Hydrogen flows into the fuel cell and is stripped of its single electron. That electron is then used for power. The hydrogen ion, meanwhile, flows through the membrane and attaches itself to incoming airborne oxygen (O2). They hydrogen and oxygen combine to create water (H2O) and are then released out of the fuel cell.
