The present paper proposes an advanced approach for Polymer Electrolyte Membrane Fuel Cell (PEMFC) systems fault detection and isolation through a model-based diagnostic algorithm. The considered algorithm is developed upon a lumped parameter model simulating a whole PEMFC system oriented towards automotive applications. This model is inspired by other models available in the literature, with further attention to stack thermal dynamics and water management. The developed model is analysed by means of Structural Analysis, to identify the correlations among involved physical variables, defined equations and a set of faults which may occur in the system (related to both auxiliary components malfunctions and stack degradation phenomena). Residual generators are designed by means of Causal Computation analysis and the maximum theoretical fault isolability, achievable with a minimal number of installed sensors, is investigated. The achieved results proved the capability of the algorithm to theoretically detect and isolate almost all faults with the only use of stack voltage and temperature sensors, with significant advantages from an industrial point of view. The effective fault isolability is proved through fault simulations at a specific fault magnitude with an advanced residual evaluation technique, to consider quantitative residual deviations from normal conditions and achieve univocal fault isolation

“…Given the difficulty in experimentally capturing the interface of a gas-liquid or liquid-solid in the GDL of fuel cells, simulation approaches provide a good option. An analytical model (Pasaogullari and Wang, 2004), numerical model (Polverino et al, 2013), mean value model (Esposito et al, 2010b), and full morphology (Schulz et al, 2007) have been applied to study water behavior in the GDLs. Meanwhile, considering the porous GDL in a micro perspective, pore level simulation approaches, such as the lattice Boltzmann method (LBM), are favored by researchers.…”

Water transport and heat transfer are two critical issues for proton exchange membrane fuel cell (PEMFC) commercialization. Proper water and heat management ensure a sufficient reactant transport to reaction sites and high operating temperature, which requires good understanding of water and heat transport in PEMFCs. In this paper, previous studies about interfacial phenomena related to water transport and heat transfer in PEMFCs are reviewed. The interfacial phenomena in different components are discussed in detail. Experimental works have been conducted to visually observe the liquid water interface in PEMFCs. However, difficulty still remains for investigations of interfacial phenomena. Modeling works on interfacial phenomena in PEMFCs involve lattice Boltzmann, pore network, level set, and volume-of-fluid approaches. Different approaches have been applied for different components of PEMFC, and the liquid water interface can be located in all these approaches. Heat transfer in PEMFCs is also introduced. Various heat sources result in diverse heat transfer phenomena and nonuniform temperature distribution in PEMFCs. The components significantly influence heat transfer in PEMFCs. Coupled heat and water transport is a major issue for PEMFC management, and the heat pipe effect has been identified as an important mechanism of coupled heat and water transport. Cooling is important for PEMFC heat management, especially for PEMFCs with a large active area, high temperature, and stack.

“…Encouraged by works on the study of the pre-given water inside channel, many works begin to investigate the motions of water generating from the GDL, moving in the channel and draining out. Banerjee et al Polverino et al [11] proposed a numerical model of a droplet growing on the gas diffusion layer (GDL) surface is to describe the interaction between droplet and gas flow. Kotaka et al [12] studied the impact of wettability of bipolar plate on water transport.…”
