流道结构和几何尺寸对燃料电池性能影响的实验研究

EFFECTS OF GAS FLOW DISTRIBUTOR STRUCTURES AND GEOMETRIC DIMENSIONS OF THE POLAR PLATES ON THE PERFORMANCE OF A PEM FUEL CELL

流场板是质子交换膜燃料电池重要部件之一。本文对以氢气和氧气作为反应气体的质子交换膜电池的极化曲线进行了实验测定,研究了不同流场板结构、流场板深度和宽度对电池性能的影响．研究发现采用组合流道的电池性能最佳．

Flow field plate is one of the key components in proton exchange membrane fuel cell （PEMFC）. In the present work, the polarization curves were measured under the different operating conditions with hydrogen and oxygen as reactant gases. The effects of gas flow distributor structures and geometric dimensions on the performance of a PEM fuel cell were experimentally studied. The experimental results showed that the combined polar plate PEMFC is the best.
