What is a Micro Fuel Cell?

This battery uses platinum as an electrode and sulfuric acid as an electrolyte, and generates electricity through a hydrogen-oxygen reaction. The battery is dead and you only need to change the fuel cartridge. With the rapid development of thermal motor technology, fuel cell technology is gradually forgotten by people. It was not until the 1960s that the development of rockets and automobiles prompted people to re-investigate fuel cells. Since the 1990s, the automotive industry has also become interested in non-polluting fuel cells. The high requirements for collected power and standby time have also provided new fields of application for fuel cells.

A micro fuel cell is a power source used in electronic equipment that converts chemical energy into electrical energy. Fuel cells operate by oxidizing flammable fuels such as hydrogen or alcohol. These energy sources are used in large quantities in motor vehicles. Most of these devices use hydrogen. Recently, smaller fuel cells have been developed for use in digital cameras, portable radios and laptops. These devices use fuels other than hydrogen, most notably formaldehyde, a form of alcohol.

Fuel cells are different from traditional electrochemical cells. Both technologies involve the conversion of chemical energy into electrical energy. However, the traditional battery uses a reaction between the metal and the electrolyte, and the chemical properties of the metal and the electrolyte change over time, and the fuel cell burns its fuel, leaving only an empty shell in the end.

A common example of a conventional electrochemical battery is a lead-acid battery. Another example is a lithium-ion battery. Some traditional batteries can be recharged by connecting to an external power source. Others must be discarded after use and cannot be reused. Correspondingly, the fuel cell only needs to be refilled with fuel before it can be used again. Recharging traditional batteries takes hours, and changing a fuel cartridge takes only seconds.

The demand for micro fuel cells in the world market is expected to increase with the improvement of technology and cost reduction in the coming years. [1]
Invented by Sir Willian Grove in 1839. The two shortcomings of fuel cells have been restricting its development. First of all, its price is very expensive, which limits its use. Only used for space missions or remote areas for power generation. Secondly, hydrogen is a highly volatile flammable gas, which is very difficult to store.
The French Atomic Energy Commission's Energy Technology Innovation Laboratory (Liten) in Grenoble has achieved a pioneering initiative to reduce fuel cells to the size of a coin.
In the field of mobile phones, the disadvantage of expensive micro fuel cells is not very prominent. Moreover, researchers have developed micro fuel cells that are 2 cm square and 0.5 mm thick. The battery has entered production testing in France. The use of this battery can make the phone last 5 times longer.
