中文摘要：

本文报道了一种能驱动风扇工作的自呼吸式DMFC小型电堆,电堆主要由燃料储罐、膜电极(MEA)、集流体等组成。文中针对影响该电池性能的主要参数,如电堆的活化过程、甲醇浓度等因素进行了研究。同时,本文还对电堆的恒电流放电时的电流曲线特点以及阴极水的生成规律进行了初步考察和探讨。

英文摘要：

A passive,air-breathing,liquid feed direct methanol fuel cell(DMFC)stack consisting of two unit cells,fuel reservoir,and current collectors has been designed and fabricated to supply the power to an electric fun.Our present investigation primarily focuses on understanding the behavioral patterns of the DMFC stack under the influence of certain operating conditions,such as the activation process,methanol concentration.The operational characteristics and water flooding phenomena of the DMFC stack under consta...
