An investigation on using PEM Fuel cell at residential power system

The importance of using renewable energy sources is increasing day by day. In addition, there are some physical and economic difficulties in delivering electrical energy to each end user. The most important factor in overcoming these situations is to create the end user who can feed in isolation. In this research, an end-user profile, which is isolated from the grid and provides its energy by using a battery-backed PEM fuel cell, has been examined in the simulation environment within the scope of the scenarios created. The systems that are intended to be implemented in reality have been transferred to the simulation environment, thus feeding the end user. Here, in order to prevent deep discharge and overcharging of the battery block, the fuel cell is kept in operation for the critical states of minimum 40% and maximum 90% charge, and the simulation results are given. Afterwards, the current prices and initial investment, operation and maintenance costs for a battery-assisted fuel cell supply system are analyzed and the results are presented.
