摘要： 对直接甲醇燃料电池(DMFC)的热量管理进行了理论分析。根据DMFC热量管理的要求，设计了一种适用于DMFC堆的新型分形网络冷却通道。计算出了该分形网络通道的最优化结构参数，并定量地分析了冷却水流量和热负荷对DMFC堆的温度分布的影响。计算结果可应用于冷却水最佳流量的选取和电池堆的优化设计。

Abstract:

A theoretical analysis is carried out for the effective heat management of a direct methanol fuel cell. Based on the requirement of heat management, a novel cooling system with fractal network channels is designed for the direct methanol fuel cell stacks. Optimum structural parameters of the fractal network channels are calculated, and the effect of flux of cooling water and heat load on the temperature distribution in the stacks quantitatively analyzed. The results can be applied to determine the optimal flux of cooling water and to optimize the stack design.
