Which type of cell can be recharged by passing electric current in the reverse
direction?
Secondary cell
Cells are classified by whether the chemical reaction that produces electricity can be reversed by an external current, and this reversibility is what decides if a cell can be recharged.
A secondary cell uses reversible electrode reactions, so passing current through it in the reverse direction drives the reaction backwards and restores the original active materials.
This means a secondary cell, such as a lead-acid or nickel-based type, can be discharged and recharged many times over its life.
A primary cell relies on reactions that are chemically one-way; once the active materials are consumed it cannot be restored by reverse current.
A dry cell is a common form of primary cell and shares this non-rechargeable limitation.
A fuel cell generates electricity continuously from a supplied fuel and oxidant rather than by storing and reversing a reaction, so it is not recharged in the reverse-current sense either.
Hence, the answer is Secondary cell.
