The difference between fuel cells and lithium batteries is:
1. Different principles: fuel cells are batteries that generate electrical energy by reacting fuel (such as hydrogen) and oxygen reactions; lithium batteries are batteries made by lithium metal or lithium alloy as positive and negative poles.
2. Different ability density: The energy density of fuel cells is much higher than lithium batteries.
3. Different charging speed: The charging speed of the fuel cell is faster than the lithium battery, but the number of charging times is less than the lithium battery.
4. Different service life: The service life of fuel cells is longer than lithium batteries, but its maintenance cost is higher than lithium batteries.
5. Fuel cells cannot be stored, and lithium batteries can store electrical energy.
A fuel cell is a new type of power generation device that can convert chemical energy into electrical energy. It can convert chemical energy into electrical energy, but it does not produce any harmful exhaust gas. It is a clean power generation technology.
The fuel cell consists of an electrolyte room, an electrode room, and a membrane room, and they together form a closed system. When the fuel (such as hydrogen) flows into the electrolyte, the oxidation reaction of the electrolyte, the hydrogen is oxidized into a hydrogen ion, and the oxygen is restored to oxygen ions. Electricity.
The advantage of fuel cells is that it can effectively use energy, has the advantages of high efficiency, low pollution, renewable, and can be used in the fields of automobiles, ships, and household appliances, which greatly improves energy utilization efficiency and reduces environmental pollution.
Lithium battery is a rechargeable battery, which has the characteristics of high energy density, light quality, long life, good low temperature performance, safety and reliability.
The structure of lithium batteries includes positive poles, negative materials, electrolytes and shells. The positive electrode material is generally carbon material. The negative electrode material is generally lithium alloy. The electrolyte is a solvent containing lithium ions. The shell is a waterproof, flame retardant, and high -temperature -resistant plastic.
The application of lithium batteries is very wide. It can be used for power supply such as mobile phones, digital cameras, MP3s, laptops, motorcycles, electric vehicles, and drones.
