Fuels Cells Presentation
| Introduction to Fuel Cells | ||
|---|---|---|
| Fuel cells are electrochemical devices that convert chemical energy from a fuel into electrical energy. They are highly efficient and produce minimal greenhouse gas emissions. Fuel cells have a wide range of applications, including transportation, stationary power generation, and portable devices. |  | |

| How Fuel Cells Work | ||
|---|---|---|
| Fuel cells consist of an anode, cathode, and electrolyte. Hydrogen fuel is supplied to the anode, while oxygen or air is supplied to the cathode. The fuel undergoes oxidation at the anode, releasing electrons that travel through an external circuit, producing electricity. | ||

| Types of Fuel Cells | ||
|---|---|---|
| Proton Exchange Membrane Fuel Cells (PEMFCs) are commonly used in vehicles and portable applications. Solid Oxide Fuel Cells (SOFCs) operate at high temperatures and are suitable for stationary power generation. Molten Carbonate Fuel Cells (MCFCs) and Phosphoric Acid Fuel Cells (PAFCs) are used in large-scale stationary applications. |  | |
