论文摘要
提出了直接甲醇燃料电池(DMFC)的一维(1-D),等温模型。该模型解释了阳极上多步甲醇氧化反应的动力学。对甲醇的扩散和跨界进行建模,并包括甲醇交叉引起的氧气阴极的混合电势。动力学和扩散参数是通过将模型与25 cm2 dmfc的数据进行比较来估计的。该半分析模型可以迅速解决,以便适合将其纳入实时系统级别DMFC模拟。
A one dimensional (1-D), isothermal model for a direct methanol fuel cell (DMFC) is presented. This model accounts for the kinetics of the multi-step methanol oxidation reaction at the anode. Diffusion and crossover of methanol are modeled and the mixed potential of the oxygen cathode due to methanol crossover is included. Kinetic and diffusional parameters are estimated by comparing the model to data from a 25 cm2 DMFC. This semi-analytical model can be solved rapidly so that it is suitable for inclusion in real-time system level DMFC simulations.
