This work focused on the intermittent characteristics of renewable energy and studied the dynamic response characteristics of seawater/CO co-electrolysis on solid oxide cell stacks to produce syngas under strong fluctuation electricity conditions. The results showed that when using a strong fluctuating current density of 58.2–658.1 mA/cm to simulate wind turbines, the power variation of the solid oxide cell stack was almost in line with the simulated wind turbine power variation curve. The theoretical conversion rate of solid oxide cell stack electrolysis products is linearly related to the current density. The measured HO+CO conversion rate is similar to the theoretical value, and the current variation hardly changes the H/CO ratio in the exhaust gas. Therefore, solid oxide electrolysis cell stacks have strong adaptability to fluctuating electricity.

强波动电流下海水/CO2共电解固体氧化物电池堆动态响应特性

该工作针对可再生能源的间歇特性，研究强波动电条件下海水/CO在固体氧化物电池堆上共电解生产合成气的动态响应特性。结果表明，采用58.2~658.1 mA/cm的强脉动电流密度模拟风力发电机时，固体氧化物电池堆的功率变化与模拟风力发电机功率变化曲线基本一致。固体氧化物电池堆电解产物的理论转化率与电流密度线性相关。实测H2O+CO转化率与理论值相近，电流变化几乎不改变废气中的H/CO比。因此，固体氧化物电解槽电堆对波动电力具有很强的适应性。
