In the related art, during the activation process of the fuel cell, the inlet pressures of the cathode plate and the anode plate are kept at fixed values, and as the current density rises, the gas flow continuously rises, which causes a pressure drop between the inlet and the outlet of the gas. Especially, when the gas flow directions of the cathode plate and the anode plate of the fuel cell are opposite, a large pressure difference is formed between the two sides of the membrane electrode assembly at the anode inlet and the cathode outlet, and the mechanical performance of the membrane electrode assembly is damaged due to the generation of the pressure difference. When the differential pressure exceeds the bearing capacity of the membrane electrode assembly, the aging of the membrane electrode assembly is accelerated, even the rupture of the membrane electrode assembly can cause the damage of a cell stack, and the overlarge differential pressure on the two sides of the membrane electrode assembly can cause the hydraulic diameter of a cathode side distribution area of a fuel cell to be reduced, thereby generating a water flooding phenomenon.

Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
First, as shown in fig. 2, in the prior art, during the activation of the fuel cell, the pressure of the cathode inlet 40 and the anode inlet 20 is kept constant, and as the current density increases, the gas flow rate continuously increases, which causes a pressure drop between the anode inlet 20 and the anode outlet 30, and a pressure drop between the cathode inlet 40 and the cathode outlet 50.
Resulting in a large pressure difference between the anode inlet 20 and the cathode outlet 50, which may cause the mea 10 to move toward the cathode side (see the dotted line portion of fig. 2), causing damage to the mechanical properties of the mea, and when the pressure difference exceeds the endurance capacity of the mea 10, aging of the mea 10 may be accelerated, or even rupture of the mea 10 may be caused, thereby causing damage to the stack.
Meanwhile, the pressure drop generation between the anode inlet 20 and the anode outlet 30 and the pressure drop generation between the cathode inlet 40 and the cathode outlet 50 are all related to the gas flow rate, the pressure and the hydraulic diameter (a path for discharging the working product of the fuel cell), and under the same pressure, the larger the flow rate is, the larger the pressure drop is, and under the same flow rate, the larger the pressure drop is, and the larger the hydraulic diameter is, the smaller the pressure drop is.
Therefore, in the activation process of the existing fuel cell (stack), when the current density is low, the flow rate is reduced due to the excessively high voltage, so that a flooding phenomenon (that is, the working product of the fuel cell cannot be discharged in time and is accumulated on the cathode side) occurs inside the fuel cell, and further, when the current density is high, the cathode pressure drop is increased, so that the pressure difference between the two sides of the end part of the membrane electrode assembly 10 is further increased, the hydraulic diameter is reduced, and the flooding phenomenon is further worsened.
An activation method of a fuel cell according to an embodiment of the invention is described below with reference to fig. 1 to 2.
As shown in fig. 1, according to the activation method of the fuel cell according to the embodiment of the first aspect of the present application, the anode plate and the cathode plate of the fuel cell are spaced apart by the membrane electrode assembly, the anode inlet 20 and the cathode outlet 50 are located at the first end of the membrane electrode assembly, and the anode outlet 30 and the cathode inlet 40 are located at the second end of the membrane electrode assembly.
Wherein the activation method comprises the following steps: acquiring a first end pressure difference; if the first end pressure differential exceeds the threshold, the cathode inlet 40 pressure is raised to reduce the first end pressure differential.
It is understood that the threshold represents a threshold for pressure differential, and that different fuel cell sizes and sizes may be set appropriately by those skilled in the art in practicing the method of the present application,
specifically, in the activation method of the fuel cell of the present application, first, a pressure difference of a first section where the anode inlet 20 and the cathode outlet 50 are located is obtained, and when the pressure difference exceeds a first threshold, it is determined that the membrane electrode assembly 10 will move toward the cathode side under the action of the pressure difference, and the pressure of the cathode inlet 40 is raised, as described above, as the pressure of the cathode inlet 40 is raised, the pressure drop between the cathode inlet 40 and the cathode outlet 50 is reduced, so that the pressure of the cathode outlet 50 is higher by raising the pressure of the cathode inlet 40, and it is ensured that the pressure difference between the anode inlet 20 and the cathode outlet 50 is within the threshold, so as to effectively reduce the displacement amount of the membrane electrode assembly 10 toward the cathode side.
According to the activation method of the fuel cell, the pressure difference of the first end is obtained in real time, when the pressure difference exceeds the threshold value, the pressure of the cathode inlet 40 is raised, so that the movement amplitude of the membrane electrode assembly 10 towards the cathode side is reduced, a large pressure difference can be prevented from being directly applied to the membrane electrode assembly 10, the membrane electrode assembly 10 is prevented from being damaged in mechanical performance, the aging speed of the membrane electrode assembly 10 is reduced, the service lives of the membrane electrode assembly 10 and the fuel cell are prolonged, the hydraulic diameter of the cathode side is prevented from being extruded by the membrane electrode assembly 10, the hydraulic diameter of the cathode side is prevented from being changed, the drainage characteristic of the cathode side is kept stable, the drainage effect of the cathode side is improved, the water logging phenomenon of the cathode side is avoided, and the working stability of the activated fuel cell is improved.
It should be noted that, if the fuel cell is flooded, the fuel cell may need to be shut down urgently, so that the membrane electrode assembly 10 has an open circuit point, and the life of the membrane electrode assembly 10 is reduced.
According to some embodiments of the present application, raising the cathode inlet 40 pressure while raising the anode inlet 20 pressure ensures that the anode inlet 20 pressure is greater than the cathode inlet 40 pressure.
It should be noted that when the cathode inlet 40 pressure is raised, it may cause the cathode inlet 40 pressure to be higher than the anode inlet 20 pressure, which may cause the gas on the cathode side to diffuse to the anode side, resulting in a hydrogen-air interface on the anode side, causing the opposite pole or membrane electrode assembly to degrade.
Further, the anode inlet 20 is raised while the pressure of the cathode inlet 40 is raised, and it is ensured that the pressure of the anode inlet 20 is greater than the pressure of the cathode inlet 40 to prevent the gas diffusion phenomenon from occurring at the anode side, thereby improving the operation stability of the fuel cell.
According to some embodiments of the application, the activation method further comprises: the current density of the fuel cell is obtained, and an initial anode inlet pressure and an initial cathode inlet pressure are set according to the current density.
Specifically, if the fuel cell is in a high electrical density condition, the initial anode inlet pressure and the initial cathode inlet pressure are set to high pressures; if the fuel cell is in a low electrical density condition, the initial anode inlet pressure and the initial cathode inlet pressure are set to low pressures. This makes the pressures at the anode inlet 20, the anode outlet 30, the cathode inlet 40, and the cathode outlet 50 more reasonable, and improves the activation efficiency and the activation level.
It is understood that acquiring the first end pressure differential includes: obtaining an initial anode inlet pressure, and obtaining an anode outlet 30 pressure; obtaining an initial cathode inlet pressure, and obtaining a cathode outlet 50 pressure; initial anode inlet pressure-cathode outlet 50 pressure-the first end pressure differential.
Where the cathode outlet 50 pressure is the initial cathode inlet pressure-cathode drop and the anode outlet 30 pressure is the initial anode inlet pressure-anode drop. Thus, the activation method of the application can obtain the pressure of the cathode outlet 50, the pressure of the anode inlet 20 and the pressure difference between the cathode outlet 50 and the anode inlet 20 more accurately in the activation process of the fuel cell, and can improve the accuracy of pressure regulation of the cathode inlet 40 and the anode inlet 20, thereby improving the activation stability.
According to some embodiments of the application, further comprising: the first end pressure differential continues to be acquired. That is, after adjusting the cathode inlet 40 and anode inlet 20 pressures, the first end pressure differential continues to be acquired, and when the first end pressure differential again exceeds the threshold, the cathode inlet 40 pressure and anode inlet 20 pressure are further adjusted.
In some embodiments, the minimum activation voltage during activation of the fuel cell is 0.2 v. Thereby, the activation efficiency can be accelerated to improve the activation efficiency of the fuel cell.
Further, the cathode inlet 40 pressure is less than the anode outlet 30 pressure.
Next, the activation method of the fuel cell of the present application will be explained with a specific example.
When the pressure at the anode inlet 20 is set to 210kPaa and the anode plate has the highest flow rate at the electric density of 2.0A/cm2, the pressure drop of the anode is 10kPa, and the pressure at the anode outlet 30 is 200 kPaa;
setting the pressure at the cathode inlet 40 to 200kPa, the pressure drop at the cathode plate to 100kPaa, and the pressure at the cathode outlet 50 to 100kPaa, where the pressure difference at the anode inlet 20 of the MEA is 210-100 kPa, which is much higher than the working pressure of the general MEA.
Further, the cathode inlet 40 pressure is raised, the pressure drop is reduced with the pressure rise, the cathode inlet 40 pressure is raised to 250kPaa, the cathode pressure drop is reduced from 100kPa to 50kPa, the cathode outlet 50 pressure is 200kPaa, the anode inlet 20 pressure is raised to 260kPa, and the anode outlet 30 pressure is not lower than 250 kPaa.
At this time, the pressure at the anode inlet 20 to the cathode outlet 50 is 60kPaa smaller than the initial 110kPaa, and the displacement width of the membrane electrode assembly 10 toward the cathode side can be reduced, thereby reducing the pressure difference between both sides of the membrane electrode assembly 10 and improving the drainage characteristics.
Based on the above, in the activation process of the fuel cell, the pressure setting is related to the current density, the low electricity density maintains the low voltage, the flooding caused by insufficient flow rate is improved, the high electricity density sets the high voltage, and the inlet pressures of the cathode plate and the anode plate are raised according to the pressure drop, so that the hydraulic diameter deformation is reduced, the deformation of the membrane electrode assembly 10 is reduced, the flooding problem caused by overlarge pressure drop is improved, and the activation process is smoothly carried out.
