Description
Technical Field
The invention relates to the technical field of new energy, in particular to a hydrogen fuel cell using a graphene black phosphorus alkene heterojunction as an electrode and a preparation method thereof.
Background
In the 60's of the 20 th century, hydrogen fuel cells have been successfully used in the aerospace field. The small and large capacity device is installed in the Apollo spacecraft which travels to and from space and earth. After the 70 s, hydrogen fuel cells were soon being used for power generation and automotive applications as people continually master a variety of advanced hydrogen production technologies. Large power stations, whether hydroelectric, thermal or nuclear, send the generated electricity to the grid, which delivers it to the users. However, the load of each power consumer is different, so that the power grid sometimes shows a peak and sometimes shows a valley, which may result in a power failure or unstable voltage. In addition, about 70% of the combustion energy of the conventional thermal power station is consumed by large equipment such as a boiler and a turbine generator, and a large amount of energy and a large amount of harmful substances are also consumed during combustion. The hydrogen fuel cell is used for generating electricity, chemical energy of fuel is directly converted into electric energy, combustion is not needed, the energy conversion rate can reach 60% -80%, pollution is low, noise is low, and the device can be large or small and is very flexible.
2D material with atomic layer thickness due to its differenceThe superior properties of bulk materials have been extensively studied, such as graphene, MoS2And so on. In recent years, another new 2D material, namely, a few-layer black phosphorus alkene, can be prepared by a mechanical stripping method under experimental conditions and is widely noticed. Black phosphorus is a crystal with metallic luster, can be converted from white phosphorus or red phosphorus, has a direct semiconductor band gap and shows the characteristics related to the number of layers, and the electron mobility of few-layer black phosphorus alkene is 1000cm2the/Vs also has very high leakage current modulation rate, so that the application of the/Vs in future nano-electronic devices has great potential. In addition, because the material is a direct band gap, the optical properties of the material have great advantages compared with other materials, and the material is one of the hot spots of the research on the novel two-dimensional material at present.
Most of the current fuel cells are hydrogen fuel cells, which are bulky and have low combustion efficiency. The low efficiency is mainly found by analysis that the chemical reaction rate of the cathode and anode of the fuel cell is too slow. The large volume is mainly caused by the large thickness of the cathode and the anode. The appearance of two-dimensional materials provides a new idea for fuel cells, graphene has high electron mobility, and black phosphorus has a large surface-to-volume ratio. The excellent characteristics of the two can be combined to form the cathode and anode of the fuel cell, which can provide higher reaction rate. And the two-dimensional material is a single-layer structure, the number of layers of the required material can be selected according to the performance of the battery, so that the cathode and the anode of the battery are very thin, and the whole volume of the battery is minimized finally.
