I've have just recently gaind intrest in researching up Fuel Cells. I've learnt that there is a PEM (Proton Exchange Membrane). It is made out of Polymer, what is polymer and where can i get it. Is it the plastic CD's are made of?

Yeah, it's probably something fairly specific. The point of a catalyst is that it reduces the energy necessary for a chemical reaction to occur. In the converter of a car, it makes it easier for the crap in the exhaust to react and change to a less harmful form. In a fuel cell it helps along the "2H + O = H2O + Electricity" reaction.

I had heard that they use an alloy....I think it was nickle and something.

I believe the most commonly used catalyst is platinum. Strangely enough, that's also what's used in a car's catalytic converter...it's what makes the converters so expensive...

a catalyst is just a substance that speeds up a chemical reaction....most likely it makes the fuel cell more efficent, but I'm just guessing.
The electrodes should be made of a material that won't oxydise at the high temp condiditons that are present in the fuel cell. I would think something nickle or chome plated would endure it

I guess none of you are a science wiz, or just not intrested in my topic. Can someone respond!

Does someone know what the catalyst is made from, visit the link if you don't know what I'm talking about. http://www.ballard.com/tD.asp?pgid=20&dbid=0
And do i need to have platinum electrodes for the fuel cell to work properly?

what about the permiable membrain in a reverse osmosis filter, couldnt you modify that to preform the same function.

So you think i wont be able to find any Polymer around my house? Like plastic bottles ice-cream containers ect. I just dont want to buy any if i already have some.
There are plenty of polymers in your house, just about anything plastic is a polymer. The question is will you have the right one. Short answer, no. As stated before, polymer is just a generic term, not a specific material. Also stated before, it is a specific, expensive, type of polymer. Being that is is expensive, it's not going to be used in pop bottles and the like.

No, it needs to be a special formulation of plastic to allow it to operate. You can buy it, it's just pretty expensive.
