Abstract
When the product gas producing operation is stopped, a stand-by operation is executed in which a product gas filling up a reforming processing unit is circulated, in a state in which an adsorbent of adsorption towers is maintained in a state in which adsorption target components are desorbed, and the heating of a reformer by a heating burner is maintained, and when the stand-by operation is stopped and the product gas producing operation is started, initial operation processing is executed in which immediately after the start, a source gas and steam are supplied to the reformer to produce a reformed gas, and the reformed gas from the reforming processing unit supplied to the adsorption towers to produce the product gas, and then the product gas producing operation in which the product gas is collected in a product gas tank is executed.
