Large solid oxide fuel cells
(SOFC) like the one in the photo to the right (see yesterday's related story here
) isn't going to be fitting into any cars any time soon, but the technology behind it might. Researchers at Tufts University have found a way to continuously remove the sulfur that builds up in high-temperature fuel cells, according to Technology Review
. Removing the sulfur is key because the fuel cells use fossil fuels (coal, oil, and natural gas
) to generate hydrogen
. High temperature fuel cells, like SOFCs could be used to generate massive amounts of power to supply a city once the sulfur problem (and other issues) is solved. Low-temperature fuel cells are already in use in some laptops and buses and the sulfur is often removed before the fuel is put into the fuel cell.
