Fuel cell is a promising renewable energy source alternative for fossil fuel, used for electricity generation. Conventionally, a coal based thermal power plants are used for generating power. This requires, power plants to be synchronized with grid in terms of voltage and frequency. The main limitation in using coal based power plants are greenhouse gas emission which causes global warming. Fuel cell based power generation is clean and green. It uses hydrogen as a fuel which in turn is obtained from water by reverse electrolysis which is also green. The main issue is synchronization of fuel cell with grid in terms of grid voltage and frequency which is being addressed here. For synchronization, we need power conditioning units apart from fuel cell. A proton exchange membrane fuel cell (PEMFC) has been mostly used for power generation and the same has been discussed in this paper. Another issue is unstable voltage output as the load is increased. In this context, the techniques mentioned in previous literature, used for synchronization of fuel cell with grid has been reviewed. A brief description of the method used for synchronization is also mentioned here. Finally the results and conclusions are drawn at the end of the research paper.
