摘要
介绍了世界上离子(质子)交换膜燃料电池的最新进展.目前,已商品化的单体电池有效工作面积780cm^2,铂催化剂载量1～4mg/cm^2,工作温度80℃,采用纯氢和纯氧为燃料和氧化剂,工作压力为1.03×10~5～4.48×10~5Pa,工作电流密度为500mA/cm^2时,电池工作电压可达0.7V,工作寿命可达10000～20000h.这种电池在潜艇、飞船及电动汽车等领域有良好的应用前景.
Recent advance in REM fuel cell in the world is described in this paper. To date,the main performance of a commercial PEM fuel cell is:effective surface area 780cm2,Ptcatalyst loading 1 - 4mg/cm2, working temperature 80C ,pure H2 as fuel,pure O2 as oxidiz-er, working pressure 1. 03 X 106- 4. 48 X 106Pa, working current density 500mA/cm2, working voltage 0. 7V(maximum load),mid operating life 10,000-20,000h. Such cells show promising applications in submarine,space mission,electric vehicles and so forth.
