100% ethanol or aqueous ethanol are mixed with air in a reformer, and the hydrogen generated enters an SOFC stack, where hydrogen reacts with oxygen to produce electrical energy for a battery. Nissan claims that this new energy system allows vehicles to achieve the same mileage as with gasoline vehicles, with up to 370 miles per battery load. As the cost of storing the water-soluble alcohol is much lower than that of hydrogen, and security is higher, this technology is considered superior by Nissan.
