It is simple, yet extremely fuel efficient, because we took a systems approach to optimize fuel economy. The LSR design requires only very modest energy storage - less than that of a conventional starter battery, but at higher power and voltage. Thus, LSR improves cost and reduces complexity compared to other hybrid designs. It also can assist the engine as the vehicle accelerates and support the brakes during deceleration, thus recharging the battery for later use. Although an LSR hybrid is simpler, lighter, smaller and less costly than other hybrid vehicles, it can supply the performance that customers expect from a Ford.
Fuel cells have several advantages over batteries, which currently have range and durability limits.
However, many challenges remain, including packaging, development of a hydrogen supply infrastructure and affordability compared with conventional vehicles. Ford is researching the vehicle's fuel cells in partnership with Ballard Power Systems of Canada and DBB Fuel Cell Engines. Fuel cells are energy conversion devices that generate electricity from hydrogen and oxygen without combustion. Hydrogen fuel, which can be made from either natural gas or methanol, is electrochemically combined with oxygen from the air to produce electricity. The only emission from the fuel cell is water vapor.
