| 摘 要： | 根据熔融碳酸盐燃料电池(MCFC)电堆内部物质能量流动分析得出的温度分布数学模型是一组偏微分方程组.用加权剩余法对顺流型和对流型MCFC偏微分方程组进行求解,用Mathematica软件编写程序计算得到结果.在此基础上比较了上述两种不同流型的优缺点.所得结论对MCFC的流场设计有一定意义.

| Abstract: | The mathematical model of the temperature distribution based on the analysis of material and energy flow in a molten carbonate fuel cell (MCFC) is a set of partial difference equation group. This paper used the MWR method to solve the models of MCFC of co flow and counter flow type, then simulated and computed out the result with Mathematica. It compared the advantages and disadvantages of the two flow types on the basis of the result. The proposed conclusion has some guidance in devising of the flow type of MCFC. |
