Microreactor systems with functions of catalytic reaction of steam reforming and membranes for Co removal were developed for use in fuel cell systems. The following results were newly obtained in this study.(1) Techniques for fabricating microchannels and modifying channel walls were developed, using various substrates which were resistant to elevated temperature and corrosive chemicals.(2) Techniques for coating the microchannels with metal catalysts were developed.(3) A system which enabled to select proper catalysts efficiently was developed by combining the microchannels catalytic reactors and a quadropole mass spectrometer.(4) A microchannel catalytic reactor was systemized with a miniaturized heater and thin film temperature sensors. Thus a thermally self-supporting microreactor was prepared.(5) A liquid evaporator was developed by combining a pump and a microheater on a silicon substrate. The pump was prepared using three thermally resistant piezoelements and showed a capacity enough for feeding methanol to miniaturized fuel cells.(6) Steam reforming of methanol produces CO, which is a severe catalyst poison, at a high concentration. In order to decrease CO concentration to a level of 10 ppm, temperature resistant inorganic membranes (zeolite and palladium) were developed. The zeolite membranes functioned as a high performance CO oxidation reactor, and the palladium membrane showed a very high H_2/CO selectivity.

开发了具有蒸汽重整催化反应和除钴膜功能的微反应器系统，用于燃料电池系统。本研究取得了以下新成果：（1）开发了使用各种耐高温和耐腐蚀性化学品的基材制造微通道和修饰通道壁的技术。（2）开发了用金属催化剂涂覆微通道的技术(3)通过将微通道催化反应器和四极杆质谱仪相结合，开发了一种能够有效选择合适催化剂的系统。(4)将微通道催化反应器系统化小型加热器和薄膜温度传感器。这样就制备出了热自支撑微反应器。(5)在硅基片上结合泵和微加热器研制了液体蒸发器。该泵采用三个耐热压电元件制成，具有足够的能力将甲醇输送到小型燃料电池中。(6)甲醇的蒸汽重整产生高浓度的CO，这是一种严重的催化剂毒物。为了将 CO 浓度降低至 10 ppm，开发了耐温无机膜（沸石和钯）。沸石膜充当高性能CO氧化反应器，钯膜表现出非常高的H_2/CO选择性。
