Before discussing the new energy vehicles and hydrogen fuel cell rubber seals, let's first consider the existing problems of various types of existing vehicles.
Since the industrial revolution, cars have been around for over a hundred years. Various issues such as comfort, safety, speed, etc. have been continuously improved. However, the energy problem has not been completely solved. What are these problems?
Traditional fuel vehicles use gasoline/diesel, which is non-renewable and polluting. Pure electric vehicles have problems with short range and long charging time. Hybrid vehicles mainly still use fuel, but have slightly lower energy consumption.
As global climate warming intensifies, more and more car manufacturers have realized the unsustainability of traditional fuel vehicles. Seeking new energy as a power source is urgent. It can be said that whoever solves the energy problem will have an absolute advantage in the future competition.
Under such circumstances, fuel cells came into people's attention. Unlike ordinary batteries, it is a generator that converts the chemical energy of fuels (such as methanol/gasoline, etc.) into electrical energy. It does not store electricity first and then release it when needed. Using hydrogen as the fuel, the energy conversion rate reaches 60%-80%, which is 2-3 times that of traditional internal combustion engines. Moreover, the sources of hydrogen production are abundant, including electrolysis of water, methanol, ethanol, and natural gas. It was actually widely used in the aerospace field a long time ago, but due to the immature technologies in hydrogen production, storage, and application at that time, it did not become widely applied. Especially, the rubber sealing gasket for hydrogen fuel cells at that time did not have a particularly good solution.
After several decades of development, hydrogen fuel cells have made significant progress. Especially Toyota, which has filed over 10,000 patents related to hydrogen fuel cells, and has released the world's first mass-produced hydrogen fuel cell vehicle, the Mirai. With a 5-kilogram hydrogen fuel tank, it can travel 500 kilometers.
Now let's talk about the requirements for the hydrogen fuel cell rubber gasket, which is one of the core components in hydrogen fuel vehicles:
1. Insulation: The fuel cell stack is composed of multiple individual cells. If a short circuit occurs, the consequences would be unimaginable.
2. Gas barrier: It must ensure the sealing of oxygen and hydrogen, and there should be no leakage.
3. The material should be able to absorb shocks and vibrations, as it operates in a vehicle and driving bumps are inevitable.
4. It should have acid resistance and high temperature resistance, which are the most basic requirements.
Of course, there are many other requirements. Due to commercial reasons, I'm sorry that I can't list them all. Our company designed and produced the fluorine rubber gasket for the hydrogen fuel cell used in BMW cars in 2017, and has been cooperating with them until now. You can see our company's strength from the cooperating customers.
