Periodic Reporting for period 2 - OxiGEN (Next-generation Solid Oxide Fuel Cell stack and hot box solution for small stationary applications)
Berichtszeitraum: 2019-07-01 bis 2021-06-30
Three exploitation paths have been identified for Key Exploitable Results (Hot box specifications, in particular regarding size and operation mode (ENGIE), Hot box for Saint-Gobain stack (Saint-Gobain) and Novel electrolyte composition with improved conductivity and stability than YSZ (joint result SINTEF + Saint-Gobain) through commercialisation, new research project or Licensing.
The target of 30% improvement of electrolyte conductivity was overpassed with an intrinsic conductivity 350% higher than the reference.
The total cost of ownership for the final device has been estimated but are based on industrial assumptions, in parallel we have developed a total cost of ownership model for many European countries with and without incentives.
During the project, we couldn't get to a micro-CHP hot box tested in a system as it was initially planned because we discovered unexpected challenges during the implementation of the project.
We made a lot of good progress in several parts of the project:
· A solution for stable ceramic manifolds was developed
· The size and weight and of the hotbox was reduced with a path identified for further reduction
· A gas control scheme was developed at the system level in line with that required for stable hotbox operation
With the work carried out during the project, we now believe that our hot box technology with co-sintered ceramic membrane could be competitive in several years.
