The fuel cell stack is a core of a fuel cell power generation system, and is formed by stacking and combining a plurality of unit cells in series. The bipolar plates and the membrane electrodes are alternately overlapped, sealing elements are embedded between the monomers, and the sealing elements are tightly pressed by the front end plate and the rear end plate and then fastened by screw bolts, thus forming the fuel cell stack.
The fuel cell has the advantages of high power generation efficiency and small environmental pollution, but the current fuel cell stack has a common problem that when the current fuel cell stack is found to have faults, the general damage degree is large, so that the fuel cell stack basically cannot be used continuously or the maintenance cost is too high.
Through researches, the failure cause is mainly that under the vibration inside the fuel cell, the external vibration and the slight collision impact, the problems of dislocation, deformation, abrasion and the like can occur between the sealant line and the polar plate, so that the stress inside the electric pile is uneven. The current fuel cell stack lacks the function of effectively judging the stress distribution of the stack in the initial and running processes of the stack, especially the stress condition in the stack, and the internal fatigue and the sealing state of the rubber line cannot be effectively detected before failure, so that the fault of the fuel cell stack can be discovered only when the damage degree of the fuel cell stack is great, and at the moment, the fuel cell stack cannot be continuously used or the maintenance cost is too high basically.
In order to solve the above problems, the present utility model provides a stack system and a power device for monitoring the pressure distribution of a fuel cell stack.

In this embodiment, the pressure detecting device is configured to detect a pressure in the electric pile, convert a pressure signal into an electrical signal, and transmit the electrical signal to the control device.
And the control device is used for outputting an alarm prompt signal to the upper computer when the pressure value corresponding to the pressure signal is larger than a preset pressure value, receiving a control signal fed back by the upper computer and performing shutdown control on the electric pile.
In this embodiment, when the problems such as dislocation, deformation, and wear occur in the pile, the pressure detecting device disposed in the pile detects the pressure change, and the pressure detecting device transmits the detected signal to the control device, and the control device analyzes the electrical signal transmitted by the pressure detecting device. In order to avoid misjudgment, a pressure reference value, namely the preset pressure value, can be set to represent the damage degree of dislocation, deformation and abrasion in the pile. For example, 3% exceeding the normal pressure inside the stack may be set as the preset pressure value.
When the control device recognizes that the pressure value is larger than the preset pressure value, the control device judges that the pressure problem exists in the electric pile, and outputs an alarm prompt signal to the upper computer so as to enable the upper computer to make fault diagnosis or processing correspondingly.
Therefore, the utility model can effectively judge the distribution of the stress of the electric pile in the initial and running processes of the electric pile, especially the stress condition in the initial and running processes of the electric pile, can effectively monitor the internal fatigue before failure, and can timely process the fatigue, thereby reducing the maintenance cost.
