Platinum-free fuel cell developed in Japan
Fri Sep 14, 2007 1:19pm BST
TOKYO (Reuters) - Japan's Daihatsu Motor Co Ltd said on Friday it has developed a technology to make fuel cells without platinum, the precious metal used in the electrolyte process in existing hydrogen-based fuel cells.
By using alkali, instead of acid, anion exchange membranes, Daihatsu's fuel cell can work with less costly metals which are less resistant to corrosion than platinum, such as cobalt or nickel, Daihatsu said in a statement.
Daihatsu, Toyota Motor Corp's minivehicle unit, also said its newly developed fuel cell uses hydrazine hydrate, a liquid industrial material, instead of hydrogen, as an alternative fuel that emits no carbon dioxide.
.....Currently, Daihatsu uses about 100 grams of platinum per vehicle in its hydrogen-based fuel-cell vehicles under development. Ordinary gasoline vehicles use about 5 gram per vehicle of platinum as a catalyst to filter out carbon monoxide and particulate emissions.
Cash platinum traded at around $1,285 per ounce (31 grams) in early European trade on Friday, up more than 10 percent since the start of this year.
I should have chosen "Cut-n-Paste" as a forum name, since that is what I do, mostly.

Bad news for Platinum, good news for nickel
