Apparatuses for gasifying glycerol using solar energy, system including the apparatuses, and methods of using the apparatuses are provided. The apparatuses may include a concentrated solar dish comprising an opening and a gasifying reactor comprising a chamber. An entrance of the chamber may be aligned to the opening. The apparatuses may also include a thermal insulator disposed on outer surfaces of the concentrated solar dish and the gasifying reactor and a pipe in the thermal insulator. The pipe may be configured to deliver glycerol into the chamber of the gasifying reactor in the form of atomized mist. The glycerol may be delivered to a portion of the chamber adjacent the opening.

A hydrogen-producing device is provided which can start up without receiving an energy supply from the outside. This hydrogen-producing device 1 is provided with an input unit 11 which is connected to a hydrogen source 41, a reformer 12 which produces a hydrogen-containing gas, a hydrogen storage container 13, a fuel battery 15 which generates power using the hydrogen-containing gas, and a control unit 18. The hydrogen storage container 13 is connected to a fuel hydrogen supply path 16 for supplying hydrogen to the fuel battery 15, and to an external supply path 17 which supplies hydrogen to an external load 42. The control unit 18 stores a threshold value of the hydrogen-containing gas necessary for start-up of the fuel battery 15, and controls the amount stored in the hydrogen storage container 13 to be greater than or equal to the amount necessary for start-up of the fuel battery 15. Further, when starting up the hydrogen-producing device, the fuel battery 15 generates power by receiving a supply of the hydrogen-containing gas stored in the hydrogen storage container 13 and supplies power to the reformer 12 from a power supply path 30. The reformer 12 starts up and hydrogen is produced.
