摘　　要：分析了气体扩散电极在燃料电池发展中的重要性。利用小孔扩散规律中液体通过气孔的蒸腾与气体通过多孔电极参与电化学反应中相似之处,提出按照植物叶片上的小孔扩散规则来设计气体扩散电极的结构;通过简单的对比实验证实该研究思路的正确性,并设计了可行的研究方法。该研究方向的提出有利于多角度全面开展对气体扩散电极的研究,并促进生物学与物理化学渗流学科的交叉。The importance of the gas diffusion electrode in fuel cell development was anatyzeu ing to the resemblance of the liquid rising from gas pore in small pore diffusion law and gas taking part in the electrochemical reaction through porous electrode in fuel cells, we proposed the structure of the porous electrode could be designed as the pore diffusion rule of the plant lamina. A simple contrast experiment was made to approve the correctness of the research idea and feasible research method was designed. The idea helped to develop the comprehensive research of the gas diffusion electrode, also accelerate the crossover of the biology and the physical chemistry fluid mechanics in porous medium.
