Catalyst for fuel cell vehicles?
I'm doing an experiment with a fuel cell car http://www.electronickits.com/kit/complete/solar/fuelcell.htm What would be the best catalyst for use and what would be the best way to provide the catalyst for water? details please!
Answer Short: platinum catalyst is a common catalyst in hydrogen fuel cells. Can be found in catalytic converters, along with palladium and nickel, who also work. The water should be electrolyzed into hydrogen and oxygen first before being presented to the catalyst. Powdered catalyst placed in the carbon sheets is a good idea, because it allows the conductivity of electrons through the electrodes, which contact the carbon on the side of the catalyst. Item no. 7100004 on sale www.fuelcellstore.com appears to be an excellent teaching aid, but it costs $ 63.00 plus shipping. Long answer: (all this was written before seeing his link, you may or may not find useful) Three years ago I made a fuel cell that uses mainly the store, car supplies, with the exception of one special order piece. The fuel cell layers was essentially symmetrical, as I am about to describe. He used a mine (proton exchange membrane PEM), that was the only thing needed to special order. This I got off www.fuelcellstore.com for $ 40 at the time (10cm x 10cm sheet). It is a material called Nafion made by Du Pont, appeared saran wrap. The polymer is available through them, however, has spent three years and may be alternatives. I made a 5 cm x 5 cm square for the fuel cell. This is in the center. As for the catalyst, which began in a catalytic converter off a Ford pickup (any catalytic converter done) and used a hacksaw, file and wire brush to grind the dust out of the combs small airway. The catalyst powder in these converters Most are of platinum, palladium and nickel. I used a thin layer of glue to attach the carbon powder next two 5 cm x 5 cm sheet of carbon paper out of a invoice book that could make carbon copies. Be sure to make little holes or openings in the carbon paper. A leaf was on each side of the PEM faces the catalyst to the outside. The anode and cathode that did not piece of metal air filter used heavy equipment age. It is very useful because there were small 1 mm holes evenly spaced throughout. This was about 5cm x 6cm so that protrude beyond the fuel cell. The top bent back to not playing. One placed on each side with the tabs bent outward. Finally, I built two decks of 1 / 4 inch plexiglass to hold it all together and direct the oxygen and hydrogen through the cell, and water. The interior had to be carved to fit the contents (Nafion, carbon paper, electrodes, etc.) and the holes drilled in the center to accommodate the fat zerks I used to connect my tube. The fat zerks touch themselves in the appropriate size drilled holes before, but do not squeeze to hard or pulling the strings. I can not believe everything you wrote and looked at your link at this time. Anyway, I'm not removed. The materials could seem like a corny, but turn off the fuel cell 50 mV at first, and once the oxide catalyst of my disappeared, 250 mV. A fuel cell to get 700 mV professional. My fuel cell was mainly seen as his own, without electrolisys and the car (I made my hydrogen from a solution HCl and Zinc metal, this is only practical for experimental demonstration). Fortunately for me, I had a lot of these materials, on the one hand, and perhaps an advantage for that reason. Since then I have lost and / or deleted photos and diagrams of my fuel cell that was in school, but I have to paint bitmap quick and I will send to you if you give me your address. Also, tell me your grade / age so I have a better idea of how much aid you can use.
