Quenching the Cold Fusion Reaction

The following methods have been used to quench light hydrogen cold fusion reactions:

• Ceasing the generation of phonons or EM radiation that was used to start the reaction.
• Lowering the temperature.
• separating the reactants.
• Adding deuterium.
• Adding helium.

Since the reaction generates helium, the reaction will ultimately be quenched unless the helium buildup is removed in some way.
