An electrode catalyst for a fuel cell and a fuel cell including an electrode having the electrode catalyst, include a non-platinum (Pt) catalyst, and a cerium (Ce) metal catalyst, both of which are supported on a carbon-based catalyst support having an improved catalytic activity at a decreased cost. The non-Pt catalyst may be at least one selected from the group consisting of Mn, Pd, Ir, Au, Cu, Co, Ni, Fe, Ru, WC, W, Mo, Se, any alloys thereof, and any mixtures thereof, and the Ce metal catalyst may be a Ce oxide.
Abstract:
A porous plenum spacer is inserted into the plenum of a dual-cooled fuel rod having concentric inner and outer cladding tubes. The porous plenum spacer includes a hollow cylindrical body inserted into the annular space between the inner and outer cladding tubes. The hollow cylindrical body includes a plurality of through-holes formed in an outer circumference thereof or at least one groove formed in one of outer and inner circumferences thereof in a lengthwise direction. Pores formed by the through-holes or the grooves of the hollow cylindrical body of the porous plenum spacer are allowed to secure a space containing fission gas inevitably generated by a nuclear reaction.
Abstract:
A fuel reformer burner in which fuel gas and anode-off-gas (AOG) may be burned and backfire may be prevented during combustion of AOG includes a fuel supply portion, an anode-off-gas (AOG) supply portion; and a combustion air supply portion. The fuel supply portion and the AOG supply portion are arranged inside the combustion air supply portion, which is formed to extend beyond the discharge sides of the fuel supply portion and the AOG supply portion.
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:
Disclosed herein is a guide thimble of a nuclear fuel assembly, which is capable of improving the cooling performance and the stability of a nuclear fuel, preventing a flow split in dual-cooling nuclear fuel rod and guide thimble sub channels for obtaining high combustion degree and high power, and minimizing a neutron absorption section in a reaction degree region. Since the guide thimble having the dual tube type structure is adopted, a flow split in the fuel rod and guide thimble sub channels can be reduced, and the degradation in performance of nuclear fuel due to increase of a neutron absorption section can be prevented. In order for compatibility with an existing control rod, a typical guide tube is used as an inner guide thimble, and an outer guide thimble is provided outside the inner guide thimble. Thus, the guide thimble has the dual tube type structure as a whole, and is coupled to the upper and lower end fittings so that it can prevent a flow unbalance due to the flow split in the fuel rod and guide thimble sub channels.
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 system and method for generating a robot genome. Internal state attribute preferences of internal states and behavior preferences are input by a user, and a set of one or more robot genomes containing initial values of genes is generated. A masking process of each robot genome of the generated robot genome group is performed so attributes are manifested. Robot genomes that underwent the masking process are loaded into a personality engine. A reliability value is calculated from a manifestation result of each robot genome, and reliability values of extracted robot genomes that satisfy a particular user reliability value are determined. Extracted robot genomes are modified when the user reliability value is not satisfied, and a new robot genome group including the modified robot genomes is generated. A robot genome satisfying the user reliability is extracted by iteratively performing the above procedures for the newly generated robot genome group.
Abstract:
A fuel processor having an improved structure to rapidly increase a temperature of a CO removing unit to an operation temperature, and a method of operating the fuel processor, includes a reformer that produces hydrogen gas by reacting a fuel and water; a CO removing unit that removes CO from the hydrogen produced in the reformer. The CO removing unit comprises a CO shift reactor including a first catalyst that catalyzes a reaction between steam and CO and a second catalyst that catalyzes a reaction between oxygen and CO and between hydrogen and oxygen, and a CO remover including a third catalyst that catalyzes a reaction between oxygen and CO; and an air supply unit that supplies air to the CO shift reactor and the CO remover. The use of the fuel processor can greatly reduce a warming up time required to reach a normal operation of the fuel processor since the CO shift reactor can be rapidly heated using a direct reaction between oxygen and CO and between oxygen and hydrogen during an initial start up operation.
