It sounds so simple. Just combine oxygen and hydrogen in an electrochemical reaction that produces water and electricity, and you'll have a clean, efficient power source. But scientists have spent decades--and billions of dollars in government and industry funding--developing the fuel cell. There have been successes and serendipitous discoveries along the way, but engineering a fuel cell that is both durable and affordable has proved extraordinarily...
