Answer

Galvanic cells and fuel cells operate on different principles of energy transformation.

Galvanic Cells: These cells convert chemical energy into electrical energy through spontaneous reactions. Essentially, they generate electricity actively as the chemical reactions occur.
Fuel Cells: In contrast, fuel cells involve the conversion of chemical energy into electrical energy through electrochemical reactions that require a continuous supply of reactants, such as hydrogen and oxygen.

Therefore, while both types of cells ultimately provide electrical energy, the processes and energy transformations involved greatly differ.
