Hydrogen fuel cell are power generation devices that directly convert the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzing water, which supplies hydrogen and oxygen to the anode and cathode respectively. Hydrogen diffuses outward through the anode and reacts with the electrolyte, releasing electrons to reach the cathode through an external load.
The difference of hydrogen fuel cell and Dry cell,Accumulator cell
Dry batteries and accumulators are energy storage devices that store electrical energy and release it when needed; Strictly speaking, hydrogen fuel cells are a power generation device, like power plants, which directly convert chemical energy into electrical energy through electrochemical power generation. In addition, the electrodes of hydrogen fuel cells are made of specially made porous materials, which is a key technology of hydrogen fuel cells. It not only provides a large contact surface for the gas and electrolyte, but also plays a catalytic role in the chemical reactions of the battery.
Advantages of Hydrogen Fuel cell
1.pollution-free
Fuel cells are environmentally friendly. It is achieved through electrochemical reactions rather than combustion (gasoline, diesel) or energy storage (battery). – The most typical traditional backup power solution. Combustion releases pollutants such as COx, NOx, SOx gases, and dust. As mentioned above, fuel cells only produce water and heat. If hydrogen is generated through renewable energy sources (such as photovoltaic panels and wind power generation). The entire cycle is a process that completely eliminates the emission of harmful substances.
2.No noise
Fuel cells operate quietly, with a noise level of only about 55dB. Which is equivalent to the level of normal conversation among people. This makes fuel cells suitable for indoor installation or in areas with limited noise outdoors.
3.high efficiency
The power generation efficiency of fuel cells can reach over 50%.It is determined by the conversion properties of fuel cells. They directly convert chemical energy into electrical energy without the need for intermediate conversion between thermal and mechanical energy (generators).
Besides fuel cell,we also supply hydrogen production machine
