SUMMARY Toward achieving a breakthrough in self‐sustaining electric power generation systems consisting of a hydrogen energy cycle, we demonstrate an electrostatic induction potential superposed hydrogen electrolyzer to produce stoichiometric H2 ‐O2fuel for fuel cells. This electrolytic system operates by a mechanism in which the total power requirement is given by the product of the electrolytic current and the additional voltage over the decomposition voltage. In order to achieve the highest energy efficiency for the fuel cell and full sustainability for the fuel, a combined cycle of an H2 ‐O2fuel cell and this type of electrolyzer is introduced. Part of the power delivered by the fuel cell is returned to the electrolyzer, and the remainder represents the net power output. According to theoretical calculations, the net power output exceeds 70% of that delivered by the H2 ‐O2fuel cell, without violating the laws of thermodynamics.
