      abstract     = {Solid oxide electrolysis cells (SOECs) are promising
                      electrochemical conversion devices for Power-to-Gas
                      technologies but face degradation issues with conventional
                      nickel-based fuel electrodes (e.g. Ni-YSZ or Ni-GDC) at high
                      current densities. This research investigates the potential
                      of using praseodymium doped ceria (PDC) as a nickel-free
                      alternative. For this purpose, three different materials
                      were tested: $5\%$ lanthanum and $5\%$ praseodymium doped
                      ceria (LPDC), $10\%$ praseodymium doped ceria (PDC10), and
                      $30\%$ praseodymium doped ceria (PDC30). In an
                      electrochemical performance evaluation under steam
                      electrolysis conditions at 900°C, PDC10 outperformed both
                      LPDC (-1.37 A/cm²) and PDC30 (-1.1 A/cm²), achieving a
                      current density of -1.5 A/cm² at 1.5 V. Future work will
                      include structural and electrochemical analysis of all three
                      samples to evaluate their physico-chemical behavior at a
                      fundamental level. In conclusion, these findings suggest
                      that praseodymium-doped ceria could be a promising candidate
                      for efficient and durable fuel electrode materials in
                      SOECs.},
