“…In contrast, Hahn et al [27] have present the optimization of the efficiency (increased by 3.5%) and degradation rate (reduced by 2%) for an automotive fuel cell system. In addition, a similar study was presented by [28] on the dynamic reliability assessment of PEM fuel cell systems using only simulation measurements. They claim that fuel cell systems are likely to fail after 4000 working hours.…”

This comprehensive review explores recent developments in Proton Exchange Membrane Fuel Cells (PEMFCs) and evaluates their alignment with the ambitious targets established by the U.S. Department of Energy (DOE). Notable advancements have been made in developing catalysts, membrane technology advancements, gas diffusion layers (GDLs), and enhancements in bipolar plates. Notable findings include using carbon nanotubes and graphene oxide in membranes, leading to substantial performance enhancements. Innovative coatings and materials for bipolar plates have demonstrated improved corrosion resistance and reduced interfacial contact resistance, approaching DOE targets. Nevertheless, the persistent trade-off between durability and cost remains a formidable challenge. Extending fuel cell lifetimes to DOE standards often necessitates higher catalyst loadings, conflicting with cost reduction objectives. Despite substantial advancements, the ultimate DOE goals of USD 30/kW for fuel cell electric vehicles (FCEVs) and USD 600,000 for fuel cell electric buses (FCEBs) remain elusive. This review underscores the necessity for continuous research and innovation, emphasizing the importance of collaborative efforts among academia, industry, and government agencies to overcome the remaining technical barriers.

“…Numerous approaches have been documented in the literature for assessing the reliability of complex dynamic systems and diagnosing faults (Liu and Zio, 2017;Shukla and Arul, 2020;Vasilyev et al, 2021;Xu et al, 2023). One promising research direction involves integrating Bayesian Network features into a Petri Net model.…”

The existing Generalised Stochastic Petri Net and modified Bayesian Stochastic Petri Net (GSPN-mBSPN) methodology has demonstrated improved modelling capabilities for fault diagnosis in dynamic systems with feedback control loops. However, the GSPN-mBSPN approach uses predefined input conditional probability tables (iCPTs) for fault diagnosis, limiting its usage in dynamic fault diagnosis due to the time required to define and populate the iCPT entries accurately. This paper presents an algorithm to automatically generate iCPT tables, enhancing the modelling capability of the GSPN-mBSPN approach for fault diagnosis of dynamic systems under time-varying conditions. The GSPN module in a GSPN-mBSPN model of a dynamic system is analysed and structured into sub-net modules, representing system components, monitoring parameters, and interactions. These sub-net modules provide data structures for the iCPT tables, describing the working and failure states/modes of system components, states of the monitoring parameter, and causal relationships between system component states and observable process parameters. The algorithm populates the entries of the iCPT tables based on the analysis of the sub-net modules. Application of the algorithm to a water tank level control system demonstrates improved speed and accuracy in generating iCPTs for dynamic fault detection and diagnosis applications using GSPN-mBSPN approach.
