Keep adding plates and removing the oxidized plates. The hydrogen produced from these scams are not entirely from electrolysis as that would never produce enough hydrogen to even replace the energy used in electrolysis but also from the oxidation of metals, in effect using metal as a fuel, this metal may not even be directly in the cell but oxidized externally with the electron flow throughout the car.

Basically, for onboard hydrogen generation to work, you need another source of fuel although that source may not be immediately evident to the laymen hence many people are easily lead to believe that the concept worked when in fact there are other reactions occurring. This makes the concept perfect for swindling money from people especially since most people know about electrolysis of water to make hydrogen and oxygen as it’s a common physics demonstration in grade school but few people are aware of the actual amount of energy involved in electrolysis versus how much can be recovered by using hydrogen as a fuel. Add to this that auto manufacturers have occasionally toyed with the idea of a hydrogen car as another designed obsolescence marketing vector and the concept receives an aura of possibility in the minds of the uninformed.

So when you refill your "water" car, replace all the oxidized metal while you’re at it and add some gasoline then pat your back for being so easily fooled.
