The PEM's cathode and anode are separated by a thin polymer membrane that allows only the hydrogen ions to pass through. Ballard started out using membranes designed for other applications. The results have led to a mini rush among car manufacturers to fuel cell engines. DaimlerChrysler and Ford each own a share of Ballard, and Nissan and Honda have both ordered Ballard fuel cells. Now we begin the race to lower the cost to the level of today's internal combustion engine.
Cost remains the biggest hurdle to widespread adoption of fuel cells in cars.
Rasul is confident that Ballard can reach this goal with a combination of better and cheaper materials and refined manufacturing processes. Fuel cells, he adds, offer consumers more than cleanliness. The final objectives we are looking at are higher performance and better reliability, advantages beyond environmental friendliness.
