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 fuel cell system and an operating method of the same. The fuel cell system includes a carbon monoxide adsorbing device that is disposed at an exit of a shift reactor and removes carbon monoxide which is not completely removed in the shift reactor. Therefore, a start-up time of the fuel cell system is remarkably reduced without poisoning catalysts of electrodes of the fuel cell. An overall volume of the fuel cell system can be reduced since the carbon monoxide adsorbing device is only operating during the start-up, and thus the fuel cell system can be economically manufactured and operated. Additionally, the carbon monoxide adsorbent can be regenerated, thereby increasing economic efficiency of the fuel cell system.

Abstract:
A flat panel display is disclosed. In one embodiment, the display includes i) a first substrate including a display area, wherein at least one display element is formed in the display area, ii) a second substrate covering the display area and connected to the first substrate, iii) a sealant formed between the first and second substrates. In one embodiment, the first substrate and the second substrate comprise a first cut surface and a second cut surface, respectively. Further, each of the first cut surface and the second cut surface has a plurality of corners each of which is concave from the perspective of the display area.

Abstract:
A method and system for cleaning an electronic document are provided. The method comprises: identifying at least one sentence in the electronic document; numerically representing features of the sentence to obtain a numeric feature representation associated with the sentence; inputting the numeric feature representation into a machine learning classifier, the machine learning classifier being configured to determine, based on each numeric feature representation, whether the sentence associated with that numeric feature representation is a bad sentence; and removing sentences determined to be bad sentences from the electronic document to create a cleaned document.
Abstract:
A catalytic system for CO removal includes a gold (Au) catalyst and a co-catalyst in contact with an aqueous phase, and a fuel cell system using the same. The catalytic system is relatively very simple compared to a common CO removal system, and can highly efficiently remove CO at low temperature without side reaction. In addition, water contacted in the catalytic system can act as a buffer for the rise and fall of temperature, and thus, can cope with an accidental temperature change. Further, the catalytic system shows a low operation temperature, and thus, can be operated over a broad operation range considering the activity and/or selectivity of the gold catalyst, etc.
