This meta-study focuses on the research regarding the use of nanotechnology in traditional fuel cells in order to increase thermodynamic efficiency through the exploitation of various thermodynamic systems and theories. The use of nanofilters and nano-structured catalysts improve the fuel cell system through the means of filtering molecules from protons and electrons significantly increases the possible output of the fuel cell and the use of nano-platinum catalysts to lower the activation energy of the fuel cell chemical reaction a notable amount resulting in a more efficient system and smaller entropy in comparison to the use of macro sized catalysts.

In the most recent period, gasoline and diesel are still the main energy sources of the car. The new energy vehicles need to be solved in the near future. The new medium of the internal combustion engine and the alternative combustion vehicles. The medium-term scheme is to reduce the fuel consumption and emissions of the hybrid vehicles. The program is pure electric vehicles and fuel cell vehicles. While new energy vehicles offer a wide range of alternative fuels for fuel-based fuels, hybrid vehicles, and fuel cell vehicles that use fuel and power systems for automotive hydrogen fuel cells, but because of the current level of technological development, search for a wide range of alternative fuels, the development of closer to the market of hybrid technology, is the development of alternative energy is the most practical step. And pure electric vehicles and hydrogen fuel cells because of its technology is still difficult to achieve a revolutionary breakthrough, it is difficult to become the automotive industry's recent development goals. In today's social situation, the hybrid can be a better solution to fuel consumption problems and pollution problems. It will mainly introduce the advantages and feasibility of hybrid.

The issues of mathematical and numerical simulation of an electrical complex of a power plant based on hydrogen fuel cells with a voltage step-down converter were considered. The work was aimed at developing a mathematical model that would provide for determining the most loaded operation mode of the complex components. The existing mathematical models do not consider the effect of such processes as the charge and discharge of the battery backup power supply on the power plant components. They often do not consider the nonlinearity of the fuel cell output voltage. This paper offers a mathematical model of an electrical complex based on the circuit analysis. The model combines a well-known physical model of a fuel cell based on a potential difference and a model of a step-down converter with a battery backup power supply developed by the authors. A method of configuring a fuel cell model based on the experimental current–voltage characteristic by the least-squares method has been proposed. The developed model provides for determining currents and voltages in all components of the power plant both in the nominal operating mode and in the mode of limiting the power consumed from the fuel cell when the battery backup power supply is being charged. The correctness of the calculated ratios and the mathematical model has been confirmed experimentally. Using the proposed model, a 1300 W power plant with a specific power of 529.3 W∙h/kg was developed and tested.

Fuel cells having a high energy conversion efficiency with low restriction of installation space is rising as a new eco-friendly renewable energy source. Fuel cells are largely divided into MCFC, SOFC, PEMFC, DMFC, etc. according to the type to be transferred. In this study the four fields were analyzed from a diversity aspect, a social network aspect and a distance aspect. Results showed PEMFC and MCFC to apply the most diverse technology, and catalyst technology and hydrogen fuel manufacturing areas were observed developing in all four fields. In addition, many studies were found to be commonly conducted for fuel cell vehicles in the PEMFC and SOFC fields. PEMFC is expected to have the highest effect with technology development, specifically commercialization of the Fuel Cell Vehicles through an active technology development. Development in the SOFC and MCFC fields are expected to promote home fuel cell use.
