A fuel cell is a typical galvanic cell that is based on a reaction between:
- A
Hydrogen and copper
- B
Methane and oxygen
- C
Hydrogen and oxygen
- D
Nitrogen and oxygen
- E
Hydrogen and zinc
Hydrogen and oxygen: This is the reaction in a hydrogen fuel cell, where hydrogen (H₂) reacts with oxygen (O₂) to produce electricity, water, and heat.
Hydrogen and copper: This combination is not a typical galvanic cell. Copper is not involved in the redox reaction in a hydrogen-based fuel cell.
Methane and oxygen: This is not a typical fuel cell reaction; methane is used in combustion engines, not standard fuel cells.
A fuel cell generates electricity by combining hydrogen and oxygen, producing water as a byproduct.
Nitrogen and oxygen: This combination does not typically occur in a galvanic or fuel cell. Nitrogen is inert and does not participate in the redox reactions.
Hydrogen and zinc: This is not the reaction in a fuel cell; zinc is part of a dry cell battery, not a fuel cell.
