Abstract
A fuel cell is a device that converts the chemical energy of the fuel directly into electrical energy. Hydrogen gas is used as an ideal fuel in a fuel cell due to its high reactivity, abundance and lack of environmental pollution. In order to produce energy with optimal efficiency, the fuel cell series requires additional equipment called the fuel cell system, which optimal performance conditions for the fuel cell include fuel purity, the amount of air and fuel entering the fuel cell series, gas humidity and water management, temperature control and finally control the gas pressure in the fuel cell system and series. According to the type of fuel cell and its application, these systems are simple or complex, for example, in power plant fuel cells, the fuel converter part that converts fossil fuels, biomass into pure hydrogen, is the main and complex part of the fuel system. In automotive applications, the refueling system can take the following two forms depending on the type of fuel infrastructure: If hydrogen is produced at the refueling station, the vehicle fuel storage system can use different methods such as hydrogen storage in pressure tanks, Use of nanotubes, use of metal hydride absorbers, use of chemical hydrides. In case of hydrogen production in the car, the fuel converter (especially the gasoline and methanol converter) that can be installed on the car is the main and complex part of the fuel system in the car.
