直接甲醇燃料电池提出了几个有趣的科学和工程问题。有许多工程问题，最终应用有关电池材料，饲料和氧化剂的要求，燃料利用率和回收，扩大规模，等本文着眼于这些问题中的几个从目前的点，典型的，电池性能。使用小规模流动池和大规模池，两者都具有平行通道流动床设计。直接甲醇燃料电池（DMFC）的结构是在固体聚合物电解质（SPE）膜的两侧由两个多孔电催化电极组成：Pt-Ru-C催化剂阳极和Pt-C催化剂阴极。小规模和中等规模（100 cm（2））的细胞流动可视化已被用于设计一个新的大规模的细胞225 cm（2）的有效面积。我们讨论了几个重要的工程因素，包括使用蒸汽和液体进料，热管理，气体管理，甲醇燃料管理，流体力学和质量传输的成功设计的大型DMFC。(C)1999年Elsevier Science S.A.

The direct methanol fuel cell presents several interesting scientific and engineering problems. There are many engineering issues regarding eventual application concerning cell materials, feed and oxidant requirements, fuel utilisation and recovery, scale up, etc. This paper looks at several of these issues starting from the point of current, typical, cell performance. A small-scale flow cell and a large scale cell, both with a parallel channel flow bed design, are used. The structure of the direct methanol fuel cell (DMFC) is a composite of two porous electrocatalytic electrodes; Pt-Ru-C catalyst anode and Pt-C catalyst cathode, on either side of a solid polymer electrolyte (SPE) membrane. Flow visualisation on small scale and intermediate scale (100 cm(2)) cells has been used in the design of a new large-scale cell of 225 cm(2) active area. We discuss several important engineering factors in the successful design of large scale DMFCs including the use of vapour and liquid feeds, thermal management, gas management, methanol fuel management, hydrodynamics and mass transport.
