My daughter wants to construct a fuel cell for a school project. Budget is tight and platinum as preferred catalyst expensive. I know that Gillette razor blades are coated with platinum. Would there be a way to use old razor blades for making a fuel cell?

    $\begingroup$ Umm...Looks to me like "Platinum" is used as a marketing/sales tool. See Gillette's description of their Platinum-Plus Double-Edged Blade, which is made from stainless steel. $\endgroup$ – Todd Minehardt Aug 17 '17 at 19:52

    $\begingroup$ I've been in the Gillette factory near London. I can positively confirm they do coat their razor blades with real platinum, tiny amounts however. $\endgroup$ – Kemmer Aug 18 '17 at 6:05

    $\begingroup$ I've also been in their other factory in Berlin. Same story. The amount is very very small. From memory they use less than a kg to coat millions of blades. Been a number of years ago however. At that time the first gen Gillette sensor came out. $\endgroup$ – Kemmer Aug 18 '17 at 6:10
  • $\begingroup$ @Kemmer Happen to know why they'd put platinum in their razors? Given, it's a minute quantity, but I don't see much point in doing so :/ $\endgroup$ – paracetamol Aug 18 '17 at 12:51
  • $\begingroup$ Not sure why they did it. Only thing I can think of is to increase corrosion resistance. $\endgroup$ – Kemmer Aug 18 '17 at 19:09
