直接甲醇燃料电池 (DMFC)功率密度高 ,燃料甲醇价格低廉、储存和携带方便 ,特别适合作为电动车和小型电子设备的电源 ,是目前燃料电池研究领域的一个热点。本文介绍了 40年来DMFC阴极电催化剂的发展历史及现状 ,并针对目前严重影响DMFC性能的“甲醇透过”问题 ,阐述了研制耐甲醇阴极电催化剂的重要性 ,讨论了今后DMFC阴极电催化剂的发展趋势。
Direct methanol fuel cell (DMFC) high power density, low fuel methanol fuel, storage and easy to carry, especially suitable for electric vehicles and small electronic devices, power supply, fuel cell research field is currently a hot spot. In this paper, the development history and current situation of DMFC cathodic electrocatalysts in 40 years are introduced. According to the problem of “methanol permeation” which seriously affects the performance of DMFC, the importance of developing methanol cathodic electrocatalysts is discussed. development trend.
