摘要:
The invention relates to a thin micro reforming apparatus used in a fuel cell system. The reforming apparatus includes a substrate having a flow path formed therein, and a fuel inlet portion for introducing fuel to the flow path of the substrate. The fuel inlet portion allows the fuel to flow through a predetermined length of a channel, thereby preheating the fuel. The reforming apparatus also includes an evaporator having a flow path for gasifying liquid fuel, and a reformer for reforming fuel into hydrogen gas via heat absorption reaction. The reforming apparatus further includes a CO remover for removing CO gas contained in the hydrogen gas via heat generation reaction, and a cover for sealing the flow paths of the substrate. The channel of the fuel inlet portion surrounds the evaporator, reformer and CO remover, thereby facilitating insulation at the sides of the reforming apparatus and increasing heat efficiency.

The invention relates to a micro-reformer using a liquid fuel such as methanol and a manufacturing method thereof. The reformer for producing hydrogen gas from the liquid fuel includes a first substrate having a first grooved path and a catalyst layer, and a second substrate having a second grooved path and a catalyst layer, the first and second grooved paths are overlapped on each other forming a micro-channel. The micro-channel has a fuel inlet, a hydrogen outlet, a reforming section, and a carbon monoxide removing section with heating means disposed therein. Although reduced in size, the reformer allows increased hydrogen emission amount due to increased area of the inner path, and is operable with low power due to effective disposition of a heater. This allows manufacturing at low costs and mass-production via semiconductor process.
