<p>The present invention provides a hydrogen production system which is capable of suppressing the occurrence of a reverse reaction in a hydrogen producing device when electrolysis stops due to switching of the connection configuration of the hydrogen producing device based on fluctuations in renewable energy. The hydrogen production system (100) of the present invention includes a generator (1) which switches from renewable energy to electric energy, a plurality of hydrogen producing devices (2a-2n) connected in series or in parallel for producing hydrogen gas using electric energy obtained from the generator (1), and switching elements (4-6) for switching the connection configuration of the plurality of hydrogen producing devices (2a-2n). The hydrogen production system also includes a voltage applying means (3a-3n, 7) for applying voltage and a control device (8) for controlling the switching elements (4-6) and voltage applying means (3a-3n, 7) when production of hydrogen gas stops in one of the hydrogen producing devices (2a-2n) due to switching of the connection configuration by the switching elements (4-6).</p> |
