phosphoric acid fuel cell
Quick Summary
A phosphoric acid fuel cell is a type of fuel cell that converts chemical energy into electrical energy through electrochemical reactions. These cells use phosphoric acid as the electrolyte, which is a syrupy liquid or crystalline solid.123
In a fuel cell, a fuel, such as hydrogen, is continuously supplied to one electrode, while oxygen from the air reacts at the other electrode. This process is more efficient than conventional energy conversion methods like internal combustion. Phosphoric acid itself is the most important oxygen acid of phosphorus and is used in various industrial applications, including fertilizers and food flavoring.13
