AI Technical Summary
Existing anion exchange membrane electrolysis technology for hydrogen production suffers from long activation times, easy damage to membrane electrodes, and a lack of effective termination criteria, resulting in high energy consumption, low efficiency, poor batch consistency, and difficulty in achieving rapid start-up and large-scale production.
A stepped cyclic voltage boosting strategy is adopted, which uses the current change rate as the termination criterion to gradually increase the voltage and stop activation when the current change rate is less than a preset threshold, thus avoiding electrochemical shock and mechanical stress and achieving rapid, mild and controllable activation of the membrane electrode.
It significantly shortens activation time, improves activation consistency and efficiency, protects the integrity of the membrane electrode structure, reduces energy consumption, and is suitable for standardized and large-scale production.
