摘要:
A thin type reforming apparatus used for a fuel cell is provided. In the thin type reforming apparatus, a substrate has a passage formed therein, and a fuel inlet introduces fuel to the passage. An evaporator is disposed within the substrate downstream of the fuel inlet, and includes a bubble remover for imparting a flow resistance to the fuel in a liquid state, removing bubbles and vaporizing the fuel. A reformer has a passage formed downstream of the evaporator, and reforms the fuel to hydrogen gas through a heat absorbing reaction. A CO remover has a passage formed downstream of the reformer and removes CO gas included in the hydrogen gas through a heat radiating reaction. A cover covers an upper portion of the substrate and sealing the passages from an outside.

A fuel cell includes a cell unit and a manifold capable of collecting electric current. The cell unit includes a tube support composed of a conductive material, a unit cell laminated on an outer surface of the tube support, and a current collection layer laminated on an outer surface of the unit cell. The manifold includes an inner tube supplying gas into and electrically connected with the tube support, and an outer tube provided outside the inner tube and electrically connected with the current collection layer. By the provision of a current-collectable manifold, a separate metal form or metal wire for current collection is not required.

A catalyst filling method in a micro channel and a reformer manufactured by the method. The catalyst is filled in the micro channel using water, and unidirectional pressure is applied to the catalyst in the micro channel to fill the micro channel with high density. The catalyst in the micro channel is dried. The method according to the present invention allows uniformly filling the catalyst particles in the micro channel of the reformer with high density, increasing the reactive surface area of the catalyst particles with the fuel, thereby allowing highly efficient reforming effect.

Disclosed is a manifold of a fuel cell, including a conductive support having an upper support member and a lower support member between which two or more anode-supported tubular unit fuel cells each comprising an anode layer, an electrolyte layer and a cathode layer formed in sequential order are disposed and which include an inner connector and an outer connector formed to be tightly fitted into an inner surface and around an outer surface of the unit fuel cells so as to electrically conduct the unit fuel cells, such that the unit fuel cells are alternately connected with the inner connector and the outer connector at an upper end and a lower end thereof thus forming an electrical series circuit. The manifold which is essentially manufactured to supply fuel to a solid oxide fuel cell is used to simply collect current from the fuel cell even without an additional current collector being used, and is configured such that unit fuel cells disposed in the manifold are connected in series.
