Based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. However, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. To resolve this problem, hybridization of the fuel cell and energy storage device...

In this study, a more accurate model of fuel cell of molten carbonate was also used that was determined input and output control variables and investigated the behavior of the system with respect to those variables. A more complete kinetic is also implemented for increasing the effectiveness of the presented paper. The input variables include fuel flow rate of cell which is methane and cell vol...

A computer controlled direct gasoline fuel injection (DGI) system has been modeled, programmed and constructed for a four-stroke SI engine. Locally available materials have been used for this experimental model. All the old model vehicle were equipped with carburetor for air fuel mixing and later on electronic fuel injection system has been introduced for maintaining better air fuel ratio and m...

The paper presents a Supervision, Control, Data Acquisition and Simulation (SCADA & Simulator) system that allows for real-time training in the actual operation of a modular PEM fuel cell system. This SCADA & Simulator system consists of a free software tool that operates in real time and simulates real situations like failures and breakdowns in the system. This developed SCADA & Simulator syst...

This paper describes a methodology for design and optimization of a polymer electrolyte membrane (PEM) fuel cell unmanned aerial vehicle (UAV). The focus of this paper is the optimization of the fuel cell propulsion system and hydrogen storage system for a baseline aircraft. Physics-based models, and experimentally-derived sub-system performance data are used to characterize the performance of ...

Due to the necessity of using highly efficient power generation systems to reduce fuel consumption and air pollution, the integration of different energy systems is promising modification to achieve higher efficiency. In this paper, the integration of an Internal Reforming Solid Oxide Fuel Cell (IRSOFC)-Gas Turbine (GT)-Organic Rankine Cycle (ORC) system has been proposed. In this regard, therm...

The consumption of oil fuel in Java shows that more than 70% of oil fuel is consumed in metropolitan cities, 14.2% is consumed in big cities, and 15.67% is consumed in medium cities. The variables of urban transport system powerfully influencing on oil fuel consumption are motor vehicles and roads. The influence of city typology (the number of population and) on oil fuel consumption is greater ...

This study based on investigation for integration wind power into conventional power system with its impact on fossil fuel generators and their generation management. Wind power as environmental friendly energy source can reduce the operational cost of the system due to considering no cost for energizing the generator in comparing with fossil fuel generators. However due to unpredictable nature...

A fuel-supply system using movable fuel-supply vehicles (FSVs) is proposed and its performance is evaluated. Both FSVs and vehicles requesting fuel are equipped with networked sensors. The sensors in FSVs are location sensors, and those in vehicles requesting fuel are for determining the remaining amount of fuel and the location of the vehicle. The time from when a fuel request is generated unt...
