Technoride reports: "The most attractive feature of SOFC (Solid Oxide Fuel Cells) systems are their fuel flexibility. Because they can run on a variety of fuels, or electrolytes, SOFCs eliminate the need to provide hydrogen as a source of fuel. But being able to run on multiple widely available petrochemical fuels also frees American automakers from dependency on any one fuel in case of a shortage. Franklin Fuel Cells believes its improved SOFC technology is key in enabling smooth transition off of fossil fuels, the company has said."
It's an interesting concept engine, I wonder if we will ever see it in production. Although I am still waiting for the time when I can to run my car on water.
