This is completely wrong.
A fuel cell takes hydrogen gas and makes electricity by splitting the hydrogen into its constituent electron and protron. The protron passes directly through the membrane, while the electron cannot pass through the membrane and is bypassed into an electrical circuit where the electron flow is captured to create electricity. When both particles pass to opposite side of the membrane, they recombine and mix with oxygen (from air) to create water as a byproduct.
The act of combining the two elementary particles and air HAS NOTHING WHATSOEVER to do with the creation of electricity.
The author does not appear to understand the subject very well.
