间接供氢是目前质子交换膜燃料电池理想的氢源供给方式之一。针对间接供氢技术的关键部件层叠式制氢微反应器如何提高单位反应体积内反应速率的技术关键点，围绕单一薄片内微通道阵列结构和薄片层叠结构两个关键影响因素，本项目以微通道之间反应气体速度分布作为切入点，在前期建立单一薄片内光滑微通道流速分布理论模型的基础上，研究单一薄片内微通道阵列结构和催化剂关键参数对微通道传热传质特性的影响机制，建立具有催化剂负载特征的微通道流速分布模型，在此基础上进一步深入研究多场耦合下薄片层叠结构传热传质规律与制氢反应特性耦合作用机制，形成面向层叠式制氢微反应器的多通道多薄片流速分布理论，使我国在微反应器制氢技术以及微通道传热传质理论方面达到国际先进水平。

Indirectly supplying hydrogen is regarded as one of ideal ways of hydrogen sources for the proton exchange membrane fuel cells. The main purpose of this project is to improve the reaction rate per unit reaction volume of laminated-microreactor for hydrogen production based on two key influencing factors, microchannel array structure in a single sheet and laminated-sheet structures. On the basis of the early-established model of velocity distribution among microchannels in a single sheet, the influences of key parameters of microchannel array structure and catalysts on the characteristics of heat and mass transfer in microchannels will be studied in this project. The model of velocity distribution among microchannels with coated catalysts will be established. The relationship among the reaction characteristics of hydrogen production in a laminated-microreactor, heat transfer and mass transfer under multiple fields will be furtherly investigated. The theory formation of velocity distribution among multiple microchannels and sheets for laminated-microreactor will promote the development of hydrogen production in microreactors and the theory of heat and mass transfer in microchannels.
