That sounds like a free energy device, which is not possible.
Hydrogen has a round trip efficiency of 30% when used in a fuel cell, and closer to 10% when burned in a combustion engine. The energy taken from the alternator will always be much more than the extra energy provided by burning the hydrogen.
Many people have made wild claims about fuel efficiency or free energy devices. If they were true, it would be easy for anyone to replicate the results.










Everyone has to start somewhere. This is a pretty cool proof of concept.
