Abstract
The hydrogen production apparatus includes: a rectifier supplied with first electrical power from outside, and that outputs direct-current second electrical power; an electrolyzer supplied with the second electrical power and that carries out electrolysis of an alkaline aqueous solution; a pure water tank that retains a pure water; a pure water pipe connected between the pure water tank and an electrolyzer, allowing the pure water to be distributed from the pure water tank to the electrolyzer; an inert gas cylinder that contains an inert gas; and a first valve connected between the inert gas cylinder and the pure water pipe, is the first valve being closed when the first electrical power is supplied, and being open when the first electrical power is not supplied. The inert gas is introduced into the pure water pipe by opening the first valve.
