Hydrogen redox electric power and hydrogen energy generators

•We have developed the electrostatic induction potential superposed bipolar water electrolyzer.•The electrolyzer is combined with a fuel cell to form an energy cycle for electric power and hydrogen energy generations.•The power efficiency has been defined as the ratio of the power extracted from the generator to that produced by the fuel cell.•We aim at 70% of the power efficiency with this hydrogen energy cycle.

An electrostatic-induction potential-superposed hydrogen electrolytic cell for the synthesis of stoichiometric H2–O2 fuel for fuel cells has been developed for use of the hydrogen energy cycle to produce electric power. This hydrogen electrolytic system works on a mechanism, where the power used is theoretically 17% of the total electrical energy required, while the remaining 83% is provided as electrostatic energy. A combined cycle of H2–O2 fuel cell and this type of electrolyser is introduced to achieve the highest energy efficiency for a fuel cell and full sustainability for the fuel. Part of the power delivered by the fuel cell is returned to the electrolyser, while the remaining represents the net power output. According to theoretical calculations, the net power output can exceed 70% of that delivered by the H2–O2 fuel cell, without violating the laws of thermodynamics.
