【摘要】 以解决小功率燃料电池氢源问题为目的,研制了集原料预热、甲醇水蒸气重整(MSR)、催化燃烧、水汽变换(WGS)于一体的自热式重整制氢反应器。通过条件实验考察了操作温度、甲醇气体空速、水醇比(W/M)等操作条件对重整反应的影响,并在苛刻条件下进行了稳定性研究。实验证明,反应器最大净产氢量可达90 L/h,可为百瓦级质子交换膜燃料电池提供氢源。更多还原

【Abstract】 A compact reactor with coupled reactant preheating,methanol steam reforming(MSR),catalytic combustion and water gas shift(WGS) was fabricated to supply hydrogen for PEMFC.The effects of reaction temperature,methanol gas space velocity(GSV) and ratio of water to methanol on reforming reaction were investigated,and the stability of the mini-reformer was also studied under various operation conditions.The yield of hydrogen reached 90L/hr,able to provide hydrogen for 100W PEMFC.更多还原
