摘　　要：电解质管理是熔融碳酸盐燃料电池（MCFC）的核心技术之一。本文针对MCFC中电解质管理问题,提出了隔膜焙烧的首次启动升温策略,即采用热压法制备电解质膜片,在电池组装之前对电解质膜片进行预处理,将电解质膜片置于马弗炉中在260℃下恒温处理5h,在隔膜焙烧的重要阶段100~450℃区间,将其升温速率控制在0.5℃/min。采用该策略制备的电解质膜片组装了225cm2 MCFC单电池,其性能测试结果表明,使用纯氢燃料时,电池性能良好,最大输出功率密度可达85.2mW/cm2。Electrolyte management is one of the key technologies in molten carbonate fuel cell（MCFC）.To solve the electrolyte management problem,this paper proposed the temperature rise strategy during the first startup of diaphragm roasting,namely using hot-pressing method to prepare the electrolyte film and pretreat the electrolyte film before the unit cell was assembled and tested.The electrolyte film was heated at 260 ℃in muffle furnace for 5hours.Within temperature range from 100 ℃ to 450 ℃,the heating rate was kept at 0.5 ℃/min.An MCFC unit cell with area of 225cm2 was assembled employing the electrolyte film prepared by the above method,the performance test results show that,the electrolyte film unit cell had good performance if using the pure hydrogen as the fuel,the maximum output power density reached 85.2mW/cm2 at current density of 120mA/cm2.
