HADES

The overall objective of the HADES project is to develop a single proton ceramic reactor operated at intermediate temperature (500 °C < T < 700 °C) integrating the NH₃ decomposition and H₂ purification / compression steps. The investigation of the decomposition mechanisms will feed the modelling activities, performed at cell and stack level, and help to choose non-critical raw catalysts. The developed models will provide guidance to the reactor development by optimizing the two cell architectures (Metal- and Ceramic-Supported Cells) and select optimized operation parameters, to increase the technology efficiency. Market (TechnicoEconomic Analysis and regulation), social and environment (Life Cycle Assessment and safety) analysis will be performed to challenge the competitivity versus industrially applied catalytic NH₃ crackers. The HADES results will be disseminated and exploited through appropriate communication plan and exploitation roadmap.

• Project coordination 
• Development of proton ceramic electrolysis cells (PCEC) tailor made for NH₃ cracking. Manufacturing reference and innovative cells including development of specific NH₃ and H₂ electrodes and infiltration of specific catalysts into cell structure. 
• Characterization of PCEC materials / cells by X-ray diffractometry (XRD), microstructural analysis (SEM) for cell, electrochemical and electrocatalytic measurements for cell performance. 
• Life Cycle Assessment (LCA) of the HADES system for evaluating its environmental performance.
