Can CO₂ contamination negatively affect the lifetime of the electrolyser?

CO₂ contamination in the air is not a problem for the electrolyser, as the system design avoids potential interaction with the surrounding air. However, CO₂ in the electrolyte (e.g. by refilling with carbonized water reduces the pH value and requires

CO₂ contamination in the air is not a problem for the electrolyser, as the system design avoids potential interaction with the surrounding air. However, CO₂ in the electrolyte (e.g. by refilling with carbonized water reduces the pH value and requires a more frequent electrolyte exchange. When maintained regularly (exchanging the electrolyte), this is reversible and does not contribute to explicit degradation of the electrochemical system.
