Coupled with the accelerated search of "clean generation" electric energy is growing need for alternative source in urban transportation that can reduce overall impact on air pollution. Hybrid vehicles, HEV, are offering best possibility use new sources, because electricity result from a transformation high efficiency system drives and components. In this paper authors pretend to show possible application particular motion system, joint JS, simplified HEV model. A special management strategy...
Hybridization with high specific energy-storage devices such as supercapacitors (SCs) has important advantages in fuel-cell (FC)-based systems. This paper presents an approach for the design and analysis of FC hybrid systems (FCHSs) oriented to automotive applications. The FCHS is considered be most attractive long-term option propulsion passenger cars. stage includes determination electrical topology hybridization degree (HD) according drivability conditions. With selected design, optimal...
Electrolyte imbalance is the main cause of capacity loss in vanadium redox flow batteries. It has been widely reported that caused by crossover can be readily recovered remixing electrolytes, while a net oxidation electrolyte only reverted means more complex chemical or electrochemical methods. At moment, however, joint effect both types imbalances on battery still not well understood. To overcome this limitation, generalised State Charge and Health indicators consider are derived work....
The aim of this research is to develop and test in a simulation environment an advanced model-based control solution for proton exchange membrane fuel cell (PEMFC) system. A nonlinear model-predictive (NMPC) strategy proposed maximize the active catalytic surface area at cathode catalyst layer increase available reaction stack avoid starvation sites. PEMFC model includes spatial discretization that permits take into account internal conditions These states are estimated fed NMPC via...
This paper presents a novel observer architecture capable to estimate online the concentrations of four vanadium species present in redox flow battery (VRFB). The proposed comprises three main stages: (1) high-gain observer, output voltage and its derivatives; (2) dynamic inverter, obtain set concentration candidate solutions; (3) static selector, determine actual concentrations. methodology does not rely on classic assumption balanced electrolytes, thus significantly widening application...
The number of Fuel Cell Electric Vehicles (FCEVs) in circulation has undergone a significant increase recent years. This trend is foreseen to be stronger the near future. In correlation with FCEVs market increase, hydrogen delivery infrastructure must developed. With this aim, many countries have announced ambitious projects. For example, Spain objective increasing Hydrogen Refuelling Stations (HRS) public access from three units operation currently about 150 by 2030. HRSs are complex...
In this work, the controllability of different distillation arrangements for separation ternary mixtures is compared. At same time, energetic efficiency each one analyzed. Specifically, direct and indirect sequences columns, columns with side sections, divided wall column (DWC) are considered. To compare arrangements, preferred control structures searched. For DWC, operating conditions that favor discussed. Also, have been compared under design conditions.
This paper presents a nonlinear observer to estimate the active species concentrations in vanadium flow batteries. To conduct estimation, relies only on current, rate and two half-cell voltage measurements. In contrast previous works field, proposed is capable deal simultaneously with significant challenging conditions: (1) not necessarily high rate, which results different for tanks cells, (2) presence of crossover oxidation side reactions, that result imbalance between electrolytes...
A comparative study of the corrosion behaviour WC-Co based hardmetals with Ni and Cr3C2 additions is carried out. The aggressive environments are neutral acidic aerated aqueous solutions NaCl H2SO4. This on electrochemical (linear sweep voltammery), compositional (surface EDX analyses, AAS analyses attack solutions), structural (XRD) morphological (SEM) investigations. Electrochemical figures merit were computed from linear voltammograms in order to rank close free-immersion conditions...
Continuous developments in Proton Exchange Membrane Fuel Cells (PEMFC) make them a promising technology to achieve zero emissions multiple applications including mobility. Incremental advancements fuel cells materials and manufacture processes now suitable for commercialization. However, the complex operation of cell systems automotive has some open issues yet. This work develops compares three different controllers PEMFC applications. All have cascade control structure, where generator...
