“…The FC stack is considered to fail whenever it is not able to provide the required power output (Fecarotti et al, 2016). The required lifetime of SFC MEA is up to 40 000 h to be considered economically feasible (Knights et al, 2004;Belvedere et al, 2013;Fecarotti et al, 2016).…”

“…A probabilistic model is used to estimate the operation lifetime of a fuel cell, to calculate the required number of units to be produced for replacement, and to estimate the number of units that come out of service for EoL processing. Fecarotti et al (2016) propose a Weibull distribution model and provide results on the lifetime of a PEMFC based on modelling the failure of the different components. A maximum average lifetime of 14 246 h is estimated, around 3 years of operation ( Figure 1).…”

<p>Due to the pressing necessity of switching to alternative sources of energy, fuel cells (FC) for household applications have emerged as an alternative for decentralized energy supply. Despite the advancement on technological developments, concerns on the availability of critical raw materials required for the fabrication of these technologies may limit their implementation. This document analyses the demand of platinum for mass implementation of stationary fuel cells for household energy supply in Germany, through an analysis of the potential market, lifecycle of the product, material demands, and material flows. Different scenarios show that improving recycling rates and extending operation lifetime can help to mitigate the material needs even in the most demanding scenarios and reach material reuse targets. Methods and results can also be applied for other regions where FC have this potential applicability. Quality of data and its effects on the results need also to be further analyzed.</p>

“…The authors designed 21 Petri net sub-modules corresponding to various degradation phenomena such as radical attack and start-up/shut-down cycles. Paper by (Fecarotti et al 2016) presented an extended Petri net modelling approach for representation of auxiliary components together with the fuel cell stack. Monte Carlo simulations provided estimation of expected lifetime of the system under certain operating conditions and maintenance schedule.…”

In this paper, a novel model for dynamic reliability analysis of a PEM fuel cell system is developed using Modelica language in order to account for multi-state dynamics and aging. The modelling approach constitutes the combination of physical and stochastic sub-models with shared variables. The physical model consist of deterministic calculations of the system state described by variables such as temperature, pressure, mass flow rates and voltage output. Additionally, estimated component degradation rates are also taken into account.The non-deterministic model, on the other hand, is implemented with stochastic Petri nets which represent different events that can occur at random times during fuel cell lifetime. A case study of effects of a cooling system on fuel cell performance was investigated. Monte Carlo simulations of the process resulted in a distribution of system parameters, thus providing an estimate of best and worst scenarios of a fuel cell lifetime.

“…Regarding the emergency rescue process, existing studies have used multiple model-based methods to evaluate and optimize the flow of different types of rescue processes [12,13] . Petri nets have long demonstrated the dominance of their application in different fields as an effective approach to portray workflows [14,15] . Petri nets, as a powerful process modeling tool, can dynamically represent the coupling relationship in a system and accurately represent the behavior in the system [16] .…”

Stochastic Petri Net Based Modeling of Emergency Medical Rescue Processes during Earthquakes

et al. 2021

The post-disaster emergency medical rescue (EMR) is critical for people's lives. This paper presents a stochastic Petri net (SPN) model based on the process of the rescue structure and a Markov chain model (MC), which is applied to the optimization of the EMR process, with the aim of identifying the key activities of EMR. An isomorphic MC model is developed for measuring and evaluating the time performance of the EMR process during earthquakes with the data of the 2008 Wenchuan earthquake. This paper provides a mathematical approach to simulate the process and to evaluate the efficiency of EMR. Simultaneously, the expressions of the steady state probabilities of this system under various states are obtained based on the MC, and the variations of the probabilities are analyzed by changing the firing rates for every transition. Based on the concrete data of the event, the authors find the most time consuming and critical activities for EMR decisions. The model results show that the key activities can improve the efficiency of medical rescue, providing decision-makers with rescue strategies during the large scale earthquake.
