Fuel cells have several important advantages over conventional electrical energy generation from sources such as fossil fuels. Although, this relatively developing technology have several problems, that should be solved. In addition to technological problems, such as high costs, several changing the materials, fuel reforming, long start up time, degradation over time, low voltage, source of materials, special catalyst, some environmental problems may be created by growing this technology. In this paper we hope to introduce and discuss several aspects of disadvantages of fuel cells.
