A hydrogen production system that achieves highly-efficient hydrogen production even when hydrogen is produced by using the plurality of cell stacks is provided. A hydrogen production system includes a plurality of cell stacks provided within a reaction containment, the cell stacks generating hydrogen by high temperature steam electrolysis by supplying steam to the plurality of cell stacks, a first flow path guiding the steam to each of the cell stacks, a second flow path causing a carrier gas containing air as a main component to flow into the reaction containment, and a flow regulation device provided at an inlet of the steam in each of the cell stacks, the flow regulation device regulating a flow rate of the steam caused to flow into each of the cell stacks to be uniform.

Hydrogen production system and method for producing hydrogen

One embodiment of an electromagnetic flow rate measurement system includes electromagnetic flowmeters arranged at intervals from one another in the peripheral direction of an annular flow passagein which an electric conductive fluid flows. Each of the electromagnetic flowmeters comprises: an excitation member that has magnets arranged at intervals from one another in the outer peripheral surface of the annular flow passage so as to form a magnetic field in the direction perpendicular to the outer peripheral surface of the annular flow passage; and electrodes that are provided between the magnets of the excitation member and between the magnets of the excitation member so as to measure voltage generated when the electric conductive fluid crosses the magnetic field. The polarities of the magnets at the end portions of the closest excitation members of the adjacent electromagnetic flowmeters are opposed to each other.
