galvanic cell
This term refers specifically to a device where the chemical reaction is spontaneous, meaning it generates electricity without an external power source. It is often used interchangeably with "voltaic cell" in introductory chemistry, though some technical contexts distinguish the two based on the nature of the electrodes.
In professional scientific discourse, the term is used to contrast with "electrolytic cells," which require an external electrical current to drive a non-spontaneous chemical reaction. The term is strictly technical and is rarely encountered outside of chemistry, physics, or electrical engineering contexts.
