No, the helium-3 fuses with deuterium (hydrogen-2) to produce helium-4 (the
full-valence, garden-variety helium) and an extra proton.

The advantage to helium-3 fusion is that protons, being charged particles,
can be contained in a magnetic field. Fusion reactions using hydrogen
isotopes such as deuterium and tritium (hydrogen-3) produce neutron, which
can't be contained and radiate harmfully in all directions.
