Question
In what way fuel cell differs from ordinary galvanic cells ?
✓
Answer
Fuel cell is a modified galvanic cell in which the thermal energy of combustion reactions is directly converted into electrical energy.
In the fuel cell, the reactants are not placed within the cell like ordinary galvanic cells, but they are continuously supplied to the electrodes from outside reservoir.
They cannot be recharged unlike ordinary galvanic cell.
