Abstract: An ejector and a refrigeration cycle apparatus having an ejector are provided. The ejector may include an ejector body having an accommodation space therein, a suction portion through which a high pressure refrigerant and a low pressure refrigerant may be suctioned into the accommodation space, and a mixing portion configured to mix the high pressure refrigerant with the low pressure refrigerant; a nozzle provided in the ejector body, having a nozzle neck and an expansion portion, and configured to inject the high pressure refrigerant into the mixing portion; a first needle moveably provided at the expansion portion, and configured to control a flow sectional area of the expansion portion; a second needle moveably provided at the nozzle neck, and configured to control a flow sectional area of the nozzle neck; a first needle drive configured to drive the first needle; and a second needle drive configured to drive the second needle. With such a configuration, the flow sectional area of the nozzle neck and the flow sectional area of the expansion portion may be independently controlled in correspondence to a drive condition.

Abstract: A fuel reforming device includes a combustion part including a burner; an exhaust part configured to circulate an exhaust gas that is generated from the combustion part; and a reactor that is configured to generate hydrogen from a raw material by absorbing heat from the exhaust gas circulating in the exhaust part. The reactor includes a heat storage member that is configured to absorb the heat from the exhaust gas during operation of the combustion part, store the absorbed heat, and provide the absorbed heat to the reactor.

Abstract: A fuel cell has a stack that includes a fuel electrode and air electrode on opposite sides of an electrolyte membrane. The fuel electrode includes first and second fuel ports communicative via a fuel flow path, and the air electrode includes first and second air ports communicative via an air flow path. The fuel cell also includes first and second fuel feeders communicative with the first and second fuel ports, and first and second air feeders communicative with the first and second air ports. The fuel cell also includes a fuel switching unit between the first and second fuel feeders that switches a fuel supply direction between the first and second fuel feeders. The fuel cell further includes an air switching unit between the first and second air feeders that switches an air supply direction between the first and second air feeders.
