Description
Technical Field
The invention relates to the technical field of proton exchange membrane fuel cells, in particular to a method for monitoring the degree of reversal of the cell.
Background
A pem fuel cell is an electrochemical device that converts chemical energy of hydrogen into electrical energy and produces only water by using electrochemical reaction between hydrogen and air (or oxygen). In the actual use of the pem fuel cell, in order to obtain higher power output, the membrane electrodes are connected in series by means of bipolar plates to form a fuel cell stack. The coolant inside the bipolar plate is used to maintain the temperature at which the cell operates properly, and hydrogen and air (or oxygen) on both sides of the bipolar plate provide the reactants needed for the electrochemical reaction, respectively.
The membrane electrode is generally composed of a proton exchange membrane, an anode catalyst layer, a cathode catalyst layer, and gas diffusion layers located on both sides of the anode and cathode catalyst layers. The proton exchange membrane is selected from solid electrolytes capable of conducting protons and blocking electrons and gases, typically perfluorosulfonic acid resin materials; the anode catalyst layer is generally formed by bonding a Pt/C catalyst and a resin, and is a place where a Hydrogen Oxidation Reaction (HOR) occurs; the cathode catalyst layer is generally formed by bonding a Pt/C catalyst and a resin, and is a place where an Oxygen Reduction Reaction (ORR) occurs; the gas diffusion layer is mainly composed of two parts, a gas diffusion substrate (GDB) and a microporous layer (MPL), and functions mainly to support a catalytic layer, collect current, conduct gas, and discharge water, which is a reaction product.
During the actual operation of the electric pile, the voltage of one or more cells is negative, namely the potential of the anode (negative electrode) of the cells is higher than that of the cathode (positive electrode), so-called 'reverse polarity' is generated. Analysis shows that the insufficient hydrogen in the anode catalyst layer can cause the occurrence of the reverse pole, and factors such as insufficient external hydrogen supply, blockage of gas transmission channels by impurities, flooding and the like can cause the insufficient hydrogen in the anode catalyst layer, thereby inducing the occurrence of the reverse pole. In addition, the electric pile can also have reverse pole accidents under some dynamic working conditions (such as cold start, rapid load change and the like), because the transmission of hydrogen under the conditions has a delay effect, and the anode catalytic layer has a condition of insufficient hydrogen supply in a short time. After the reverse polarity occurs, the performance of the battery can be damaged irreversibly, and the performance and the durability of the battery are seriously influenced.
In the absence of hydrogen in the anode catalytic layer, the hydrogen oxidation reaction is limited, and it is difficult to release enough electrons and protons to maintain charge balance. In order to maintain charge balance throughout the system, other species of the anode catalytic layer (e.g., water and carbon support) undergo oxidation reactions, generating protons and releasing electrons, as follows:
H2O＝1/2O2+2H++2e-1.23V(vs.SHE)
C+2H2O＝CO2+4H++4e-0.21V(vs.SHE)
C+H2O＝CO+2H++2e-0.52V(vs.SHE)
corrosion of the carbon support can seriously affect the performance of the battery. Firstly, Pt particles fall off and agglomerate after the carbon carrier is corroded, so that the electrochemical active area of the catalyst is reduced; secondly, the corrosion of the carbon carrier can change the hydrophilicity and hydrophobicity and porosity of the catalyst layer structure, and simultaneously can separate the anode catalyst layer from the proton exchange membrane. In addition, the high potential at the time of the reverse polarity may also cause degradation of the binder (ionomer) in the catalytic layer, thereby further causing a change in the structure of the catalytic layer. Since the microporous layer (MPL) is adjacent to the catalytic layer, both have similar potentials, the anode MPL is also modified by the oxidation reaction that occurs during the reverse polarity process. In addition, when the reverse pole occurs, a large amount of heat is generated, and the heat can seriously aggravate the degradation of the proton exchange membrane to form holes, so that the open-circuit voltage is reduced, and even more, the cathode and the anode can be shorted through the holes to cause more serious accidents.
In summary, the performance and durability of the cell are seriously affected by the reverse polarity consequences, so how to monitor whether the reverse polarity of the proton exchange membrane fuel cell occurs and the degree of the reverse polarity, becomes a problem to be solved. In the search, some researchers have used voltage or voltage deviation to determine whether the reverse pole occurs (for example, chinese patent CN108254689A), but no example has been found so far in which the occurrence and the degree of the reverse pole are determined by detecting the internal resistance of the battery.
Disclosure of Invention
The invention aims to provide a monitoring proton exchange membrane fuel cellA method of reversing polarity, the method comprising the steps of: (a) firstly, carrying out voltage and internal resistance tests on a proton exchange membrane fuel cell to obtain a voltage-time curve, and determining a water electrolysis platform region and a cell internal resistance interval R corresponding to the region according to the voltage-time curve1(ii) a (b) Monitoring cell internal resistance R in the using process of proton exchange membrane fuel cell2And with R1And comparing to judge the degree of the reverse polarity of the battery.
Further, when R is2At R1When the fuel cell is in the normal working state, judging that the proton exchange membrane fuel cell is in the normal working state; otherwise, judging that the proton exchange membrane fuel cell has reverse polarity, and taking corresponding measures according to the situation.
Further, when R is2At R1When the range is within, the reverse pole of the proton exchange membrane fuel cell is judged, at the moment, the fuel cell can still be normally used, and measures to be taken are to adjust the operation parameters of the cell (such as increasing the flow of hydrogen, reducing the output current of the cell and the like) to force the reverse pole to be finished.
Further, when R is2Higher than R1And judging that the proton exchange membrane fuel cell is seriously reversed, and taking the measure of stopping using the proton exchange membrane fuel cell immediately.
Furthermore, the testing method of the internal resistance of the proton exchange membrane fuel cell is at least one of a high-frequency impedance method, a current interruption method and an alternating current impedance method.
Further, the proton exchange membrane fuel cell in step (a) needs to be fully activated before testing.
Further, the first plateau in the negative voltage in the voltage-time curve obtained in step (a) is determined as the water electrolysis plateau.
The principle of the invention is as follows: research finds that the internal resistance of the cell is in a certain interval range in the area of the water electrolysis platform in the reverse electrode process, and when the internal resistance of the cell is lower than the interval value, the fuel cell is in a normal working state; when the internal resistance value of the battery is in the interval, the battery starts to generate reverse polarity, but the battery is relatively safe, and the battery operation parameters can be adjusted to force the reverse polarity to be finished so as to reduce the damage to the battery; when the internal resistance value of the battery exceeds the interval, the serious pole reversal is shown to happen, and the battery needs to be stopped immediately, so that the larger accidents are avoided.

Detailed Description
In order to make those skilled in the art fully understand the technical solutions and advantages of the present invention, the following description is further provided with reference to the specific embodiments and the accompanying drawings.
Example 1
The fuel cell used in this example consisted of a cathode and anode gold plated stainless steel end plate, a cathode and anode graphite flow field plate, and a conventional membrane electrode. The active area of a conventional membrane electrode was 25cm2The membrane consists of a proton exchange membrane, an anode catalyst layer, a cathode catalyst layer and gas diffusion layers on two sides of the cathode catalyst layer and the anode catalyst layer. The proton exchange membrane is composed of perfluorosulfonic acid resin, the anode catalyst layer is formed by bonding Pt/C catalyst and resin, the cathode catalyst layer is formed by bonding Pt/C catalyst and resin, and the gas diffusion layer is mainly composed of a gas diffusion substrate (GDB) and a microporous layer (MPL).
All electricity before the reverse-pole experimentThe pool is fully activated, and the activation method comprises the following specific steps: the cell temperature before activation was set at 80 ℃, the cathode and anode relative humidity was 100%, the anode and cathode gas gauge pressures were 150kPa, and the anode and cathode gas excess coefficients were set at 1.5 and 2.5, respectively. When the activation is started, the output current of the battery is gradually increased, and the voltage of the battery is kept at about 0.5V. At high current densities (typically in excess of 2000 mA/cm)2) The battery performance no longer increases is the basis for determining that the battery has been sufficiently activated. After activation, the temperature of the cell was set to 65 ℃, the relative humidity of the cathode and anode was 100%, and the anode and cathode gases were at atmospheric pressure.
When the reverse pole experiment is started, firstly, 200mL/min of hydrogen and 800mL/min of air are respectively introduced into the anode and the cathode of the cell, and after 5min, the introduced hydrogen into the anode is switched into nitrogen. The battery is kept at 200mA/cm in the whole reverse pole experiment process2And the reverse polarity ending voltage is set to be-2.5V, and when the voltage of the battery is lower than the set value, the reverse polarity experiment is forcibly ended. The voltage and internal resistance of the fuel cell were recorded throughout the experiment, starting with the anode switched to nitrogen, and plotted to give the curve shown in figure 1.
As can be seen from fig. 1, the cell voltage initially drops only slightly because although the hydrogen introduced into the anode is switched to nitrogen, some residual hydrogen still exists in the gas pipe and inside the cell to participate in the electrochemical reaction, and the cell is maintained to operate normally. When the residual hydrogen is not enough to maintain the normal operation of the battery, the voltage rapidly drops to-0.9V, a reverse pole accident occurs, and meanwhile, the internal resistance is not changed greatly. A plateau (water electrolysis plateau) then appears briefly on the voltage-time curve, where the battery is generally considered to be relatively safe. The first plateau in the V-t curve at negative voltage is commonly referred to as the water electrolysis plateau, and for a standard membrane electrode (fig. 1), the approximate voltage range of the water electrolysis plateau is: -0.9V to-1.2V; for the counter electrode resistant membrane electrode in the subsequent embodiment (fig. 2), the approximate voltage range of the water electrolysis platform is: -0.7V to-1.0V.
As can also be seen from fig. 1, there is a slight change in the internal resistance of the cell in the plateau region. After the water electrolysis platform is finished, the voltage of the battery is rapidly reduced, and meanwhile, the internal resistance of the battery is also rapidly increased. After the water electrolysis platform, if the battery stops working in time due to the rapid voltage drop, the durability of the battery can be damaged irreversibly. It is thus clear that it is possible to estimate whether or not the reverse polarity occurs in the battery and the degree of progress of the reverse polarity by monitoring the internal resistance of the battery.
Example 2
The proton exchange membrane fuel cell selected for this example is similar to example 1, except that: a certain amount of iridium oxide (IrO) is doped into the anode catalytic layer on the basis of the conventional membrane electrode2) Thereby obtaining the anti-reverse electrode membrane electrode.
The results of the study of a proton exchange membrane fuel cell comprising an anti-reverse electrode membrane electrode as a subject were shown in FIG. 2, with reference to the method of example 1. The voltage-time and internal resistance-time curves of fig. 2 are substantially the same as those of the conventional membrane electrode of fig. 1, except that the water electrolysis plateau (-0.7V to-1.0V) takes much longer. As can be seen from fig. 2, monitoring the internal resistance of the battery can surely estimate whether or not the reverse polarity occurs in the battery and the degree of progress of the reverse polarity.
TABLE 1 internal resistance (m.OMEGA.. multidot.cm) of different membrane electrodes during the reversal of the polarity2) Comparison table
Table 1 shows the internal resistance values of different membrane electrodes at different stages during the reversal of the polarity of examples 1-2. It can be seen that there is a large difference in the internal resistance of the fuel cell before the water electrolysis stage begins, during the water electrolysis stage, and after the water electrolysis stage ends. For example, in the case of the anti-reverse electrode membrane electrode (example 2), if the internal resistance of the cell is less than 86m Ω · cm2If the battery is in a normal working state, the reverse polarity does not occur; if the internal resistance is between 86 and 180m omega cm2When the battery is reversed, the working condition of the battery should be adjusted or the battery should be shut down as soon as possible to prevent the battery from being damaged by the reversal; if of a batteryInternal resistance of over 180m omega cm2The battery should be immediately stopped to prevent a more serious accident.
Fig. 3 shows the change in the performance of the battery at different internal resistances in example 2. All cell performance was measured after the cell was fully activated, including cell performance after reversal. Performance test conditions: the cell temperature was set at 65 ℃, the cathode and anode relative humidity was 100%, the anode and cathode gas excess coefficients were set at 1.5 and 2.5, respectively, and the anode and cathode gases were both at atmospheric pressure. As can be seen from FIG. 3, when the internal resistance of the battery is 86 m.OMEGA.cm2When the reverse pole happens, the performance of the reverse pole battery is basically not reduced after the reverse pole is finished; when the internal resistance of the battery is 122m omega cm2When the battery is used, the performance of the battery is reduced to a certain degree (4% @1000 mA/cm)2) If the reverse polarity is continued until the internal resistance reaches 174m omega cm2When the battery performance is lowered, the battery performance is lowered by more than 10% @1000mA/cm2Meaning that the battery reaches the end of its life. When the internal resistance of the battery is 6360m omega cm2In time, the machine needs to be stopped immediately, so that larger accidents are avoided. This is because at this time, in addition to the serious degradation of the battery performance: (>15％@1000mA/cm2) The extra heat generated by the opposite pole may damage components such as the proton exchange membrane.
Example 3
In this example, the internal resistance maps of the anti-bipolar membrane electrode at each stage under different humidity conditions were studied, wherein each membrane electrode was tested under only one humidity condition. The preparation of the anti-reverse electrode membrane electrode can refer to example 2, and the detailed reverse electrode test refers to example 1.
FIG. 4 is a graph of internal resistance of each stage of the anti-reverse electrode membrane electrode under different humidity conditions. Relative humidity is a very important operating condition for the proper operation of a fuel cell. As is clear from fig. 4, the internal resistance of the battery under different humidity conditions during the reverse polarity process has substantially the same trend, and the difference therebetween is that the inflection points occur at different times. This is because the relative humidity affects the anti-reversal performance of the membrane electrode, but it is still possible to infer whether or not reversal occurs inside the cell and the degree of progress of reversal from the internal resistance value.
