本研究的目的是制造一个自膨胀燃料电池堆的10个电池与104平方厘米的电池面积加湿与水回收在阴极，并测量和模拟的性能的堆栈。这涉及模拟水和气体反应物在具有水冷却系统的燃料电池组件中的传热和传质的三维模型。堆实验的结果表明，在0.5 A/cm 2的电流密度下，最大功率为250 kW。模拟结果与电堆的实际性能吻合较好。具有蒸汽渗透膜的自增湿电池堆的性能与具有外部增湿器的常规电池堆相当，并且在简化电池堆系统方面显得非常有效。模拟分析表明，对于阳极和阴极处的气体流动方向，平行流动上级交叉流动，并且为了将燃料电池温度保持在100 °C以下，需要一个冷却电池用于两到三个发电电池。© 2002 Wiley Periodicals，Inc.

The objectives of this study were to fabricate a self-humidifying fuel cell stack of 10 cells with 104 cm2 cell areas humidified with water recovered at cathodes, and to measure and simulate the performance of the stack. This involves the simulation of a three-dimensional model of the heat and mass transfer of the water and the gaseous reactants in the fuel cell components with a water-cooling system. The results of the stack experiments indicated a maximum power of 250 kW at a current density of 0.5 A/cm2. The simulation showed good agreement with the actual performance of the stack. The performance of the self-humidifying stack with a vapor-permeating membrane is comparable to a conventional stack with external humidifiers, and it appears very effective in simplifying stack systems. The modeling analysis indicated that for the gas flow directions, at anode and cathode, a parallel flow is superior to a cross flow, and that one cooling cell is necessary for two to three generating cells in order to maintain the fuel cell temperature below 100 °C. © 2002 Wiley Periodicals, Inc.
