What does AFC mean in UNCLASSIFIED
AFC stands for Alkaline Fuel Cell, a power source technology that uses electrolytes combined with air and hydrogen to create an electrical current. This type of fuel cell has been around since the late 1800s but it has become increasingly popular in recent years due to its many applications and versatility. This article will provide an in-depth look at what AFC is, how it works, its benefits and drawbacks, and how it can be used as a source of renewable energy.

What Is an Alkaline Fuel Cell?
An alkaline fuel cell (AFC) is a type of electrochemical device that combines hydrogen atoms with oxygen molecules in a liquid electrolyte solution to create direct electrical current. The most common electrolyte solutions used are potassium hydroxide (KOH) or sodium hydroxide (NaOH). These solutions act as catalysts for the reaction between hydrogen and oxygen which results in electric current production and release of water vapor as a byproduct. The reaction is also known as "oxidation-reduction" or redox.
How Does It Work?
The reaction between hydrogen and oxygen molecules occurs on the surface of two different electrodes (the cathode and the anode) inside the alkaline fuel cell. On the cathode side, oxygen molecules are attracted towards positively charged ions generated by electrolysis; on the other hand, negatively charged electrons are attracted towards the anode where hydrogen molecules are present. This creates an electrochemical gradient within the cell allowing chemical reactions to occur resulting in electricity generation. During this process, water is produced as a byproduct which is later released into the atmosphere as water vapor.
Advantages & Disadvantages
The main advantages associated with AFCs are their efficiency, long life span (up to 20 years), low operating costs, and high reliability compared to conventional combustion technologies such as diesel generators or gasoline engines. Furthermore, they produce zero emissions which makes them environmentally friendly when compared to traditional power sources like coal or oil. However, their greatest limitation is their relatively low power output capacity which limits their potential applications — typically only small devices such as mobile phones or cameras require AFCs since larger machines need more power than what AFCs can currently provide.
Essential Questions and Answers on Alkaline Fuel Cell in "MISCELLANEOUS»UNFILED"
Alkaline fuel cells offer many advantages over traditional combustion technologies including higher efficiency and lower operating costs while producing no emissions whatsoever making them ideal for applications that require clean energy sources such as mobile phones and cameras. However, their low power output capacity limits their potential applications so they may not be suitable for larger machines requiring more electricity production than what these fuel cells can presently supply.
