Description

Novel fuel cell membrane electrode and preparation method thereof
Technical Field
The invention relates to an electrode and a preparation method thereof, in particular to a novel fuel cell membrane electrode and a preparation method thereof.
Background
The key components of a pem fuel cell stack are the bipolar plates and the membrane electrodes, both of which account for approximately 80% of the material cost of the entire stack. Meanwhile, the cooperation between the bipolar plate and the membrane electrode directly influences the performance of the electric pile. Therefore, how to reasonably match the two has a profound influence on the cost performance of the stack product.
One set of bipolar plates contains a cathode and an anode face. The plate reaction zone consists of complex and precise recessed flow channels and raised ridges. From the cross-section of the plate, a regular alternating distribution of flow channels and ridges can be observed. The existing CCM is mostly produced by uniformly transferring platinum catalyst slurry onto a proton membrane in a spraying or coating manner. There is no difference between the distribution of the catalyst on the proton membrane corresponding to the flow channel region and the ridge region of the plate.
The material cost of the membrane electrode typically accounts for about 65% of the cost of the stack, and is a significant portion of the stack cost. The membrane electrode is formed by bonding a Catalyst Coated Membrane (CCM), a sub-gasket, a diffusion layer and a frame according to the design size.

Coating the first slurry on the whole area of the flow channel area and the ridge area on the two surfaces of the CCM to prepare the material with the active area of 370cm2The control membrane electrode of (1).

The membrane electrode test method comprises the following steps:
the performance evaluation of the membrane electrode takes current density as a reference; the current density is the current at the rated voltage of each membrane electrode divided by the area of the reaction zone and is A/cm2. For example, at a monolithic voltage of 0.65V, the current density is 2.0A/cm2However, if only the flow path area in the reaction zone is considered (usually 50%), the actual current density in the above reaction zone is 4.0A/cm2I.e. only 50% of the membrane electrode is directly involved in the electrochemical reaction.
Prepared according to example 1, example 2, comparative example 1 and comparative example 2, and the active area is 370cm2The membrane electrode of (1).
2 membrane electrodes and 3 bipolar plates were assembled into a 2-piece stack for testing on a 5kW test bed. A total of 3 small stacks were initially made. After 30 minutes of low current humidification and break-in, the test was performed under the following conditions:
Figure 234188DEST_PATH_IMAGE002
test results
1. The membrane electrodes of example 1 were combined into small stacks-1 and subjected to a stability test under the above conditions for 30 minutes, with the monolithic average voltage of the stack adjusted to 0.65V and the output current density recorded to 1.08A/cm 2.
2. The membrane electrodes of example 2 were combined into small stacks-2 and tested for stability under the above conditions for 30 minutes, with the monolithic average voltage of the stack adjusted to 0.65V and the recorded output current density of 1.12A/cm 2.
3. The membrane electrode of comparative example 1 was formed into a small stack-0, and subjected to a stability test under the above conditions for 30 minutes, the monolithic average voltage of the stack was adjusted to 0.65V, and the output current density was recorded to be 1.11A/cm 2.
4. The membrane electrode of comparative example 2 was formed into a small stack-3. The design objective of the mini-stack-3 was to verify the role of the second paste in the current transfer process.The stability test is carried out for 30 minutes under the above conditions, the average voltage of the single chip of the galvanic pile is adjusted to be 0.65V, and the recorded output current density is 0.87A/cm2。
The above experimental results show that the membrane electrode designed according to the present invention has similar test results to those of comparative example 1, although the noble metal platinum content of the membrane electrode of the present invention is 50% of that of comparative example 1. The advantages of example 2 are evident. Comparative example 2 also shows that the conductive coating on the corresponding flow channel ridge pattern has a significant effect on electron transfer, and the effect of the conductive effect of the ridge on the membrane electrode performance must be considered in membrane electrode design.
The flow channels are adapted to facilitate the flow of cathode and anode gaseous reactants for carrying out the electrochemical reaction promoted by the catalyst in the membrane electrode. According to the research result of the invention, the ridge back of the polar plate has two functions. The first is to support the membrane electrode to maintain the mechanical stability of the membrane electrode in high pressure reaction; the second is electrical conduction, which transfers electrons at the surface of the membrane electrode catalyst to the bipolar plate. Therefore, the membrane electrode part in the flow channel area is the main power for supporting the electrochemical reaction, but the membrane electrode in the ridge area has no direct contribution to the electrochemical reaction, and the indirect contribution is to transmit electrons of the catalyst surface as reactants or products to a series circuit consisting of bipolar plates in time to form a closed loop of current.

The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the content of the embodiment. It will be apparent to those skilled in the art that various changes and modifications can be made within the technical scope of the present invention, and any changes and modifications made are within the protective scope of the present invention.
