METPROCELL Project "Innovative fabrication routes and materials for METal and anode supported PROton conducting fuel CELLs" is a European 2010 FCH-JTI project (2012-2014). It approaches in the range 400-700°C of temperature operation the development of innovative proton conducting cells (PCC) as both electrolyser (PCEC) and fuel cell (PCFC) devices by using new electrolyte and electrode materials and by implementing cost effective fabrication routes. Following a complementary approach, the cell architecture is studied on both metal and anode type supports, with the aim of improving the performance (>400 mW/cm2, 600°C), durability (> few thousand hours) and cost effectiveness of the cells (vs. SOFC). Specific objectives are:
  • The development at high scale of perovskite based electrolyte and corresponding anode materials synthesis processes with enhanced properties for improved proton conducting fuel cells dedicated to 500-600°C.
  • The development of alternative manufacturing routes using cost effective thermal spray technologies such detonation spraying (electrolytes and protective coatings on interconnects) and plasma spraying (anode) and/or wet chemical processes (screen-printing, tape casting...).
  • The development of innovative proton conducting fuel cell configurations to be constructed on the basis of both metal supported and anode supported cell designs.
  • To up-scale the manufacturing procedures based on both conventional wet chemical methods and thermal spraying for the production of flat Stack Cells with a footprint of 12 x 12 cm.
  • To bring the proof of concept of these novel PCFCs by the set-up and validation of prototype like stacks in two relevant industrial systems, namely Auxiliary Power Unit (APU) and gas/micro- Combined Heat and Power (micro-CHP).
  • The PCC technology could significantly contribute to industrialise the fuel cell and electrolyser technology by improving the cell characteristics (higher thermal cycling, better heat transfer and current collection, better energetic efficiency...) and lowering drastically the system costs.
