety-related information corresponding to the first safety fault occurs, significant casualties and significant property loss may be caused, it is necessary to find the abnormal safety-related information corresponding to the first safety fault in time. As an example, the abnormal safety-related information corresponding to the first safety failure includes at least one of: the wind power of an exhaust system in the fuel cell testing device is less than a preset level; the hydrogen concentration in the fuel cell testing device exceeds the preset alarm concentration; an emergency shutdown command for the fuel cell testing device.
The determining, according to the safety-related information, whether the fuel cell testing device has a first safety fault may be performed, where the obtaining of the first determination result may be determining, according to the safety-related information, whether the fuel cell testing device has abnormal safety-related information corresponding to the first safety fault, and when the abnormal safety-related information corresponding to the first safety fault exists in the safety-related information, obtaining a first determination result, where the first determination result indicates that the fuel cell testing device has the first safety fault; and when the abnormal safety-related information corresponding to the first safety fault does not exist in the safety-related information, obtaining a first judgment result, wherein the first judgment result indicates that the first safety fault does not exist in the fuel cell testing device. As an example, the existence of the abnormal safety-related information corresponding to the first safety failure in the safety-related information may include at least one of: the wind power of an exhaust system in the fuel cell testing device is less than a preset level; the hydrogen concentration in the fuel cell testing device exceeds the preset alarm concentration; an emergency shutdown command for the fuel cell testing device.
In practical application, the wind power of the exhaust system in the fuel cell testing device is less than a preset level, and the wind power of the exhaust system in the fuel cell testing device can be detected to be less than 3 levels by the wind volume detector. Under normal conditions, the wind power of the exhaust system is generally greater than 3 grades, when the wind power of the exhaust system is detected by the wind volume detector to be less than 3 grades, the exhaust is unsmooth, the test bench possibly faces the risk that hydrogen is leaked and cannot be rapidly exhausted outdoors, and serious casualties and serious property loss are possibly caused due to extremely high hydrogen danger.
The hydrogen concentration in the fuel cell testing device exceeds the preset alarm concentration, and the combustible gas detector can detect that the hydrogen concentration in the fuel cell testing device exceeds the preset alarm concentration, so that the test board is in a serious unsafe state.
The emergency stop command of the fuel cell testing device may be an emergency stop command in which an operator activates an emergency stop switch arranged on a test stand or remotely triggers the fuel cell testing device.
Step S103: and under the condition that the first judgment result shows that the fuel cell testing device has a first safety fault, other power supplies except the power supply of the safety processing assembly are turned off, and first fault processing corresponding to the first safety fault is executed.
In practical application, when the fuel cell testing device has a first safety fault, an emergency shutdown command is generally started, the power supply of the whole testing platform is shut down, and the process processing component cannot work without the power supply, but in this step, when the first judgment result shows that the fuel cell testing device has the first safety fault, other power supplies except the power supply of the safety processing component are shut down, and the first fault processing corresponding to the first safety fault is executed, so that the safety processing component can also have the power supply after the emergency shutdown, and the safety processing component can still process the fault, so that the fault is eliminated.
Step S104: the first failure handling includes at least one of: and controlling a hydrogen supply electromagnetic valve and an air supply electromagnetic valve in the fuel cell testing device to be in an off state and controlling a nitrogen purging electromagnetic valve to be in an on state.
Here, controlling the hydrogen supply solenoid valve and the air supply solenoid valve in the fuel cell testing apparatus to be in an off state may be controlling the hydrogen supply solenoid valve and the air supply solenoid valve in the fuel cell testing apparatus to lose power, cutting off the hydrogen supply and the air supply; the nitrogen purging electromagnetic valve is controlled to be in a conducting state by controlling the nitrogen purging electromagnetic valve to be in a conducting state through controlling the nitrogen purging electromagnetic valve to be in a power-off normally-open state. In practical applications, the first fault processing may further include outputting a prompt message corresponding to the first safety fault, where the prompt message may prompt the type of safety fault by lighting indicator lamps with different colors, and as an example, when it is determined that the first safety fault is the first safety fault, the first safety fault may be prompted by lighting both red and yellow indicator lamps, and when the first fault is processed, the red and yellow indicator lamps are not lighted.
According to the safety control method provided by the embodiment of the invention, the safety processing assembly obtains the safety related information of the fuel cell testing device from the process processing assembly; judging whether the fuel cell testing device has a first safety fault according to the safety related information to obtain a first judgment result; under the condition that the first judgment result shows that the fuel cell testing device has a first safety fault, other power supplies except the power supply of the safety processing assembly are turned off, and first fault processing corresponding to the first safety fault is executed; the first failure handling includes at least one of: and controlling a hydrogen supply electromagnetic valve and an air supply electromagnetic valve in the fuel cell testing device to be in an off state and controlling a nitrogen purging electromagnetic valve to be in an on state. By adopting the technical scheme of the embodiment of the invention, under the condition that the first judgment result shows that the fuel cell testing device has the first safety fault, other power supplies except the power supply of the safety processing assembly are turned off, and the first fault processing corresponding to the first safety fault is executed, so that when the whole fuel cell testing device is turned off, the safety processing assembly also has the power supply, the fault can still be processed, and meanwhile, the fault processing speed is greatly improved.

In practical applications, the first fault processing may further include outputting a prompt message corresponding to the first safety fault, where the prompt message may prompt the type of safety fault by lighting indicator lamps with different colors, and as an example, when it is determined that the first safety fault is the first safety fault, the first safety fault may be prompted by lighting both red and yellow indicator lamps, and when the first fault is processed, the red and yellow indicator lamps are not lighted.
