实际应用时燃料电池的运行条件会随时间不断地变化,因此是一个非稳态过程.本文研究了在不同的加湿条件以及反应气流量下电池的启动特性.结果表明:随着气体流量的增大,电池启动速度加快;对电池加湿有利于提高电池的启动性能.
As the operating condition often changes with time,the fuel cell experiences an unsteady process during its practical application.The start-up characteristics of fuel cell in different humidifier temperature and gases flux are studied in this paper.The result shows that the gases flux has an important effect on the start-up of fuel cell.Besides,it is also helpful for the start-up of fuel cell to humidify the reactive gases.
