Due to the negative impact of traditional energy resources on the atmosphere, there is a growing shift toward sustainable alternatives. Hydrogen has emerged as a key player as energy vector in reducing greenhouse gas emissions and storing renewable energy. In recent years, producing green hydrogen through water electrolysis with reversible electrochemical devices has become a viable solution. Among hydrogen production methods, protonic ceramic electrolysis cells (PCECs) are gaining attention for their high efficiency, adaptability, and performance at lower operating temperatures (400-700°C). Despite these advantages, challenges remain in optimizing materials and manufacturing methods to improve PCEC performance, scalability and durability. This study focuses on innovative approaches to manufacturing PCEC electrolytes using additive manufacturing (AM) techniques to enhance reliability, precision, and performance.
