The principle of hydrogen battery, what is the principle of hydrogen fuel cell?

Hydrogen Fuel Cell Principle:

An energy storage device that releases its internal energy when needed to meet demand; A hydrogen fuel cell, on the other hand, is an energy conversion device, a power generation device that provides the fuel needed for energy conversion when needed: hydrogen and oxygen, which can be released by the fuel cell by converting it into water and expelling it. In order to improve the efficiency of energy conversion in hydrogen fuel cells, the electrodes are often made of special porous materials to increase the contact area between the gas and the electrolyte and catalyze the chemical reactions that occur in the battery.

Hydrogen fuel cell is a substance that uses the reverse reaction of electrolysis of water to convert hydrogen, oxygen and other fuels into water and release energy, its hydrogen is located on the cathode, oxygen is located on the anode, and the electrolyte is located inside the battery, and the chemical energy is converted into electrical energy through this chemical reaction. Because its emissions are water, there are no other polluting emissions, so it is often called the green fuel hydrogen economy, because it also has the characteristics of low noise and high efficiency, it has been widely used in aerospace energy, automotive energy and other fields.

Hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy, and its principle is to react hydrogen and oxygen to supply energy to the car, and finally turn it into water and discharge it to the outside of the car.

Hydrogen fuel cells have the characteristics of low pollution, low noise and high efficiency, which are specified below.

1. Low pollution

Unlike conventional gasoline engines, vehicles powered by hydrogen fuel cells do not emit pollutants such as COX, NOX, SOX gases and dust while driving, so they are less polluting and have little to no pollution.

2. Low noise:

Hydrogen fuel cell vehicles produce relatively low noise when driving, so they can improve the comfort of drivers and passengers to a certain extent.

3. High efficiency

The power generation efficiency of hydrogen fuel cells can reach more than 50%, and it can directly convert chemical energy into electrical energy, so the power transmission efficiency is relatively high, making the power of the car more prominent.

As of August 2019, there are not many mass-produced hydrogen fuel cell vehicles on the market, because their technology is not particularly stable, and the specific situation needs to be further tested by the market. Therefore, the development of hydrogen fuel vehicles still has a long way to go.

Hydrogen energy. The basic principle of a fuel cell is the reverse reaction of electrolysis of water, which supplies hydrogen and oxygen to the anode and cathode, respectively, and the hydrogen diffuses outward through the anode and electrolyte.

After the reaction occurs, the emitted electrons reach the cathode through an external load.

The basic principle of hydrogen fuel cells is the reverse reaction of electrolysis of water, which supplies hydrogen and oxygen to the anode and cathode respectively, and after the hydrogen diffuses outward through the anode and reacts with the electrolyte, the electrons are released to reach the cathode through the external load.

Hydrogen fuel cells do not pollute the environment, it is through electrochemical reactions, rather than using combustion (gas, diesel) or energy storage (battery) methods, the most typical traditional backup power scheme, combustion will release pollutants such as COX, NOX, SOX gas and dust. Fuel cells produce only water and heat. If hydrogen is produced from renewable sources, the entire cycle is a completely non-hazardous process.

Strictly speaking, a hydrogen fuel cell is a power generation device, like a power plant, an electrochemical power generation device that converts chemical energy directly into electrical energy. In addition, the electrodes of hydrogen fuel cells are made of special porous materials, which is a key technology of hydrogen fuel cells, which not only provides a large contact surface between gas and electrolyte, but also plays a catalytic role in the chemical reaction of the battery. The fuel cell runs quietly, with a noise level of only about 55 dB, which is equivalent to the level of normal conversation.

This makes the fuel cell suitable for indoor installations, or outdoors where noise is limited.

The working principle of hydrogen fuel cell vehicle is: hydrogen is sent to the anode plate (negative electrode) of the fuel cell, through the action of the catalyst (platinum), one of the electrons in the hydrogen atom is separated, and the hydrogen ion (proton) that loses the electron passes through the proton exchange membrane and reaches the cathode plate (positive electrode) of the fuel cell, while the electron cannot pass through the proton exchange membrane, and this electron can only pass through the external circuit to reach the fuel cell cathode plate, thereby generating current in the external circuit. After the electrons reach the cathode plate, they recombine with oxygen atoms and hydrogen ions to form water.

Since the oxygen given to the cathode plate can be obtained from the air, as long as the anode plate is constantly given hydrogen, the cathode plate is given air, and the water (vapor) is taken away in time, electricity can be continuously supplied. The electricity emitted by the fuel cell is supplied to the motor through the inverter, controller and other devices, and then the wheels are rotated by the transmission system and drive axle to make the vehicle drive on the road. Thanks to the addition of such a power generation device, the cruising range of hydrogen fuel cell vehicles has been significantly improved, and the hydrogen refueling time is generally only 5 minutes, which is many times faster than the charging time.

A hydrogen fuel cell is a power generation device that converts the chemical energy of hydrogen and oxygen directly into electrical energy. It works by reacting hydrogen and oxygen to provide energy to the car, which is finally converted into water and discharged out of the car.

Hydrogen fuel cells have the characteristics of low pollution, low noise, and high efficiency, which are detailed below.

1.Low pollution:

Unlike conventional fuel engines, cars powered by hydrogen-fueled batteries emit pollutants such as COX, NOX, SOX gases and dust during driving, so they are less polluting and have almost no pollution.

2.Low noise:

Hydrogen fuel cell vehicles have relatively low noise levels when driving, so they can improve the comfort of drivers and passengers to a certain extent.

3.High efficiency:

The power generation efficiency of hydrogen fuel cells can reach more than 50%, which can directly convert chemical energy into electrical energy, so the power transmission efficiency is relatively high, making the power of the car more prominent.

As of August 2019, there are not many mass-produced hydrogen fuel cell vehicles on the market, because their technology is not particularly stable, and the specific situation needs to be further tested by the market. Therefore, the development of hydrogen fuel vehicles still has a long way to go.
