? ? ?Although I raised the issue of improving the performance of the electrolyzer under fluctuating power supply, I was actually vague about the effect that fluctuating power supply has on the electrolyzer. Because my foundation in electrochemistry is not very solid, this is a big mountain in front of me.

? ? ?Second, I recently vaguely mastered some experimental methods, such as electron microscopy scanning method, but also familiar with some criteria, such as electrochemical impedance spectroscopy, polarization curve, but for the specific how to use these analysis results, I am still not clear.

? ? ?I also learned about the factors that can regulate the performance of the electrolyzer, such as operating temperature, back pressure, inlet gas humidity, cathode gas type, electrolyte content in the catalyst, electrode hydrophobicity, presence of microporous layer, etc.
