Abstract:
A fuel processor that extracts, from a fuel source, hydrogen gas used for an electricity generation reaction. The fuel processor includes a reformer that generates hydrogen gas by reacting a fuel source with water, a burner that heats the reformer to an appropriate temperature for a hydrogen generation reaction, a CO remover that removes CO generated during the hydrogen generation reaction in the reformer, and a heat exchanger for cooling the CO remover.
Abstract:
A fuel reformer burner for a polymer electrolyte membrane fuel cell (PEMFC) system includes a first tube through which a fuel for a fuel reformer is supplied and a second tube through which anode-off gas (AOG) is supplied from a fuel cell stack. The second tube is not connected to the first tube, and an inlet line through which an air is supplied is connected to the first tube.
Abstract:
A fuel cell system including a fuel processor, and a method of operating the fuel cell system, the fuel cell system includes: a reformer that reforms a hydrocarbon group fuel source into a reformed gas; a burner that heats the reformer; a CO remover unit that removes CO from a reformed gas generated by the reformer; a stack to generate electricity using the reformed gas; a first burner fuel supply line to supply the hydrocarbon group fuel source to the burner; and a second burner fuel supply line to supply the reformed gas from the CO remover unit to the burner.
Abstract:
A hydrocarbon reforming catalyst, a method of preparing the hydrocarbon reforming catalyst, and a fuel cell including the hydrocarbon reforming catalyst. The hydrocarbon reforming catalyst includes a nickel active catalyst layer loaded on an oxide carrier, and a metal oxide.
Abstract:
A porous oxide catalyst includes porous oxide, and an oxygen vacancy-inducing metal which induces an oxygen vacancy in a lattice structure of a porous metal oxide.
Abstract:
A mesoporous oxide-catalyst complex including: a mesoporous metal oxide; and a catalyst metal supported on the mesoporous metal oxide, wherein the catalyst on the mesoporous metal oxide has a degree of dispersion of about 30 to about 90 percent.
Abstract:
A fuel reformer, includes: a reformer burner, which generates a flame in a reforming pipe disposed to surround at least the flame of the reformer burner, the reforming pipe being filled with a reforming catalyst and having corrugated portions on a surface facing the reformer burner and a bottom surface of the reforming pipe disposed adjacent to the flame in which a flame blocking member is disposed between the flame of the reformer burner and the reforming pipe to isolate the flame of the reformer burner from the reforming pipe.
Abstract:
A method of generating hydrogen, the method including: reducing carbon dioxide to generate carbon monoxide and oxygen; separating the oxygen from the carbon monoxide; generating carbon dioxide and hydrogen by a water-gas shift reaction between water and the carbon monoxide remaining after the separating the oxygen from the carbon monoxide; and separating the generated carbon dioxide and hydrogen.
