Lead-acid batteries release hydrogen when discharged
BatteryStuff Articles | The Lead Acid Battery Explained
The hydrogen reacts with the lead sulfate to form sulfuric acid and lead, and when most of the sulfate is gone, hydrogen rises from the negative plates. The oxygen in the water reacts with the lead sulfate on the positive plates to turn them once again into lead dioxide, and oxygen bubbles rise from the positive plates when the reaction is …
How Lead-Acid Batteries Work
When the battery is discharged, the sulfuric acid reacts with the lead to create lead sulfate and hydrogen ions. This releases electrons, which flow through an …

Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to …
Lead acid batteries
Lead acid batteries can cause serious injury if not handled correctly. They are capable of delivering an electric charge at a very high rate. Gases released when batteries are charging – hydrogen (very flammable and easily ignited) and oxygen (supports combustion) – can result in an explosion.
