Fuel Cell and Hydrogen Energy
Fuel Cell Basics
Fuel Cell Overview
Fuel cells are electrical generation devices that utilize a chemical reaction to unleash a fuel’s latent energy. They are clean, quiet, efficient, and scalable, allowing them the versatility in nearly every power application. Fuel cells are being deployed today globally in portable, stationary, and transportation applications.
As fuel cells generate electricity through a chemical reaction, rather than combustion, they do not produce harmful emissions such as sulfur oxides, nitrous oxides, mercury or soot, and dramatically reduce carbon emissions compared to traditional forms of power generation.
Hydrogen is the most common fuel used in fuel cells and is also the least harmful to the environment. The only byproducts of the oxidation reaction between hydrogen and oxygen are electricity, heat and water vapor. In many cases, this heat can be recaptured for use in industrial or residential applications, greatly increasing the system’s total efficiency.
There are several types of fuel cells, each possessing its own set of benefits. This list includes Proton Exchange Membrane Fuel Cells (PEMFCs), Direct Methanol Fuel Cells (DMFCs), Solid Oxide Fuel Cells (SOFCs), Phosphoric Acid Fuel Cells (PAFCs), Molten Carbonate Fuel Cells (MOFCs), and Alkaline Fuel Cells (AFCs). These fuel cells are differentiated by their unique electrolyte configurations.
