Fuel Cells All Presentation
| Introduction to Fuel Cells | ||
|---|---|---|
| Fuel cells are devices that convert chemical energy into electrical energy. They are highly efficient and produce electricity without combustion. Fuel cells have various applications, including transportation, power generation, and portable electronics. | ||
| 1 | ||
| How Fuel Cells Work | ||
|---|---|---|
| Fuel cells work by passing hydrogen or other fuels through an anode and oxygen through a cathode. The fuel reacts with the anode catalyst, producing electrons and hydrogen ions. The hydrogen ions travel through an electrolyte and combine with oxygen and electrons at the cathode, generating water and releasing electrical energy. | ||

| Types of Fuel Cells | ||
|---|---|---|
| Proton Exchange Membrane (PEM) Fuel Cells: Use a polymer membrane as an electrolyte and operate at low temperatures. Solid Oxide Fuel Cells (SOFC): Operate at high temperatures and use a solid ceramic electrolyte. Molten Carbonate Fuel Cells (MCFC): Use a molten carbonate electrolyte and operate at high temperatures. | ||

| Advantages of Fuel Cells | ||
|---|---|---|
| High efficiency: Fuel cells can reach efficiencies of up to 60%, compared to 20-30% for combustion-based power sources. Low emissions: Fuel cells produce minimal greenhouse gas emissions and no pollutants if hydrogen is used as fuel. Versatility: Fuel cells can be used in various sizes and applications, from small portable devices to large-scale power plants. |  | |
