在Riso国家实验室生产的固体氧化物燃料电池已经通过施加外部电压作为电解电池进行了测试。本文报道了在750 ~ 950°C温度和-0.25 ~-0.50A/cm2电流密度下，这种可逆固体氧化物电池的初始性能和耐久性的结果。对于850°C下的电解操作，全电池具有低至0.27 Ωcm 2的初始面积比电阻。在恒电流长期电解试验期间，观察到电池主要在电解的前100 h期间钝化。在电解测试期间已经被钝化的电池可以通过在燃料电池模式下操作或者甚至在数百小时的测试之后在恒定的电解条件下再次被部分地激活。
Solid oxide fuel cells produced at Riso National Laboratory have been tested as electrolysis cells by applying an external voltage. Results on initial performance and durability of such reversible solid oxide cells at temperatures from 750 to 950°C and current densities from -0.25 A/cm 2 to - 0.50 A/cm 2 are reported. The full cells have an initial area specific resistance as low as 0.27 Ωcm 2 for electrolysis operation at 850°C. During galvanostatic long-term electrolysis tests, the cells were observed to passivate mainly during the first ∼ 100 h of electrolysis. Cells that have been passivated during electrolysis tests can be partly activated again by operation in fuel cell mode or even at constant electrolysis conditions after several hundred hours of testing.
