Study Notes
Fuel Cell Basics
- The main function of a fuel cell is to convert chemical energy into electrical energy.
- Sir William Robert Grove is generally credited with inventing the fuel cell in 1839.
- The term 'fuel cell' refers to an electrochemical device that converts the chemical energy of a fuel into electrical energy.
PEM Fuel Cell
- The oxidation step in a PEM (Proton Exchange Membrane) Fuel Cell involves the reaction of hydrogen with oxygen at the anode, resulting in the formation of protons and electrons.
