1, hydrogen energy still has a long way to go, and hydrogen energy is the real new energy in the future. Unlike coal, oil and natural gas, hydrogen can exist in and be extracted from water and air, which are almost infinite and will not produce any pollution. But I don't know that there is still a more critical subdivision of hydrogen energy than the market, and the future market space is expected to exceed10 billion.
2. Proton exchange membrane fuel (PEM) is the core component of PEMFC, which is different from the membrane used in general chemical power supply. Proton exchange membrane fuel cell has become the most competitive clean alternative power source for gasoline internal combustion engines. The materials used as PEM should meet the following conditions: good proton conductivity, small electroosmosis of water molecules in the membrane, as small as possible gas permeability in the membrane, good electrochemical stability, good dry-wet conversion performance, certain mechanical strength, good processability and reasonable price.
3. Proton exchange membrane fuel cell has the advantages of low working temperature, fast start-up, high specific power, simple structure and convenient operation, and is recognized as the first choice of energy for electric vehicles and fixed power stations. Inside the fuel cell, the proton exchange membrane provides a channel for the migration and transportation of protons, so that protons can reach the cathode from the anode through the membrane, and form a loop with the electron transfer of the external circuit to provide current to the outside world. Therefore, the performance of proton exchange membrane plays a very important role in the performance of fuel cells, and its quality directly affects the service life of the cells. The development goal of fuel cell vehicles in 2030 is 100 vehicles, which will bring about a monthly demand of 26.4 million square meters and a market space of 132 billion yuan. There are three positive directions.
