He was a member of the President's Board of the Italian Physical Society.
From 1992 he had been working on cold fusion with nickel-hydrogen reactors. From 2007 until his death, Focardi collaborated with inventor Andrea Rossi on the development of the Energy Catalyzer (E-Cat).

In the early 90s Sergio Focardi, together with physicists Roberto Habel and Francesco Piantelli, started to develop a nickel-hydrogen exothermal reactor. The results of their research were presented in 1994, and published on the peer-reviewed scientific journal Il Nuovo Cimento A.
