甲醇水蒸气催化重整作为聚合物电解质膜燃料电池的一种制氢手段进行了研究。对以前工作的回顾表明，对高压下的操作过程缺乏了解。此外，该过程的早期模型没有考虑一氧化碳的产生速率。建立了CuO/ZnO/Al_2 O_3催化剂上甲醇水蒸气重整反应动力学的半经验模型。该模型能够预测重整器的性能相对于开发集成的重整器-聚合物燃料电池系统中重要的各种参数。给出了一组转化炉温度和CO生成量的计算实例。重整器催化剂的性能对整个燃料电池动力系统的设计的影响进行了讨论。催化剂的选择性，以尽量减少在燃料气体中的CO含量被证明是更关键的比以前认为。
Catalytic steam reforming of methanol has been studied as a means of generating hydrogen for a polymer electrolyte membrane fuel cell. A review of previous work has revealed a lack of understanding of the process for operation at elevated pressures. Also, earlier models of the process do not consider the rate of production of carbon monoxide. A semi-empirical model of the kinetics of the catalytic steam reforming of methanol over CuO/ZnO/Al2O3 catalyst has been developed. This model is able to predict the performance of the reformer with respect to the various parameters important in developing an integrated reformer-polymer fuel cell system. A set of sample calculations of reformer temperature and CO production are given. The impact of the performance of the reformer catalyst on the design of the overall fuel cell power system is discussed. The selectivity of the catalyst to minimize CO content in the fuel gas is shown to be more critical than was previously believed.
