Abstract: 본 발명은 마이크로 반응기 내부에 형성된 미세 유로에서의 촉매 반응을 수반하는 화학 반응을 일으키기 위하여 미세 유로가 촉매 층에 의한 막힘 현상이 없도록 미세 유로의 내벽에만 효과적으로 촉매 층을 코팅할 수 있는 방법을 제시한다. 본 발명에서는 슬러리 형태의 촉매 코팅액을 이용하여 채우기-건조법(fill and dry coating)을 적용함으로써, 마이크로 반응기의 미세 유로 내벽에만 촉매 층의 코팅이 이루어지도록 하였다. 또한 미세 유로 표면과 촉매 층과의 접착력 향상을 위하여 미세 유로 표면에 실리콘 산화막을 형성하였다. 본 발명의 기본 개념인 채우기-건조법에 따르면, 미세 유로의 크기와 더불어 촉매 슬러리의 점도에 따라 코팅되는 촉매 층의 두께 및 미세 유로의 막힘 현상에 영향을 주므로 이를 적절히 조절하여 최적화된 촉매 층을 갖는 마이크로 반응기를 얻을 수 있다.

Abstract: A method for fabricating a micro-reactor is provided to prevent a catalyst from being coated on unnecessary regions in the micro-reactor fabricating process, simplify the cumbersome fabricating process, effectively form a catalyst layer only on inner walls of microchannels even after reactor bonding, and prevent cracking or exfoliation of the catalyst layer even after the reaction is proceeded. A method for fabricating a micro-reactor comprises: a first step of preparing a substrate having microchannels; a second step of flowing a catalyst coating solution into the microchannels of the substrate to fill the microchannels with the catalyst coating solution; and a third step of drying the substrateto form a catalyst layer on inner walls of the microchannels only by surface tension of a solvent contained in the catalyst coating solution. The first step includes the steps of: (a) forming microchannels on at least one of two substrates to be bonded; and (b) bonding the two substrates. The second step is conducted by flowing the catalyst coating solution into the microchannels by a syringe. The third step of drying the substrate includes the steps of: drying the substrate at room temperature; heat-treating the substrate dried at the room temperature at a temperature higher than the room temperature. The method further comprises the step of forming an oxide layer on the substrate prior to the second step to form easily the catalyst layer on the substrate.

Abstract: A micro reforming reactor for a fuel cell and a method for preparing the same are provided to form a micro tunnel by direct and close contact between a substrate formed with a micro channel and another substrate and form a catalyst layer on an inner wall of the micro tunnel selectively, thereby simplifying the preparing of the micro reforming reactor. A micro reforming reactor for a fuel cell includes a first substrate formed with a micro channel of which a width is 1000mum or less, a second substrate directly and closely contacting the first substrate at the surface formed with the micro channel, a catalyst layer alternatively formed on an inner wall of the micro tunnel, and an adhesive layer formed between the catalyst layer and the inner wall of the micro tunnel.
