The solid oxide fuel cell (SOFC) has much higher energy efficiency than combustion-based energy conversion. This efficiency, coupled with its environmentally friendly nature, makes it a favorable candidate as part of the solution for todays increasing demand for energy spurred by economic development, population increase, and competition for limited fossil fuels. Out of all other types of fuel cells, the SOFC shows higher efficiencies and greater fuel flexibility because of its higher operating temperature. The concept of generating electrical power from SOFCs fueled by ...
