| Abstract Scope |
Protonic Ceramic Electrolysis Cells (PCECs) represent a next-generation approach for hydrogen production, operating efficiently in the intermediate temperature range of 500–600°C. Although gaining momentum in the scientific community, PCECs still face several hurdles:
• Low Faradaic efficiency under certain operating conditions,
• Harsh requirements for the steam electrode (positrode) materials,
• Lack of affordable and scalable production methods.
This presentation will begin with defining the Faradaic efficiency and presenting modeling results that show how PCECs respond to different temperatures and gas conditions. We’ll then explore innovative approaches to improving positrode performance, focusing on composite material strategies. Lastly, tips for producing large-area protonic cells will be shared. |
