How cells make voltage

Comparison of a simple chemical cell and a hydrogen-oxygen fuel cell showing electrodes, electrolyte, external circuit, reactant supply, and water product A chemical cell uses a chemical reaction to produce a voltage, or potential difference, between two electrodes. That voltage pushes charge around the external circuit, so chemical energy is transferred into electrical energy.
