About This Chapter
Fuel Cells & Galvanic Cells - Chapter Summary
Chemical cells have a wide variety of uses in modern day technology. Use these lessons to get a firmer grasp on fuel and galvanic cells and how they compare. You can explore basic electrochemical concepts, such as free energy and cell potential. Lessons also explain how batteries work - both rechargeable and single use. As you move deeper into the lessons, you can study chemical reactions and scientific equations that explain cell activity. When you have completed this chapter, you will be able to:
- Discuss electrochemistry in basic terms
- Compare batteries and fuel cells
- Explain how a fuel cell produces energy
- Write half-cell reactions for cathodes and anodes
- Identify the Nernst equation and use it effectively
- Differentiate between voltaic and electrolytic cells
This chapter uses videos and text lessons to quickly and efficiently break complex topics down. The interactive quiz available at the end of each lesson allows you to review what you have just learned and clarify confusing points. You can study these lessons whenever you find the time, using your phone, tablet or computer. The Dashboard in your account page makes it easy to jump back and forth without losing your place.
1. Electrochemistry: Free Energy and Cell Potential Energy
Gibbs Free Energy and cell potential energy measure the spontaneity of electrochemical reactions as energy is converted from chemical to electrical. Learn about galvanic cells, how to measure cell potential energy, and free energy vs. cell potential energy.
2. Types of Voltaic Cells: Batteries vs. Fuel Cells
After completing this lesson, you will be able to explain what a voltaic cell is, and distinguish between two types of voltaic cells: batteries and fuel cells. A short quiz will follow.
3. How Rechargeable Batteries Work
Rechargeable batteries are an innovative solution to allow devices to simply recharge for many uses. Learn the different components, processes, and influencing factors related to rechargeable batteries.
4. What Is a Fuel Cell?
In the desire to stop polluting our atmosphere and find inexpensive energy, fuel cells seem to make a lot of sense. In this lesson, we'll discuss what they are and how they work.
5. Cathode and Anode Half-Cell Reactions
Electrochemical reactions are comprised of two half-reactions, anode electrode & cathode electrode, that are added together to produce the full cell reaction. Learn about electrode half-reactions, corrosion, and how to use half-reaction formulas to calculate cell voltage potential.
6. Nernst Equation: Example & Calculator
In this lesson, you'll find out what the battery in your cell phone has to do with the Nernst equation. Through the use of easy-to-understand explanations, you'll have the chance to decode the equation and see how it works under a set of conditions.
7. The Differences Between Voltaic & Electrolytic Cells
Voltaic cells produce electric energy from chemical reactions, and electrolytic cells convert electric energy to chemical energy. Identify the key similarities and differences between these two cells through examples of their use.
8. Electrolytic Cells
As hinted by their name, electrolytic cells can conduct electricity and perform several functions. Learn about electrolytic cells, including how they work to separate water, and how they compare to voltaic cells.
9. Electrochemical Cells and Electrochemistry
Electrochemical cells are part of electrochemistry. Explore the parts of an electrochemical cell, the definition of an electrochemical cell diagram, the functions of the anode and the cathode, and how to make a homemade battery.
