  • WP1. Project and R&D management and coordination

    This work package will address all activities related to planning, co-ordination, progress monitoring and dissemination of project reports to the European Commission. Furthermore, inter-project definitions and specifications will be condensed and continuously updated. Within the two targeted tasks of i) Project coordination and ii) Operational & Financial Administration the required tools and procedures, needed for a professional and successful project management, will be provided, matched to the complexity of the project.

  • WP2. Materials preparation and characterization

    The activities of WP2 are focused on the preparation of modified NiO/GDC (GDC: gadolinia doped ceria) and NiO/YSZ (YSZ: yttria stabilized zirconia) anode powders, their complete physico-structural characterization and finally the preparation of all single triode cells which will be tested in WP2.

  • WP3. Triode SOFC operation

    This work package is aimed at the study of the effect of triode SOFC operation on fuel cell performance and on degradation phenomena due to carbon formation and sulphur poisoning of modified Ni-based cermet anodes. The experimental work includes the operation of the cells prepared in WP2, in normal and constant/pulse triode mode, fueled with (a) hydrogen or H2/H2O mixtures and (b) dry methane in absence or presence of co-fed methane and steam and also in the absence and presence of sulphur compounds. Triode operation is expected to enhance both fuel cell performance and anode durability. These results, combined with input from WP2 regarding anode failure mechanisms, will provide direct insight into the causes of anode failure and necessary input data for the mathematical modeling of triode operation and optimization.

  • WP4. Mathematical modeling and optimization

    A detailed mechanism molecular-level will be proposed, accounting for all electrochemical processes taking place within a triode cell. Based on this, a model that predicts the behavior of triode cells as a function of design and operation parameters will be developed.
    WP Leader: École Polytechnique Fédérale de Lausanne (EPFL)

  • WP5. Triode stack development and operation

    A stack consisting of at least 4 repeating triode single cells will be designed and constructed. It will then be operated under varying triode SOFC operation conditions for short and long-term periods.
    WP Leader: SOFCpower

  • WP6. Dissemination and use of knowledge

    Dissemination of the results to the scientific community and to the wider public.
