PCFC is one of the most promising technologies to reach the requirements related to cogeneration application, especially for small power systems (1-5 kWel). The investigation in the concept of advanced thin-film ceramic fuel cell technology at operating intermediate temperature between 400 and 700 C aims at improving the characteristics (thermal cycling, heat transfer, current collection,.) as well as lowering drastically the costs of the system. The aim of METPROCELL is to develop innovative Proton Conducting Fuel Cells (PCFCs) by using new electrolytes and electrode materials and implementing cost effective fabrication routes based on both conventional wet chemical routes and thermal spray technologies. Following a complementary approach, the cell architecture will be optimised on both metal and anode type supports, with the aim of improving the performance, durability and cost effectiveness of the cells. Specific objectives: - Development of novel electrolyte (e.g. BTi02, BCY10/BCY10) and electrode materials (e.g. NiO-BIT02 and NiO-BCY10/BCY10 anodes) with enhanced properties for improved proton conducting fuel cells dedicated to 500-600C. - Development of alternative manufacturing routes using cost effective thermal spray technologies such detonation spraying (electrolytes and protective coatings on interconnects) and plasma spraying (anode). - 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. - 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 APU and gas/micro CHP.

State of the art SOFC technology for stationary as well as for transportation application is to date being demonstrated with either planar or tubular ceramic anode-supported or electrolyte-supported SOFC cells. However, the SOFC technology faces many challenges when it comes to commercialization, since cost reduction, reliability and extended lifetime is required. In order to improve durability and cost efficiency of the cells the stacks and the system much of the development has in the past been focused on lower operation temperature, increased power density and material savings based on reduced cell and stack component thickness. Nevertheless, most of the demonstrations with ceramic cells in real system operation have until now revealed problems regarding these issues in combination with low robustness. Attention to these issues has especially been paid in connection with SOFC technology for mobile application, such as in APUs. Modelling studies as well as recent practical experience has proved how up-scaling of cells and stacks to larger more industrially relevant sizes generally leads to lower reliability in real system operation and intolerance towards system abuse and operation failures. These observations conform to the statistical distribution of mechanical properties governing the probability of failure of cells based on ceramic materials, whether it is for mobile or for stationary applications. The aim of the METSAPP project is to develop novel cells and stacks based on a robust and reliable up-scale-able metal supported technology with the following primary objectives: 1. Robust metal-supported cell design, ASRcell < 0.5 Ohmcm2, 650 C; 2. Cell optimized and fabrication upscaled for various sizes; 3. Improved durability for stationary applications, degradation < 0.25%/kh; 4. Modular, up-scaled stack design, stack ASRstack < 0.6 Ohmcm2, 650 C; 5. Robustness of 1-3 kW stack verified; 6. Cost effectiveness, industrially relevance, up-scale-ability illustrated.


A process for the conditioning of and applying a ceramic or other layer onto the surface of a sheet of stainless steel comprises the steps of (a) optionally annealing the steel plate or sheet in a protective gas atmosphere at an elevated temperature, (b) controlled etching of the surface of the sheet to produce a roughened surface and (c) depositing a protective and electrically conductive layer onto the roughened metallic surface. The process leads to coated metallic sheets with desirable properties, primarily to be used as interconnects in solid oxide fuel cells and solid oxide electrolysis cells.

The project will demonstrate a new full ceramic SOFC cell with superior robustness as regards to sulphur tolerance, carbon deposition (coking) and re-oxidation (redox resistance). Such a cell mitigates three major failure mechanisms which today have to be addressed at the system level. Having a more robust cell will thus enable the system to be simplified, something of particular importance for small systems, e.g. for combined heat and power (CHP). The new ceramic based cell will be produced by integrating a new, very promising class of materials, strontium titanates, into existing, proven SOFC cell designs. Cost effective and up-scalable processes will be developed for the fabrication of supports and cells. In an iterative process the cell performance at defined tolerance levels will subsequently be improved by adjustments of the fabrication on full cell level according to identified failure mechanisms. Cells with matching performance but improved sulphur, coling and re-oxidation tolerance compared to state-of-the-art Ni-cermet materials will finally be demonstrated in a real system environment.

The ADEL project (ADvanced ELectrolyser for Hydrogen Production with Renewable Energy Sources) proposes to develop a new steam electrolyser concept named Intermediate Temperature Steam Electrolysis (ITSE) aiming at optimizing the electrolyser life time by decreasing its operating temperature while maintaining satisfactory performance level and high energy efficiency at the level of the complete system including the heat and power source and the electrolyser unit. The relevance of this ITSE will be assessed both at the stack level based on performance and durability tests followed by in depth post test analysis and at the system level based on flow sheets and energy efficiency calculations.
