Study Notes
Fuel Cells
- A device that converts chemical energy into electrical energy through a chemical reaction between fuel (like hydrogen) and an oxidant (like oxygen).
- A continuous source of power as long as fuel is provided, unlike batteries that eventually need to be recharged.
- Generate electricity without combustion, leading to reduced emissions and higher energy efficiency.
- Commonly used fuels in fuel cells include hydrogen, natural gas, methanol, and ethanol.
- The main advantage of using a fuel cell as a power source is its high efficiency, clean energy generation, and continuous operation.
Fuel Cell Types
- There are various types of fuel cells such as Proton Exchange Membrane (PEM) fuel cells, Solid Oxide Fuel Cells (SOFC), and Alkaline Fuel Cells (AFC).
- Each type has its own advantages and disadvantages in terms of operating temperature, efficiency, and material requirements.
- The most common type of fuel cell for automotive applications is the PEM fuel cell.
Fuel Cell Applications
- Fuel cells are used in various applications, including power generation for buildings, transportation (cars, buses, trains), and portable electronics.
- They are also considered as potential power sources for spacecraft and military equipment due to their high energy density and clean energy generation.
