Chapter 6: Fuel Cells

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Fuel Cell Vs Galvanic Cell

Fuel Cell
Galvanic Cells
- Galvanic cell type
- Reactants contained within cell
- Reactants supplied to cell
- 60-90% efficiency
- 40-60% effici­ency, up to 85%
- Portable energy
- Continuous source of high electrical currents
 

Advantages Vs Disadv­antages

Advantages
Disadv­antages
- More efficient (direct chemical → electrical energy)
- Expensive use/re­actants
- No COâ‚‚/gr­een­house gases made
- Inverter needed from DC → AC
- Electr­icity made on site
- Hydrogen storage and safety issues
- Many different fuels can be used (most common is hydrogen)
- Hydrogen access issues
