“…However, operating with large and fast transients in a load power is likely to drastically reduce the service life of the fuel cell, mainly due to failure, by various mechanisms, of the cells' membrane-electrode assemblies [14][15][16]. Fuel cell hybrid propulsion systems allow, by adopting appropriate energy management strategies [17][18][19][20][21], the use of the fuel cell as a stationary power generator. The energy stored in the battery systems and in the ultracapacitor provides a double benefit; preserving the life of the fuel cell and achieving a better dynamic response to load variations, as shown in Figure 2.…”

“…In the case of the given application, the control strategy was based on a state machine (SM) map strategy [34,35]. The management strategy was designed to meet several requirements: to preserve the fuel cell lifetime by avoiding an insufficient supply of reactants (fuel cell starvation) and by limiting the supplied current rate to a maximum of 40 A/s [17]; for efficient battery system operation, the battery SoC was kept above 60% at all times. The voltage on the DC bus (or UC SoC) was regulated by controlling DC/DC converter 1 of the cell [36][37][38].…”

Recent environmental and climate change issues make it imperative to persistently approach research into the development of technologies designed to ensure the sustainability of global mobility. At the European Union level, the transport sector is responsible for approximately 28% of greenhouse gas emissions, and 84% of them are associated with road transport. One of the most effective ways to enhance the de-carbonization process of the transport sector is through the promotion of electric propulsion, which involves overcoming barriers related to reduced driving autonomy and the long time required to recharge the batteries. This paper develops and implements a method meant to increase the autonomy and reduce the battery charging time of an electric car to comparable levels of an internal combustion engine vehicle. By doing so, the cost of such vehicles is the only remaining significant barrier in the way of a mass spread of electric propulsion. The chosen method is to hybridize the electric powertrain by using an additional source of fuel; hydrogen gas stored in pressurized cylinders is converted, in situ, into electrical energy by means of a proton exchange membrane fuel cell. The power generated on board can then be used, under the command of a dedicated management system, for battery charging, leading to an increase in the vehicle's autonomy. Modeling and simulation results served to easily adjust the size of the fuel cell hybrid electric powertrain. After optimization, an actual fuel cell was built and implemented on a vehicle that used the body of a Jeep Wrangler, from which the thermal engine, associated subassemblies, and gearbox were removed. Once completed, the vehicle was tested in traffic conditions and its functional performance was established.

There is large demand for better fuel economy on vehicles, researching different hybrid methods is necessary. The objective of this research is to use clean fuel for transportation like hydrogen & solar energy and to reduce the drawbacks of fossil fuels. The main drawback of fossil fuels is that they produce Green-house gases, non-sustainable, and having higher cost. The awareness for the environment has induced the development of different types of electric vehicles. While hydrogen & solar both are free in nature, sustainable energy, and are having zero emissions. These vehicles will be quite and eco-friendly without losing the power or range of the actual ones. We propose a hybrid energy system which combines both solar panel and hydrogen gas which will be a better alternative for conventional source of power generation to run the vehicle. All the more critically, there is poor air quality related with fossil fuel burning and the approaching issue of man-made environmental change. Due to this reality it is essential that we create transportation strategies so that we don't depend on fossil fuel as the primary source.

Energy management Hydrogen consumption Car autonomyRoad profile a b s t r a c t Climate change can be caused by a major part from the high fossil fuel usage and consumption in transportation field. It contributes to the increase of pollutant emissions, which lead to serious problems on human health in addition to the environmental degradation phenomena. Hydrogen fuel cell vehicles (FCVs) are expected to have a significant impact in meeting both energy security and environmental concerns globally.Starting for the premise that public acceptance and attitudes studies were generally positive towards hydrogen and fuel cells vehicles, even if the public knows few things about this technology; authors then got the idea to present a simplified scientific work dealing with the description of the energy management and flows calculations on board FCVs. This work aims not only to the popularization of this technology but also to outreach people about its sustainable character. A variable driving profile is adopted with a total distance of 1 km with duration of 60 s. The total hydrogen amount consumed is 1,34 g km À1. Under pressure, only 5 kg of hydrogen give optimal autonomy of 700 km, which is really competitive to the conventional gasoline cars. A nice advantage is yet observed and its concerns the environmental profits.Crown
