Compared to traditional combustion-based power generating technologies, fuel cell technologies are anticipated to significantly reduce oil consumption and emissions of pollutants including greenhouse gases. High efficiency is one of the extra benefits of fuel cell technology, and in some cases, this efficiency may be used for hybrid or cogeneration applications. Less focus has been made on material sources and the recovery of hardware materials, despite the fact that much has been done to advance fuel cell technology and emphasise its advantages for the environment.
