Description
Technical Field
The invention relates to the technical field of proton exchange membrane fuel cells, in particular to a method for accelerating evaluation of durability of a proton exchange membrane for a fuel cell.
Background
Proton Exchange Membrane Fuel Cells (PEMFCs) are considered to be the most promising for applications in the fields of vehicle-mounted power systems and stationary power stations because of their advantages of compact structure, high power density, environmental protection, no pollution, and room-temperature start-up. The proton exchange membrane, which is a key material of the PEMFC, mainly plays roles of conducting protons and separating cathode and anode gases, and its durability directly affects the durability of the entire PEMFC.
The durability of the proton exchange membrane is divided into two aspects of mechanical durability and chemical durability, wherein the mechanical durability mainly refers to gas barrier attenuation caused by swelling and shrinking of the proton exchange membrane due to different water content in the membrane during the operation process of the fuel cell; the chemical durability mainly refers to the reduction of gas barrier property and the reduction of proton conduction capability caused by the fracture of a polymer in a proton exchange membrane due to the attack of free radicals during the operation of a fuel cell.
In the current research, researchers mostly adopt a mechanical durability evaluation method and a chemical durability evaluation method for a proton exchange membrane, which are published by the united states department of energy (DOE) [1 ]. The mechanical durability evaluation method adopts the steps of introducing air into two sides of a Membrane Electrode Assembly (MEA) made of a proton exchange membrane to be evaluated, switching the relative humidity (from 0% RH to 100% RH) of the air every 2min, and performing 20000 cycles in total. The chemical durability evaluation method adopts the steps of respectively introducing hydrogen and air into two sides of an MEA (membrane electrode assembly) made of a proton exchange membrane to be evaluated, maintaining the relative humidity of a cathode and an anode at 30%, and continuously testing for 200 h.
Although DOE proposes a durability evaluation method for the mechanical durability and the chemical durability of the proton exchange membrane, respectively, the DOE has a large defect in the practical application process. Firstly, the simple evaluation of the mechanical durability and the chemical durability of the proton exchange membrane is meaningful for scientific research and is helpful for corresponding optimization of the proton exchange membrane material, but the method cannot provide a means for comprehensive evaluation, because the mechanical attenuation and the chemical attenuation of the proton exchange membrane exist simultaneously in the practical application environment of the proton exchange membrane, and the two have obvious coupling phenomena. Specifically, on one hand, the chemical decay rate of the proton exchange membrane is significantly accelerated along with the decrease of the mechanical properties of the proton exchange membrane, because the decrease of the gas barrier properties caused by the decrease of the mechanical properties leads to the gradual increase of the amount of air passing through the proton exchange membrane, the air reaches the hydrogen side and then undergoes a reduction reaction through a two-electron reaction mechanism to generate more hydroxyl radicals, and the radicals attack the high molecular polymer to accelerate the chemical decay process of the proton exchange membrane. In addition, when the DOE is adopted for proton exchange membrane material selection, the inventor finds that although a certain proton exchange membrane can simultaneously meet the requirements of mechanical durability and chemical durability specified by the DOE, the durability of the proton exchange membrane applied to a fuel cell can only reach about 2000h, and the proton exchange membrane is far from meeting the requirements of commercial application.
For the commercial application of PEMFCs, not only the performance requirements are satisfied, but also good stability is required. The durability of the proton exchange membrane, which is the primary site where the ion transport process occurs, directly affects the performance and stability of the overall fuel cell.
However, the durability evaluation using the normal operation condition of the fuel cell requires too long time, which is very disadvantageous to the PEMFC development process, and thus a method for rapidly evaluating the durability of the proton exchange membrane for the fuel cell is urgently required.

s1, preparing a full-size membrane electrode assembly. The proton exchange membrane with the size completely consistent with that in the practical application scene is adopted for durability evaluation, so that the durability change caused by the size change can be avoided. By adopting the proton exchange membrane, catalyst layers are prepared on two sides of the proton exchange membrane according to an actual shaping process, and a full-size Membrane Electrode Assembly (MEA) is prepared by matching a corresponding Gas Diffusion Layer (GDL) and a frame.
And S2, assembling the fuel cell by utilizing the full-size membrane electrode assembly, introducing hydrogen into an anode side flow field of the fuel cell, and introducing air into a cathode side flow field of the fuel cell.
And S3, controlling the battery temperature according to the general operation state of the fuel battery. The cell temperature is preferably controlled to 80 c, which is the normal operating temperature of the fuel cell.
And S4, synchronously switching the humidity of the input hydrogen and the air according to a fixed time interval, wherein the relative humidity of the hydrogen and the air is switched between 0% RH and 100% RH.
And S5, acquiring the hydrogen permeation current and the ventilation time of the fuel cell in the evaluation process until any one of the hydrogen permeation current and the ventilation time reaches the termination condition of the preset test.
And S6, drawing a variation curve of the hydrogen permeation current and the ventilation time in the test process, and obtaining an evaluation result of the durability of the proton exchange membrane according to the variation curve of the hydrogen permeation current.
The scheme and effect of the present invention will be further explained by specific application examples.
(1) Adopts a proton exchange membrane with the size completely consistent with that in the practical application scene, uses a Pt/C catalyst and has the mass fraction of 0.5 percent
Preparing slurry according to the mass ratio of 1:7, preparing a catalyst layer on the surface of a proton exchange membrane (or a gas diffusion layer) by using the slurry, matching the corresponding gas diffusion layer and a frame after spraying, and preparing a full-size Membrane Electrode Assembly (MEA).
(2) And (2) assembling single cells by adopting the MEA (1), assembling the single cells as shown in figure 2, connecting the single cells into a fuel cell testing system, respectively introducing hydrogen and air into a cathode and an anode, and adjusting relevant parameters (such as cell temperature, gas flow rate, gas relative humidity and the like) to normal working conditions.
(3) The humidity of hydrogen and air was switched every 2min, from completely dry gas (relative humidity of 0% RH) to saturated humidified gas (relative humidity of 100% RH), and the humidity of hydrogen and air was changed in synchronization.
(4) The fuel cell is tested for hydrogen permeation current and gas permeation time at regular intervals, preferably at 46h intervals.
(5) The hydrogen permeation current testing method comprises the following steps: the method comprises the steps of keeping hydrogen of the anode gas of the battery unchanged, switching the cathode gas from air to nitrogen to purge the battery, reducing the open-circuit voltage (OCV) of the battery to about 0.1V, and performing cyclic voltammetry scanning operation on the battery by adopting a constant potential rectifier, wherein the scanning range is 0.1V-0.6V, the scanning speed is 0.002V/s, and the current density corresponding to 0.45V is the hydrogen permeation current.
(6) The air permeability time test method comprises the following steps: the total volume of gas that permeated from the anode side to the cathode side was tested for the time required to reach 0.5ml while maintaining the gas pressure in the anode side flow field at 100 kPa.
(7) When the hydrogen permeation current is more than 10mA/cm2Or stopping the experiment when the air permeation time is less than 1 s.
(8) Durability tests were performed on the proton exchange membranes # 1 and # 2 using the above method, and the results of the hydrogen permeation current and the permeation time test in the durability process are shown in fig. 3 and fig. 4, for example.
The comparison between the two samples is used here to illustrate the effectiveness of the method, with differences in the results obtained for the samples of different durability. If a single sample is evaluated, the end point of the experiment is determined according to the criteria described in item (7).
(9) From the results of fig. 3-4, it can be seen that when the permeation time is less than 1s, the hydrogen permeation current of the proton exchange membrane does not change significantly, and therefore, the change of the gas barrier property of the proton exchange membrane cannot be visually represented by using the hydrogen permeation current. As can be seen from the results of FIG. 4, the gas permeation time of the 1# proton exchange membrane after 368h acceleration test is less than 1 s; and the air permeation time of the 2# proton exchange membrane is less than 1s after the 2# proton exchange membrane is subjected to the 2162h accelerated test, namely, the 2# proton exchange membrane can endure the accelerated evaluation for a longer time. Therefore, the 2# proton exchange membrane has durability far better than that of the 1# proton exchange membrane.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
