Not in their cars, but in their plants. Ford first tested the idea in their Rouge assembly complex in Dearborn, MI. This application will be in the Oakville, Ontario plant. The process collects fumes from the manufacturing plant's paint shop and feeds the fumes into a fuel cell instead of releasing them as emissions. The fuel cell then creates electricity for the plant by generating it from the hydrocarbons in the fumes. Oakville currently builds the Ford Freestar and Mercury Monerey minivans.
