摘　　要：设计并加工了一种小型碳基燃料水蒸气重整制氢装置,该装置为不锈钢材料,采用集成式结构设计,使得加热、气化、重整、分散等多功能部件有机地结合在一起,大大减小了装置的设计尺寸,减小了装置占有空间,降低了装置成本,实现了小型、微型化的目的,便于移动、便携式制氢装置的推广。该反应器装载花状微球Ni/CeO2催化剂,在重整性能测试中甲烷流量为1250mL/min时,水碳比H2O/CH4=2∶1,560℃反应温度下,该反应器表现出了良好的重整制氢性能,重整气中氢气的组成达到70%以上,甲烷的含量降至16%以下,用于高温燃料电池发电的功率计算,满足500W功率设计要求,达到550W以上。实验表明这种重整制氢装置可用于高温燃料电池供氢系统。This research has designed and fabricated a steam reforming for hydrogen production equipment using carbon based fuel. This equipment was made of stainless steel, and applied integrated structure which combined kinds of functional components such as heating, steaming, reforming and dispersion. These structure designs obviously decreased the dimension of this equipment, cut down the cost, achieved the purpose of miniaturization, and reinforced the popularization of portable hydrogen production equipment. This reactor carried flower-like Ni/ Ce20 catalyst, under experiment conditions （the flow rate of CH4 is 1250mL/min, H2O ： CH4 = 2：1, the temperature of reaction is 550℃）, it showed good performance on reforming for hydrogen production. In the reforming gas, the content of hydrogen is more than 70% while CH4 is less than 16%. The power is more than 550W that satisfied the request of design. The experiment result showed the reforming for hydrogen production equipment can be used as the hydrogen source of high temperature fuel cells.
