UPDATED: 03/14/2023 Fuel cells: What they are, how they work, types, advantages, what they are for Image. Fuel cells are electrochemical devices that convert the chemical energy of a fuel into electrical energy through a redox reaction. This technology has the potential to revolutionize the way we produce and consume energy, offering a clean and efficient source of energy. In this article, we will explore what fuel cells are, how they work, the different types of fuel cells, their advantages and applications.
What are fuel batteries? They are electrochemical devices that generate electricity from the reaction between a fuel and an oxidant in the presence of a catalyst. The reaction produces electrical energy, heat and water as a byproduct. Unlike internal combustion generators, fuel cells do not burn fuels and therefore do not produce harmful UK Phone Number emissions. How do fuel cells work? They consist of two electrodes separated by an electrolyte. The positive electrode is called the cathode, while the negative electrode is called the anode. The fuel, which can be hydrogen (H 2 ), methane (CH 4 ), ethanol (C 2 H 5 OH), or other fuels, is supplied to the anode, while the oxidant, which is usually oxygen (O 2 ) from the air , is supplied to the cathode.
The electrochemical reaction between the fuel and the oxidant at the electrodes produces electrons and hydrogen ions. Electrons flow through an external circuit to produce electricity, while hydrogen ions pass through the electrolyte to the cathode, where they combine with the oxidant and produce water as a byproduct. Types of fuel cells. There are several types of fuel cells, each with its own advantages and limitations. Some of the most common types are: Hydrogen-oxygen fuel cells (PEM fuel cell) : This type uses hydrogen and oxygen to generate electricity. It is one of the most promising technologies due to its high efficiency and low emissions. Additionally, it is capable of quick starting and stopping, making it ideal for electric vehicles.
