Researchers in Switzerland have developed the world's first fuel cell based on formic acid, which is easier to store and transport than conventional hydrogen fuel cells that require hydrogen.This fuel cell is suitable for environmental protection in remote areas.
In the development of green energy, hydrogen as fuel is a key direction.Hydrogen burns without producing pollutants and is environmentally friendly, so hydrogen fuel cells have been developed in the past.But the problem is that the volume energy density of hydrogen is very low, and it is necessary to produce practical energy, which requires hydrogen gas to be bulky in the gaseous state, and there are many difficulties in storing and transporting hydrogen gas.
Formic acid can be produced by hydrogen and carbon dioxide, or by chemical reactions that release hydrogen, which can produce 590 litres of hydrogen.Formic acid is liquid in normal conditions, easy to store, transport and process, and global production is stable and has been widely used in agriculture, leather, rubber, chemical and pharmaceutical industries.
Researchers at the federal institute of technology in lausanne, Switzerland, have announced the development of a fuel cell based on formic acid.It mainly includes two parts, called the first part of the HYFORM ruthenium catalysts can be used to produce hydrogen from formic acid and the second part is called the PEMFC fuel cells, hydrogen power from part before use.
According to the introduction, the device is rated at 800 watts, about the same as the power required to charge 200 smart phones simultaneously.
This device also has the advantages of low maintenance cost and technology expansion, which can be applied to both domestic and industrial applications.As long as the supply of formic acid remains stable, the fuel cell can be used as an environmentally friendly energy for a long time.Researchers believe it is ideal for providing environmentally friendly energy in remote areas.
