Hello all,I'm doing a science project related to improving efficiency of proton exchange membrane (PEM) fuel cells / reducing costs of manufacturing PEM fuel cells.I'm specifically interested in developing a more efficient catalyst as opposed to platinum. I have a PEM fuel cell; I got it as part of a fuel cell car kit.Now, I'm not willing to spend much money. I have a multimeter - what I'm wondering is what kind of experiment could I design (with some house-hold items or some relatively cheap ones at some electronics store) to improve the efficiency of the current platinum catalyst?Thanks alot.
performance isn't somewhat lots the variety of automobile used. A van will for sure carry greater products than a bike and the activity could be accomplished precise and directly. determining to purchase an workers time is a factor in performance and the money desires to be generated from someplace. The carbon footprint extends to how the earnings is generated to pay the charges. i would not experience satisfied working for a employer that presented me with a bicycle to grant shelter heavy products in a hectic city centre. it truly is 2010 no longer 1910.
many good links to suppliers and manufacturers. It will take some digging, but it's worth it.
You can try Pt3Co or Pt3Ni catalystsor maybe pure Nickel, but I'm not sure that will work. Both Ni and Co will reduce your cost because they are cheaper than Pt. It's not something you can get at a store, so I'm not sure how you're gonna be able to make it. To make the catalyst, you need to grind it with carbon in a mortar and pistol. And then, you have to coat it on an electrode. You can give it a shot, but usually, someone has to show you how to do it. Kits are pretty efficient. I'm not sure what you can do to improve it. Good luck.
