| 摘 要： | 研制了管式SOFC试验电池系统，分别以H2和CH4为燃料，空气为氧化剂气体，对管状SOFC在500～950℃范围内的电性能进行研究．考察了温度对电池内阻、输出电流和输出电压的影响．结果表明，当电池工作温度升至950℃时，分别以H2和CH4为燃料，电池开路电压分别为0．98V和1．05V；最大输出电流密度达到19．6mA／cm2和16．4mA／cm2，最大输出功率达到30．0mW和24.4mW经过145h连续试验运行，试验电池性能没有出现任何退化迹象。

| Abstract: | A trial tubular SOFC system was fabricated. The electrical performance of this SOFC was evaluated at temperatures of 500 to 950℃. H2 and CH4 were used as the fuels and air as the oxidant gas. The internal resistance, output current and output power of this SOFC were measured. When H2 and CH4 were imported into the SOFC system at 950℃, the open circuit voltages were 0.98V and 1.05V, maximum output current densities were 19.6mA/cm2 and 16.4mA/cm2, the maximum output power was 30.0mW and 24.4mW, respectively. The endurance test was conducted over 145h, but this SOFC system showed no significant degradation. |
