WORK PACKAGE 4 - HIGH TEMPERATURE ELECTROLYSIS PART
Sustainable hydrogen production as an energy vector for decarbonised world, can be made possible by effective implementation of electrolysis system. Among many electrolysis methods, high temperature electrolysers based on solid oxide cells, with operating range in 750 ºC to 1000 ºC, offer - high combined electrical and heat efficiency, high reaction kinetics (leading to usage of non-noble catalysts) and fuel flexibility advantages.
In addition this system can be used to produce syngas (electrolysis of steam and carbon di oxide). Their half-cell reaction involves, hydrogen evolution on steam side and oxygen evolution on the other side, with the electron movement through the electrode pathway and oxide ion movement along the ceramic membrane pathway.
A process diagram of single cell 10 x 10 cm2 - solid oxide electrolysis system, being developed in Laboratory of Chemical Technology campus, in Ghent Univbersity, Belgium is given on the right side (more updates to follow).
