Detailed Description
Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
First, as shown in fig. 2, in the prior art, during the activation of the fuel cell, the pressures of the cathode inlet 40 and the anode inlet 20 remain constant, and as the current density increases, the gas flow rate increases continuously, 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 can cause the membrane electrode assembly 10 to move toward the cathode side (see the dotted line portion of fig. 2), cause damage to the mechanical properties of the membrane electrode assembly, and when the pressure difference exceeds the withstand capability of the membrane electrode assembly 10, accelerate the aging of the membrane electrode assembly 10, even cause the rupture of the membrane electrode assembly 10, and further cause damage to the galvanic pile.
Meanwhile, the pressure drop between the anode inlet 20 and the anode outlet 30 and the pressure drop between the cathode inlet 40 and the cathode outlet 50 are related to the gas flow rate, the pressure and the hydraulic diameter (the path for discharging the working product of the fuel cell), at the same pressure, the larger the flow rate, the larger the pressure drop, the smaller the pressure drop, the larger the hydraulic diameter and the smaller the pressure drop.
Based on this, in the (stack) activation process of the existing fuel cell, when the current density is low, the flow rate is reduced due to the excessively high voltage, so that the flooding phenomenon (i.e., the working product of the fuel cell cannot be discharged in time and accumulated on the cathode side) occurs in the fuel cell, and when the current density is high, the cathode pressure drop becomes large, so that the pressure difference on both sides of the end portion of the membrane electrode assembly 10 is further increased, the hydraulic diameter is reduced, and the flooding phenomenon is further deteriorated.
A method of activating a fuel cell according to an embodiment of the present 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.
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 the threshold of the pressure difference, and the thresholds of the fuel cells with different specifications and sizes are different, so that those skilled in the art can reasonably set during the practical application of the method of the present application,
specifically, in the activation method of the fuel cell of the present application, first, the pressure difference between the anode inlet 20 and the cathode outlet 50 is obtained, and when the pressure difference exceeds the first threshold value, it is determined that the membrane electrode assembly 10 will move towards the cathode side under the action of the pressure difference, and the pressure of the cathode inlet 40 is raised, as described above, the pressure drop between the cathode inlet 40 and the cathode outlet 50 is reduced as the pressure of the cathode inlet 40 rises, so that the pressure of the cathode outlet 50 is higher by raising the pressure of the cathode inlet 40, and the pressure difference between the anode inlet 20 and the cathode outlet 50 is ensured to be within the threshold value, so as to effectively reduce the displacement amount of the membrane electrode assembly 10 towards the cathode side.
According to the activation method of the fuel cell in the embodiment of the invention, the first end pressure difference is obtained in real time, and when the pressure difference exceeds the threshold value, the pressure of the cathode inlet 40 is raised to reduce the movement amplitude of the membrane electrode assembly 10 towards the cathode side, so that the larger pressure difference can be prevented from directly acting on the membrane electrode assembly 10, the mechanical property damage of the membrane electrode assembly 10 is avoided, the aging speed of the membrane electrode assembly 10 is slowed down, the service life of the membrane electrode assembly 10 and the fuel cell is prolonged, the hydraulic diameter of the cathode side is prevented from being extruded by the membrane electrode assembly 10, the change of the hydraulic diameter of the cathode side is avoided, the drainage characteristic of the cathode side is kept stable, the drainage effect of the cathode side is improved, the flooding 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, emergency shutdown of the fuel cell may be required, resulting in an open circuit point of the membrane electrode assembly 10, and further, a life of the membrane electrode assembly 10 may be reduced.
According to some embodiments of the present application, the cathode inlet 40 pressure is raised while the anode inlet 20 pressure is raised and the anode inlet 20 pressure is ensured to be greater than the cathode inlet 40 pressure.
It should be noted that when the pressure of the cathode inlet 40 is raised, the pressure of the cathode inlet 40 may be higher than the pressure of the anode inlet 20, 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 deterioration of the counter electrode or the membrane electrode assembly.
Further, the anode inlet 20 is raised while the cathode inlet 40 pressure is raised, and it is ensured that the anode inlet 20 pressure is greater than the cathode inlet 40 pressure, so that the gas diffusion phenomenon at the anode side is avoided, thereby improving the operation stability of the fuel cell.
According to some embodiments of the present 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-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 a low pressure. Thus, the pressures at the anode inlet 20, the anode outlet 30, the cathode inlet 40, and the cathode outlet 50 are all more reasonable, and the activation efficiency and activation level can be improved.
It will be appreciated that obtaining the first end pressure differential includes: acquiring an initial anode inlet pressure and an anode outlet 30 pressure; acquiring an initial cathode inlet pressure and a cathode outlet 50 pressure; initial anode inlet pressure-cathode outlet 50 pressure = first end pressure differential.
Wherein cathode outlet 50 pressure = initial cathode inlet pressure-cathode drop, anode outlet 30 pressure = initial anode inlet pressure-anode drop. Thus, in the activation method of the present application, the pressure of the cathode outlet 50, the pressure of the anode inlet 20 and the pressure difference between the two are obtained more accurately in the activation process of the fuel cell, so that the accuracy of pressure regulation of the cathode inlet 40 and the anode inlet 20 can be improved, and the activation stability can be improved.
According to some embodiments of the application, further comprising: the first end pressure differential continues to be obtained. That is, after the cathode inlet 40 and anode inlet 20 pressures are adjusted, the first end pressure difference is continuously obtained, and when the first end pressure difference exceeds the threshold again, the cathode inlet 40 pressure and anode inlet 20 pressure are further adjusted.
In some embodiments, the minimum activation voltage during fuel cell activation is 0.2v. 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, an explanation will be given of an activation method of the fuel cell of the present application in one specific example.
When the anode inlet 20 pressure was set to 210kPa, the anode pressure drop was 10kPa at the anode plate at the highest flow rate at an electrical density of 2.0A/cm2, and the anode outlet 30 pressure was 200 kPa;
when the cathode inlet 40 pressure is set to 200kapa and the cathode plate pressure drop is set to 100kPaa, the cathode outlet 50 pressure is set to 100kPaa, and the MEA anode inlet 20 pressure difference is 210-100=110 kPa, which is much larger than the operating pressure of a typical MEA.
Further, as the pressure increases, the pressure drop decreases by raising the cathode inlet 40 pressure to 250kPaa, the cathode pressure drop decreases from 100kPa to 50kPa, the cathode outlet 50 pressure is 200kPaa, and the anode inlet 20 pressure is raised to 260kPa, the anode outlet 30 pressure is not lower than 250kPaa.
At this time, the anode inlet 20 pressure-cathode outlet 50 pressure=60 kPaa is smaller than the initial 110kPaa, so that the displacement width of the membrane electrode assembly 10 toward the cathode side can be reduced, the pressure difference across the membrane electrode assembly 10 can be reduced, and the drainage characteristics can be improved.
Based on the above, in the activation method of the application, in the activation process of the fuel cell, the pressure setting is related to the current density, the low electric density is kept at low pressure, flooding caused by insufficient flow rate is improved, the high electric density is set at high pressure, 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.
