The INSIGHT project aims at developing a Monitoring, Diagnostic and Lifetime Tool (MDLT) for Solid Oxide Fuel Cell (SOFC) stacks and the hardware necessary for its implementation into a real SOFC system. The effectiveness of the MDLT will be demonstrated through on-field tests on a real micro-Combined Heat and Power system (2.5 kW), thus moving these tools from Technology Readiness Level (TRL) 3 to beyond 5. INSIGHT leverages the experience of previous projects and consolidates their outcomes both at methodological and application levels. The consortium will specifically exploit monitoring approaches based on two advanced complementary techniques: Electrochemical Impedance Spectroscopy (EIS) and Total Harmonic Distortion (THD) in addition to conventional dynamic stack signals. Durability tests with faults added on purpose and accelerated tests will generate the data required to develop and validate the MDL algorithms. Based on the outcome of experimental analysis and mathematical approaches, fault mitigation logics will be developed to avoid stack failures and slow down their degradation. A specific low-cost hardware, consisting in a single board able to embed the MDLT will be developed and integrated into a commercial SOFC system, the EnGenTM 2500, which will be tested on-field. INSIGHT will then open the perspective to decrease the costs of service and SOFC stack replacement by 50%, which would correspond to a reduction of the Total Cost of Ownership by 10% / kWh. To reach these objectives, INSIGHT is a cross multidisciplinary consortium gathering 11 organisations from 6 member states (France, Italy, Denmark, Slovenia, Austria, Finland) and one associated country (Switzerland). The partnership covers all competences necessary: experimental testing (CEA, DTU, EPFL), algorithms developments (UNISA, IJS, AVL), hardware development (BIT), system integration and validation (VTT, SP, HTC), supported by AK for the project management and dissemination.

Embedded systems have significantly increased in technical complexity towards open, interconnected systems. This has exacerbated the problem of ensuring dependability in the presence of human, environmental and technological risks. The rise of complex Cyber-Physical Systems (CPS) has led to many initiatives to promote reuse and automation of labor-intensive activities. Two large-scale projects are OPENCOSS and SafeCer, which dealt with assurance and certification of software-intensive critical systems using incremental and model-based approaches. OPENCOSS defined a Common Certification Language (CCL), unifying concepts from different industries to build a harmonized approach to reduce time and cost overheads, via facilitating the reuse of certification assets. SafeCer developed safety-oriented process lines, a component model, contract-based verification techniques, and process/product-based model-driven safety certification for compositional development and certification of CPSs. AMASS will create and consolidate a de-facto European-wide assurance and certification open tool platform, ecosystem and self-sustainable community spanning the largest CPS vertical markets. We will start by combining and evolving the OPENCOSS and SafeCer technological solutions towards end-user validated tools, and will enhance and perform further research into new areas not covered by those projects. The ultimate aim is to lower certification costs in face of rapidly changing product features and market needs. This will be achieved by establishing a novel holistic and reuse-oriented approach for architecture-driven assurance (fully compatible with standards e.g. AUTOSAR and IMA), multi-concern assurance (compliance demonstration, impact analyses, and compositional assurance of security and safety aspects), and for seamless interoperability between assurance/certification and engineering activities along with third-party activities (external assessments, supplier assurance).

Cyber-Physical-Systems harbor the potential for vast economic and societal impact in all major application domains, however in case of failure this may lead to catastrophic results for industry and society. Thus, ensuring the dependability of such systems is the key to unlocking their full potential and enabling European industries to develop confidently business models that will nurture their societal uptake. The DEIS project addresses this challenges by developing technologies that form a science of dependable system integration. In the core of these technologies lies the concept of a Digital Dependability Identity (DDI) of a component or system. DDIs are composable and executable in the field facilitating (a) efficient synthesis of component and system dependability information over the supply chain and (b) effective evaluation of this information in-the-field for safe and secure composition of highly distributed and autonomous CPS. This concept shall be deployed and evaluated in four use cases: Automotive: Stand-alone system for intelligent physiological parameter monitoring Automotive: Advanced driver simulator for evaluation of automated driving functions Railway: Plug-and-play environment for heterogeneous railway systems Healthcare: Clinical decision support app for oncology professionals The DEIS project will impact the CPS market by providing new engineering methods and tools reducing significantly development time and cost of ownership, while supporting integration and interoperability of dependability information over the product lifecycle and over the supply chain. The development and application of the DDI approach on four use cases from three different application domains will illustrate the applicability of the DDI concept while increasing the competitiveness of the use case owners in their respective markets.
