Abstract
This paper deals with the modeling and simulation of suitable DC-DC converters for Fuel cell system. In the field of renewable energies, power electronics and fuel cell technologies play an important role. As the fuel cells become the main power source for portable applications, demand for fuel cells will increase. A highly efficient converter is an essential requirement in this application and a core parameter of the device as a whole. Therefore, a high efficient converter has to be designed for fuel cell system as the output voltage of fuel cell is low. In this paper, various DC-DC converters such as Boost converter, SEPIC, LUO converter and ZETA converter with fuel cell as an input source are designed and the same is simulated using MATLAB. Total Harmonic Distortion analysis of all the DC-DC converters is carried out and the suitable converter for fuel cell application is selected based on the low Total Harmonic Distortion value.

Summary
Compared with traditional fossil-fuel systems, renewable energy systems deliver environmental and economic advantages in energy production. Fuel cells are the most common among all forms of green energy applications since they can provide a continuous supply of power throughout all seasons as long as fuel is supplied. Industrialists from various sectors (electronics, cell phones, automobiles, power generation, heating, etc.,) are investing in the production of this high-density technology with low harmful gas emissions [3], [4]. There are various types of FCs, distinguished by their electrolytes. The polymer electrolyte membrane FC (PEMFC) is one of the most promising to be used for stationary or transported applications due to its relatively small size, simple design, lightweight, and low operating temperature [5], [6]. Membranes FCs are composed of two compartments of electrodes separated by a polymer electrolyte membrane to prevent the movement of gas and electrons. The two electrodes are placed on the side of the membrane, creating the individual cell's membrane – electrode assembly (MEA)
