SUMMARYReduction in greenhouse effect gases emission is a major source of concern nowadays. Internal combustion engines, as the most widely used power generation mean for transportation, represent a large share of such gases, which motivates active research efforts for alternative solutions. In this regard, PEM fuel cells represent a promising prospect and are thoroughly investigated, whether experimentally or through numerical simulation.The present work presents a simulation of the power potential of a PEM fuel cell, which is integrated to the full power electric traction chain of a medium size car. The cell potential is modelled by taking into account the different types of polarization. The driving performances of the vehicle and its hydrogen consumption are evaluated through a simple mathematical model and an application is performed for the New European Driving Cycle (NEDC) standard driving cycle. A preliminary sizing of the proton exchange membrane fuel cell (PEMFC) membrane area for the chosen vehicle is presented, along with that of a hydrogen storage tank for a typical autonomy. The main goal of the simulation is to estimate CO 2 indirect emissions due to the production of the needed hydrogen for the cycle via an electrolyser, compared with the case of a gasoline fueled vehicle. This is performed solely on a 'fuel tank to wheel' basis in order to have comparable figures. The results indicate that the environmental advantage of hydrogen cars is quite questionable if hydrogen is produced using carbon-based energy sources.
A fundamental, omnipresent feature of the global information age is that cyber-capabilities, e.g. computing, communication and control, are inherently embedded in numerous physical/engineered systems from the nano-world to largescale systems-of-systems. Many scientific/technological challenges require intensive multidisciplinary studies, calling for new formulations, techniques and innovative solutions from a spectrum of communities in systems engineering/control/communications. IJSCC offers a vibrant discussion forum in this interdisciplinary area, especially communication systems augmented by control techniques and control systems whose components are interconnected via communication networks.
Contents:IJSCC publishes original papers, review papers, technical reports, book reviews, notes and commentaries. Special Issues devoted to important and timely topics in integrated control and communication systems will occasionally be published.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
