Updates: Whatever Happened to Fuel Cell Progress?

pRevving Up Fuel CellsProgress toward hydrogen-powered cars depends on less expensive but greater capacity fuel-cell systems [see ldquo;On the Road to Fuel-Cell Carsrdquo;; SciAm, March 2005]. Researchers have taken big steps on both the cost and storage challenges. A team from Quebec came up with a recipe that uses iron instead of expensive platinum to catalyze the electricity-making reaction of hydrogen and oxygen. The key was carbon structures containing microscopic pores, which were filled with iron to provide plenty of active sites for chemical reactions. The iron-based substance, described in the April 3 Science, produced catalytic activity within 10 percent of the best platinum versions and 35 times better than previous, nonprecious metal catalysts./p a href=http://www.scientificamerican.com/article.cfm?id=updates-jun09[More]/abr clear=both style=clear: both;/ br clear=both style=clear: both;/ a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:41bdf7cdbc30710df163fd2cd0f7e990:3knL2gR2YHgPQt%2FKzDoYO6WZs1qoegyEmBEDRevHGUteL7EMqsg7GGPTtrFHNRC0%2Fx9LheTwDDu9'img border='0' title='Add to digg' alt='Add to digg' src='http://images.pheedo.com/images/mm/digg.gif'//a a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:6f8e460a767326170d163393bb063559:NLS5T47Wt319h%2Bg37daKlUvdYQQNYxK80ZF7HcFntzb36JPDoMdubcZyqY3jAA7yQ37wVv8kY8uPOA%3D%3D'img border='0' title='Add to StumbleUpon' alt='Add to StumbleUpon' src='http://images.pheedo.com/images/mm/stumbleit.gif'//a a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:1b9afa2916a33c13f8115da54ab7a43f:cmMkibwPO7LkUVBBbj1R8A53IZgVzewut8DiGPTqZUezdRHD%2FEajfjYd2tOD9asc68RGNDPRgK%2Fk'img border='0' title='Add to Reddit' alt='Add to Reddit' src='http://images.pheedo.com/images/mm/reddit.png'//a a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:da7b272368344090462effce5cc7f815:7sjwL61hqEsNO8ZzfUf1krUrefE%2FXbCN0gpMaNDsWInIgKgSG3MLDtjfSdQ3kStSykZKA8gjZEQ%2Fgg%3D%3D'img border='0' title='Add to Facebook' alt='Add to Facebook' src='http://images.pheedo.com/images/mm/facebook.gif'//a a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:2dc2ccacdcf85a4b19703468917d9d2a:EOPeCfWa59p9Nag8%2FPkhcD2QxJF3yrgTDbI3obMJXy33p%2Fl7jYG4TSzS1mfDClQgBL8QiOdiB%2BW2'img border='0' title='Add to del.icio.us' alt='Add to del.icio.us' src='http://images.pheedo.com/images/mm/delicious.gif'//a a style='font-size: 10px; color: maroon;' href='http://www.pheedcontent.com/hostedMorselClick.php?hfmm=v3:df9ba6b0df6370616ec10069145911ae:%2FtLokoq0%2Bo06ISCF9yQQFBnqfhcwylTlNrhtAdFKqeBtsinD1wbv9he2QU45iW2Y9ClVCmN99AtE'img border='0' title='Email this Article' alt='Email this Article' src='http://images.pheedo.com/images/mm/emailthis.png'//a br clear=both style=clear: both;/ a href=http://ads.pheedo.com/click.phdo?s=c775b9d35391869845f483b16330cb38p=1img alt= style=border: 0; border=0 src=http://ads.pheedo.com/img.phdo?s=c775b9d35391869845f483b16330cb38p=1//a
