Management of the operation of a system for producing electric power from hydrogen and hydrogen from electric power

摘要

A system (1) for producing electric power from hydrogen and hydrogen from electric power, comprising: - a reversible electric power -hydrogen conversion stage (2) comprising a fuel cell stack (7) to produce electric power from stored hydrogen and an electrolytic cell stack (9) to produce hydrogen from electric power; - a hydrogen pressure modification stage (3) to modify the pressure of hydrogen supplied to or produced from the reversible electric power -hydrogen conversion stage (2); an electric power management and conditioning stage (4) to condition electric power from/to the reversible electric power -hydrogen conversion stage (2); and a management stage (5) to differentially manage the operation of the reversible electric power- hydrogen conversion stage (2), the hydrogen pressure modification stage (3) and the electric power management and conditioning stage (4) according to whether the system (1) produces electric power from hydrogen or hydrogen from electric power and on a user- set table operation management strategy.
