Description
Technical Field
The invention relates to a device for quickly testing a membrane electrode of a fuel cell, in particular to a device for quickly testing the membrane electrode on line by a fuel cell testing platform.
Background
A fuel cell is a power generation device that can directly convert chemical energy of a fuel and an oxidant into electrical energy. Whether industrial production or scientific research is carried out, the fuel cell is tested. The membrane electrode is a key structure of the fuel cell operation, and the performance test of the membrane electrode is also an important ring in the fuel cell test. The membrane electrode is tested by putting the membrane electrode into a designed clamp for pre-assembly, assembling the membrane electrode into a single cell by using a screw rod matched with a press and the like, and then testing the single cell by using a fuel cell test bench, wherein the process is complicated. Therefore, if the assembly of the single battery and the fuel cell test bench are combined into a platform, the test efficiency can be greatly improved.
In testing of fuel cells, testing tasks that are often required to be performed for membrane electrodes include: 1) membrane electrode activation and performance test under the full current standard working condition are realized, and meanwhile, the electrochemical impedance test of the membrane electrode is carried out on line, and the performance of the membrane electrode is represented by a polarization curve; 2) at H2/N2Measuring the active area and hydrogen permeability of the MEA by cyclic voltammetry under the condition; 3) at H2/O2MEA oxygen reduction reactivity was tested under conditions. Implementing these tests requires that the test equipment contain the following structure: the system comprises a cathode and anode gas supply subsystem, a galvanic pile cooling subsystem, a humidification subsystem, a backpressure control subsystem and an electrochemical workstation. In addition, before the membrane electrode test, the tested membrane electrode is assembled into a single cell by using a test fixture. The test fixture structure comprises an end plate, a current collecting plate, a cathode plate and an anode plate and a bolt. The test fixture can provide a cathode and anode gas flow passage and a cooling water flow passage, and provide a cathode and anode gas interface, a cooling water interface and a current output interface which are connected with the test bench. The assembly process requires the electrical connection of the membranesAll the layers of the pole and the test fixture are laminated together, pressure is applied by a press to assist assembly, and finally bolts are used to ensure that the assembled pressure forms a single cell. Sometimes, for the test of the membrane electrode, the magnitude of the assembling force and the assembling displacement of the single cell have different requirements, so that the traditional process of separately assembling the single cell and the cell test is more complicated and consumes longer time.
For example, the Chinese patent "a fuel cell membrane electrode performance testing device and application" (publication number: 109946519A) discloses a performance testing device for a fuel cell membrane electrode, which comprises an electrode quick mounting component, a quick loading component and a temperature control component. The rapid electrode installation component is used for rapidly installing the membrane electrode to be tested, the rapid loading component is used for rapidly providing specified pressure for the membrane electrode to be tested, and the temperature control component is used for providing specified reaction temperature for the membrane electrode. When the pressure and temperature of the membrane electrode reach the specified temperature, reaction gas can be introduced to measure the performance of the membrane electrode.
In summary, for the fuel cell membrane electrode test, the conventional membrane electrode performance test procedure is complicated, and a lot of unnecessary resource waste is caused.
