摘　　要：微流体燃料电池其阳极侧燃料传质的控制技术直接决定了电池的整体性能。以强化燃料传质的微射流方法作为研究对象,建立空气自流动微流体燃料电池的三维数学模型,对微射流的物理形状与燃料传输和微电池性能的关系进行分析。结果表明,将射流孔设计在中下部位能够强化燃料传输效果;增加射流孔数量能扩大微射流的作用区域,但会降低射流速度,此时燃料传输与电池性能呈现先提高后降低的趋势;扩大射流孔面积会降低射流速度,在一定程度上降低微电池性能。The control technology of fuel mass transfer on anode side of microfluidic fuel cell directly determines the overall performance of the cell.The micro jet method was used to enhance fuel mass transfer.The three-dimensional mathematical model of the air self flowing microfluidic fuel cell was established.The relationship between the physical shape of the micro jet and the fuel transmission and the performance of the micro cell was analyzed.The results show that the design of jet hole in the middle and lower part can enhance the fuel transfer effect.Increasing the number of jet holes can enlarge the effect area of micro jet,but it will reduce the jet velocity.At this time,the fuel transmission and battery performance will be improved and then decreased.Expanding the area of the jet hole will reduce the jet velocity and reduce the performance of the micro cell to a certain extent.
