在不同的燃料电池技术，直接甲醇燃料电池（DMFC）提出了一些有趣的科学和工程问题，如饲料和氧化剂的要求，燃料利用率和回收，放大等，有许多过程系统工程（PSE）的问题，仍然没有解决。其中值得注意的是DMFC的结构和设计参数的建模和优化。本文讨论的PSE相关的挑战包括甲醇和水的交叉，反应的低动力学速率，热和水的管理，燃料管理系统，流体力学研究和质量传输。本文还提出了几个重要的工程因素，成功的堆叠设计的DMFC的便携式应用。
Among the different fuel cell technologies, the direct methanol fuel cell (DMFC) presents several interesting scientific and engineering problems such as feed and oxidant requirements, fuel utilization and recovery, scale-up, etc. There are many Process System Engineering (PSE) issues that remain unsolved. Notable among these are the structure of the DMFC and the modeling and optimization of design parameters. The PSE-related challenges discussed in this paper include the methanol and water crossover, the low kinetics rates of the reaction, heat and water management, the fuel management system, hydrodynamics studies and mass transport. Also presented in this paper are several important engineering factors for the successful stacking design of DMFCs for portable applications.
