Abstract

A hydrogen generating apparatus of the present invention includes a controller (20) configured to, during a stop period, control a material gas feeding device (10) to feed a material gas to a gas passage which is located between the material gas feeding device (10) and a valve (16) to perform a maintaining process for maintaining a pressure in an interior of the gas passage at value which is not smaller than a first threshold which is an atmospheric pressure or larger. When the controller (20) detects there is an abnormality in the maintaining process, the controller (20) controls the material gas feeding device (10) and an ignition device (5A) to feed the material gas with an amount which is larger than an amount in a case where the controller detects there is no abnormality in the maintaining process, during a period which lapses from when the controller detects the abnormality until the ignition device starts an ignition operation in a start-up process.
